2 Approach-MECH n 1955, when the first issue of Approach was published, VADM Thomas S. Combs said in his foreword, To realize maximum effectiveness and combat readiness it has been neces sary to place strong emphasis on our aviation accident prevention program. Those words have never been truer and the magazines have lived up to those expectations. Editor, Approach and Mech Naval Safety Center decided to revisit some of the former staff members to update you on what theyre doing today. Just as I was wrapping up on the magazine, I received an impas sioned phone call from LT Neil Tublin, the author of A Simple Solution Missed, on page 16. He felt writing the article was the last thing he needed to do to a put painful situation behind him. Neil will never fly for the Navy again. He didnt follow procedures and it led to the total loss of his aircraft. While I could hear the disappointment in his voice I could also tell it meant a lot to him that no one else repeats his mistake. His article and those like it, is exactly why the magazine began. It took a lot of guts to admit his mistake and for him to look back and trace the steps to discover where he went wrong. It is my hope that his story has an impact on you that will make you think before skipping or missing a step.

FROM THE EDITOR Navy and Marine Corps aviation safety has had its fair share of ups and downs in regards to mishaps as Sailors and Marines have focused on mishap-free flights. The mishap rates have gone down over time and processes have improved. As a result, more units are reaching mishap-free milestones with ease. The purpose of Approach and Mech has always been to high light those milestones as well as making the aviation community aware of accident-prevention methods through stories told by people who have actually experienced mishaps. However, change comes and we begin doing things differently to keep up with those changing times. In the publishing community, weve seen many newspapers and magazines move toward online formats intended to reach larger audiences. Starting in mid-march, Approach and Mech magazines will follow suit with other magazines and be published online only. The magazines will be under the umbrella of a new digital magazine titled 360SAFE. While this is a bittersweet change, because it will likely be my last physical publication, I embrace it since I have seen other publications successfully make the transition. I have worked on eight publi cations that have all eventually made their way to the internet As an editor, my first concern is always about whats best for the community the publication is intended to reach. Those of us at the Approach and Mech staff understand that and we are constantly brainstorming ways to make this transition work for everyone. We know that there are units that have limited access to the internet. Therefore, we are happy to send out digital copies to those who request it. While I cannot predict the future, I do know that Approach and Mech online will continue to provide the same mishap-prevention focused content that the printed editions did. We will continue to accept articles, Bravo Zulus and mishap-free milestone and stats about your units progress. The move to an all-digital publication also opens the doors for new processes and gives us more space to work with. In the past, I could only published eight to 10 articles. Now we can share more information and it will be more up to date. The content will also be shared on our social media platforms. In regards to this final printed issue, it was very tough to decide which articles would make the cut. As usual we receive a lot of good content but I went with what I thought would be the most impactful. I also decided to visit the past and share with you the history of our aviation and maintenance safety magazines. We also I

Approach-MECH 4 M y pilot and I were headed into country on an Operation Inherent Resolve mission. We were tasked with close air support in Northern Iraq. We were excited for the possibility of a busy flight with all junior officer crew. Our brief and preflight were standard, and nothing abnormal was noted with the aircraft. Right before we went up the ladder a maintainer told us that we would be starting on ground power because the battery was weak. When we got in the jet the pilot noted the battery voltage was fine, however, we continued with the maintenance recommendation to use ground power. The jet required multiple attempts to hold ground power. However, once it held the start was uneventful and we had the appropri ate 28 volts on the battery gauge. Though the battery gauge can show critical information regarding the status of PMGs and battery chargers, it is only available in the front cockpit and was not a part of my pilots normal scan. The battery gauge shows either the maintenance or essential bus, and in either case we expect to see 28 volts in flight. Even with the weak battery, we were not concerned with it or the electrical system. We pressed on with no indications of electrical troubles. Our transit into Iraq was normal. As we had hoped, the flight was busy. Checking in with the JTAC we were immediately tasked to scan a few towns and told of possible vehicle-based IEDs that we may be called upon to strike. As we neared our first aerial refuel time we received the clearance for our first attack. We successfully employed an AGM-65E Laser Maverick into the first of the two VBIEDs and headed to the tanker. Upon checking back in with the JTAC after refueling, our wingman cleared us to attack the second target with an addi tional Laser Maverick. We collected bomb damage assessment for the second attack and were expanding our search for activity in the surrounding area when we received the audio indica A WEEK LONG VACATION tions of the MASTER CAUTION. A quick scan of our display showed we had several cautions. The first cautions were AOA TONE and G-LIM 7.5G. This set of cautions is most com monly associated with hung ordnance, or store management issues since the jet is unable to appropriately schedule the G and AOA limit based on the weight of the aircraft. We scanned the stores display and it showed no issues with the ordnance, just the missing LMAV we employed earlier. A look at the checklist page showed a flashing aircraft weight, indicating the jet did not know its weight. With this information I told the pilot it was likely a fuel issue. Before we could begin to troubleshoot further, another set of cautions came up. This time we received more cautions: FCS, NO RATS, RDR OVHT, and CAUT DEGD. I began calling them out, and the pilot reported that we had zero volts on the battery gauge. Since we had both generators online this indicated a maintenance bus voltage of zero. It was at this time that we put our nearest divert, Erbil, Iraq, on the nose. The pilot told our wingman that we were seeing several odd cautions and briefly described them. We expressed our concern that this may be an actual failure and our intention was to divert. Our wingman responded that they would follow us in and that they would handle all communications. Having all our comms handled by our wing enabled us to turn our radios down and talk inside the cockpit. The pilot said he was shutting off the radar in response to the RDR OVHT caution while I broke out the book for the CAUT DEGD. Our PCL steps consist mostly of notes pertain ing to what a CAUT DEGD really means for aircrew that the jet may or may not be able to display new cautions, or remove cautions when they are no longer applicable. There are only three steps for a CAUT DEGD. We executed step one by reset ting the signal data computer (SDC) and, as we did, we noticed A WEEK LONG VACATION BY LT SAM CROUSE, VFA-211 Aviation Ordnanceman 3rd Class William Miller, assigned to the Gunslingers of Strike Fighter Squad ron One Zero Five (VFA-105), arms an AGM-65 Maverick laser-guided missile loaded on an F/A-18 Hornet (Photo by Photographers Mate Airman Kristopher Wilson)

5 Vol. 61, No. 4 the FUEL page only had an estimated fuel level indicated by a flashing value. When this reset failed to fix the issue we cycled mission computer 1 (MC1) power. When we did so, we lost our engine fuel displays (EFD). The cycling of power also failed to fix the CAUT DEGD, so we moved to step three: land as soon as practical. It was about this time that our wingman came up on the AUX radio and told us he had informed the necessary agencies that we were diverting and what approach frequency we were talking to. I switched to that frequency and heard them ask if we were an emergency aircraft, to which our wingman replied yes. I switched our squawk to 7700 and returned to trouble shooting with the pilot. We still had plenty of time to go and were pointed directly to the field. I trusted our wingman would contact us if we needed vectors for the approach. The wording land as soon as practical gave us pause and we briefly had a discussion in the cockpit regarding the pos sibility of heading back to the ship. Hundreds of miles of flight over territory that is at best contested by ISIS, quickly vali dated our decision. Investigating our other cautions and cockpit indications only validated our decision further. We began going through the steps for the RDR OVHT caution. The RDR OVHT caution listed a note that the cau tion would extinguish when the radar was turned off, even if the overheat condition persisted. This note normally would be included to prevent aircrew from turning the radar back on simply because the caution went away. However, for us it con firmed that our CAUT DEGD was real, because we still had a RDR OVHT caution after turning off the radar. We also looked at the flight control system page to determine the cause of our FCS caution and noted that we again had a G-LIM 7.5G, reiter ated on the FCS page. We determined that we had no accurate indications of fuel level displayed in the cockpit. With no work ing EFDs and a CAUT DEGD we were concerned with our ability to recognize any further problems. We noted an FPAS advisory and no information on our flight performance advisory system (FPAS) page, reinforcing that we really did not know how much fuel we had, how far we could go, and if we could even refuel. We discussed that an SDC failure might affect fuel transfer and make airborne refueling impossible. With our decision to divert confirmed, we now began to focus on our approach into Erbil. We needed to start descend ing to make an approach. As we did, I got out the approach plate and swung the course line through the waypoint on runway heading. The pilot offset to the South and began to set up for a straight in to runway 36. As we began our descent, the approach controller told us we would be losing contact with him and to switch tower. I requested the tower frequency and switched up. After that we set ourselves up for a very steep but otherwise uneventful approach. Our wingman took a split from us and got separate landing clearance. We quickly executed HAIL-R and landing checks ensuring we were ready for a shore-based landing. Prior to landing I had plenty of time to determine three things from the approach plate: there was no ground frequency, we had plenty of runway length, and that the copy I had was too faded to determine any taxiway layout. As we rolled out, tower told us to exit the runway at taxiway A2. The pilot responded by telling tower that we required a sig nificant ground roll. He was worried that we could blow our car rier pressurized tires, so elected to use aero braking for as long as possible. As we slowed below 50 knots with plenty of runway remaining, tower advised us that we had missed our assigned taxiway. We told tower that we were unfamiliar with the field and would take longer to come to a stop. Tower then directed us to back taxi and exit on A2. As we back taxied I turned up my map light in another futile attempt to read the taxiway dia gram and told tower that we would require progressive taxi or a follow-me truck. They responded that a follow-me truck was on its way. Our taxi was uneventful and an air force crew was wait ing to guide us into our parking spot at the transient line. Our wingman, met us a short time later. At the flight line, after my pilot hand cranked the canopy open, we were met by former F-18 guys who helped us call back to the boat. Our maintenance department gave us ini tial troubleshooting steps and found a battery charger circuit breaker popped and reset it. We told maintenance that ground power failed to power the canopy, any of the maintenance panels or the interior lighting, and we saw no charge on the bat tery. A rescue detachment was then organized with the parts for a battery charger failure. Our wingman left the next morning and returned to the boat. It would take six days before we left. While we were in Erbil we had abundant time to study all the gear in our sur vival vests, try to piece together what happened with our jet, drink from our souvenir Kurdistan mugs and take turns with a crossword puzzle book. We also had the rare opportunity to see some of the operations there and meet some Kurdish fighters who were incredibly thankful for what the U.S. is doing in the area. Maintenance replaced the battery and battery charger the same night they arrived. The job only took a few hours; most of it spent dropping the gun out of the way. The maintainers told us the bat tery charger was surrounded by charring where it had appar ently shorted out. With the new parts installed, our start-up was uneventful and the flight back was completed without incident. Safe on deck on the ship, we were able to start analyzing what had happened, and how our failures were related. All of our failures were related to the battery charger. The battery was likely weak on deck due to either being undercharged by the charger, or possibly due to an intermittent short in the bat tery charger. When the battery charger shorted out in flight, it meant that the maintenance bus became unpowered, and with it the SDC. With no SDC the jet was unable to calculate its fuel load and could not determine its weight accurately. In this case the jet was able to display estimated total fuel only, and left all individual tanks indications at their pre-failure value. In addition, our FPAS could not tell us our range or endurance due to the lack of fuel information. Interestingly, the estimated fuel value provided by the jet (using pre-failure values and fuel burn over time) at touchdown was only a couple hundred pounds off from the level that the jet reported after it was repaired. In addition the lack of power to the SDC caused us to have a CAUT DEGD, and to lose EFDs and the ability to read MSPs. This DEGD had the serious implication that any future cau tions or advisories may or may not be presented to aircrew and Looking back on the flight, I am certain we did the right thing diverting into Erbil.

PAGE 8

6 Approach-MECH we were seriously limited in our ability to tell if the jets status was degrading further. With the SDC unpowered, we lost some fuel transfer logic including the ability to fill or transfer from our centerline external tank. The RDR OVHT caution seems to have been unrelated but it served a good purpose in getting us to take the CAUT DEGD seriously. In addition to all the failures we knew about we also lost some redundancy for other systems. The flight control com puter (FCC) and inertial navigation system (INS) keep-alive circuitry are powered by the maintenance bus. If we were to lose primary power to either, we would lose some functionality for a short time until back-up power sources kicked in. Looking back on the flight, I am certain we did the right thing diverting into Erbil. The inaccuracy of displayed infor mation, coupled with our correct assessment that fuel transfer would be affected by the SDC failure led us to divert. Though we never related our problems back to a battery charger failure in-flight, we were able to come to a remarkably close under standing of what had failed on our jet and why. Task shedding communication responsibilities to our wingman was instrumen tal in enabling the effective conversation we had in the jet. Had we decided not to divert we may have found ourselves over Iraq unaware of further compounding failures and unable to receive fuel in order to get home. While our crew resource management (CRM) was excel lent for the most part, it broke down in a few areas. While the conversation about our failures led to an accurate understanding and sound decision making, it put us behind timeline coming into the airport to land. With both of us busy troubleshooting the jet, we simply waited too long to start focusing on land ing. We both recognized the issue and were very thorough in ensuring the jet was configured appropriately. The pilot did ship-to-shore checks and landing checks aloud, which I echoed challenge and response. After this we had a what are we missing? conversation where we discussed the runway length, desire to avoid braking hard on carrier pressurized tires, and that we did not expect any control issues. While this quick but thorough ORM process mitigated any problems, we should have devoted some of our discussion to landing as soon as we solidi fied our decision to divert. The second breakdown in CRM was a minor one. When we missed the taxiway and accepted back taxi instructions, we allowed tower to cancel our wingmans landing clearance. Our wingman had taken an appropriate split to land after us and now had to do a 360 overhead, potentially putting them in a dangerous spot, low and slow over Iraq. Once we were on deck we started to taxi behind the follow-me truck while our wing man was rolling out on the runway, effectively leaving them to wait for the follow-me truck to come back after taxiing us to the transient line. These were minor things, and it could be argued that as the emergency aircraft we should just do our part to get the jet on deck. However, once we were on deck and felt safe, we easily could have requested to roll out to the end of the runway to wait for our wingman and taxi as a section. The major takeaways from the flight were that we had a limited understanding of this part of the electrical system, specifically battery charger failure, prior to the flight. Battery charger failure is not a common failure and does not have its own emergency procedure. The only way to figure out the systems lost with a battery charger failure is by using a pull out appendix page of the big book NATOPS for what each electri cal bus powers. This information is not found anywhere in the pocket check list. Additionally, prior to this flight my pilot did not check the battery voltage gauge as part of a normal scan, expecting to only need the gauge prior to and after start, or during a dual generator failure. Without checking the voltage gauge throughout the flight we do not know if our battery char ger failed suddenly or if it gradually failed with a slowly decreas ing voltage. A gradual decline in voltage may have clued us into the failure and allowed us to troubleshoot and divert before we lost crucial systems. Overall I would call the flight a success. A wingman who was spring loaded to offer assistance without hopping into our cockpit unnecessarily, and a detailed conversation in-cockpit, turned a bad situation into a chance to see the world a little. We effectively employed two Laser Mavericks on vehicle borne IEDs, handled a compound emergency to a good conclusion, and spent six days seeing a side of Operation Inherent Resolve we otherwise would not have been able to see.

7 Vol. 61, No. 4 BY LT GREG MAYERS, VFA-113 t the end of the first week of Composite Training Unit Exercise (COMPTUEX) I was launched on the first event of the day: a good deal BFM hop with a Super Hornet from another squad ron. As a nugget and non-section lead, I was very excited at the opportu nity to fight a strike fighter tactics instructor (SFTI) and have some fun at the same time. The weather that day was perfect. The launch, tanking, and rendezvous all occurred uneventfully. After the third fight we discussed having enough fuel for one more quick set. As we were setting up our positioning for the last set, I heard Bettys voice and saw two red lights appear in front of me. Bleed air left, bleed air right. Very quickly thereafter, the lights extin guished and two BLD OFF cautions displayed indicating the jet detected the leak and attempted to stop it automatically by com manding the bleed air valves closed. Since the red lights went away, it seemed the system worked. I immediately went through NATOPS boldface procedures. I was now breathing emergency oxygen and was luckily already below 10,000 feet MSL prior to the warnings. I went through the procedures methodically, remembering no fast hands in the cockpit. At this point with aviate and navigate being solved, I communicated the problem and my fuel state to my flight lead. He was very calm and collected, and started directing the flight through the logical steps to get me safely aboard. Meanwhile, I executed the rest of the proce dures in the NATOPS pocket checklist. I also decided to stow my emergency oxygen and save it for the final approach. We discussed our gameplan on our tactical frequency. He would enter the low holding pattern for recovery while I would stand by outside of the boats airspace. We would leave it over to the Air Boss to decide when he wanted me to recover, and my lead would monitor the rep frequency the whole time. It was about 20 minutes until the next launch, and my flight lead had us switch up to strike, relaying that we would need a representative from my squadron on the radio for an emergency. He then switched us to marshall where he mentioned that I was having a problem and would need priority handling. We were then directed to switch to tower. At this point I was holding 15 miles behind the ship at about 6,000 feet. With the ECS switch in OFF/RAM, the slow speed of max endurance was insufficient to keep the cockpit tempera ture down, however, at this altitude and airspeed, it was still tolerable. I switched to tower where the Air Boss was aware I had a problem and the rep was standing by. I let the rep know where I was, what my fuel state was, all the cautions that were displayed at the time, and all the procedures that had been done. He backed me up with the NATOPS pocket checklist and con firmed we had not missed any steps. Dual bleed air cautions often result in a pull forward aboard ship. However, because the bleed air leak detection system appeared to have worked properly with the warning lights going out, no secondary indications, and the presence of an MSP 831, the decision was made for me to recover at the scheduled time. In addition, with the next event already getting ready to launch, it would have taken just as much time to pull forward as it would have to recover at the normal time. The plan was made to have me recover first, ahead of the COD, on a straight in. I was told to expect to shut down in the landing area and get towed to park ing after the arrestment. When bleed air is turned off several systems are lost. While some are intuitive such as air conditioning and pressurization, subtle ones such as throttle-boost did not occur to me. The rep made a good recommendation for me to play with the throttles to get a feel for non-boosted power changes. As the launch got closer to completion, the Boss told me to hold around eight nautical miles behind the ship at 3,500 feet. Once told to charlie I put my mask back on and resumed emergency oxygen flow. At five miles with the landing checklist complete, the cockpit temperature rose significantly. I reported three miles to tower and began my final descent. I recovered uneventfully on board the ship, shut down in the landing area and got towed to park ing. During the tow, my emergency oxygen ran out and I had to remove my mask. Cumulatively, it felt like I had not worn the mask for more than five to 10 minutes, so with all of the holding the conservation was a necessity. Once chained down, I opened the canopy and was thankful that I was safely on deck and finally cooling down. There were a lot of good lessons learned during this event. Lots of things were done well, and a few things have been done better. Crew resource management was key. The communication between my jet, leads jet, the tower, the rep, and the squadron duty officer was crucial to making the right decisions. Being a charlie pilot, I obsessively reported my fuel every time I spoke to somebody new. My leads assertiveness and leadership was great in ensuring that no time was wasted and the situation was set up for success early on. I could have been more prepared for the tougher throttles and the increasing temperature, and the fact that I was surprised by it means I definitely needed to improve my bleed air systems knowledge. It was a good thing that I was hydrated and that I was near the boat. If this had happened farther away and the temperature kept rising for a longer period of time, there could have been more serious physiological con sequences that could have precluded a safe trap. NATOPS says that in OBOGS aircraft, there are 10 to 20 minutes of oxygen in the emergency oxygen bottle. However, a warning says that under less than optimum conditions, as few as three minutes of emergency oxygen may be available. In my case, I did have more than three minutes of oxygen but certainly not 10. Overall, Id say this event was handled very well and exhib ited good CRM and solid NATOPS procedures. In naval aviation, we always need to be prepared for if and when things do not go according to plan. When game time comes, it is the knowledge and execution that gets you home safe.

BY LT DESMOND FOURNIER, VT-30 I t was a special day. I was excited to be flying my first 2P-2P flight, which is a flight where neither pilot is a qualified (CTPC) carrier transport plane commander (our communitys fancy name for an aircraft com mander), but both pilots are designated as a (CT2P) carrier transport second pilot. These flights can be scheduled for training and serve as a useful platform for gaining experience and hours on two 2Ps at once, enabling them to achieve the 700-hour OPNAV require ment to become a CTPC. Not only was I about to conduct my first 2P-2P flight with a buddy from flight school, I was going to have the honor of signing for the plane. I wanted to make sure that everything went right. At the brief, we planned to take off early to ensure that we landed on time, fuel up at the hot pits, and hot switch the plane over to next crew without a hitch. The next crew that was flying a paradrop mission involved having our outgo ing commodore do a tandem jump with the Navy Leap Frogs. I didnt want to be the one that broke the plane. Everything was tracking smoothly until I went to the paraloft to sign for my gear. I need one of these, right? I said to the PRs as I was pre-flighting my CMU-33 vest and I pointed to the holster for my SRU-42 bottle, which was empty and missing. The PRs began uneasily looking through MAFs and the storage compartments to see if anyone had serviced the bottle without putting it back. One of the PRs asked, When did you see it last? I remembered that I had it for the flight last night, but I didnt notice that it was missing until after ward. I had failed to do a proper post-flight! I thought about where my CMU-33 vest was last. Our CMU-33 vests are not required to be worn on normal flights conducted over land, and we routinely hang them on the cargo cage just outside of the cockpit. I flew 25 last night and hung my vest on the cage. It probably fell off there, I told the PRs as they communicated to maintenance control that I had gear missing and we needed to conduct a foreign object debris (FOD) search on aircraft 25. This placed the aircraft in a down status until the FOD was recovered. If not recovered with a FOD search, the chiefs in maintenance control would be unable to release the aircraft safe for flight; only the maintenance officer could release the aircraft. This is not exactly how I wanted my first mission as an aircraft commander to go. The bottle was eventually found in the cargo cage of the aircraft. Once verified as mine, I was then able to sign for my survival gear, sign for the plane, and conduct the mission with out further incident. I was lucky in a couple of ways that day. First, I was lucky that nobody had flown since my last flight. Its not often that any crewmembers from the last flight of the day, landing at 2045, are scheduled to be on the first flight of the day the next morning. If anyone had gone flying with my SRU-42 bottle in the plane, it would have placed aircraft and crew at risk if it was loose as it could potentially be a missile hazard for a catapult launch or arrested landing. We werent conducting any carrier operations, but it could get lodged somewhere and possibly damage some aircraft components. Second, I was lucky that the SRU-42 bottle was recovered and it didnt cause any issues for my first 2P-2P flight, or down the aircraft that the commo dore was planning on using, as it was the only up aircraft our squadron had at the time. It was truly a lucky day and a wake-up call to pay close atten tion to details. Theres no reason that any mission should be jeopardized because a pilot doesnt take a couple of minutes to do a post-flight inspection on his or her gear. This experience shows that it is important to not allow complacency to take hold in any facet of an operation, be vigilant for FOD, and perform thorough pre/post-flight inspections of your equipment so you can always account for it. If you dont, you will cause more headaches, or worse. Wheres the FOD? Approach-MECH 8

10 Approach-MECH T he maritime patrol and reconnaissance (MPR) com munity takes pride in its anti-submarine warfare (ASW) prowess; we train for over a year to become experts in the art of tracking and killing submarines before deploying. The capstone of all of our ASW training is the Torpedo Exer cise (TORPEX), often the final hurdle before a combat aircrew is fully ASW qualified. My crew was stoked to have our TORPEX at the Nanoose Range just 30 minutes North of NAS Whidbey Island, saving us the ordeal of a 10-plus hour round trip flight to the range off the coast of Southern California. The only drawbacks to the Nanoose Range are the size of the airspace, just over 12 miles, and its proximity to very busy air corridors. The range lies beneath Vancouvers Class B approach cor ridor and is nested against the shore of Nanaimo, a popular sea plane destination serviced by Victoria, Seattle, and Vancouver Harbor. Another factor that plays into the events leading to this article is that the NOTAMed airspace, CYR-107, is not entirely colocated with the underwater weapons range where our target can operate. The end result requires us to fly Southeast of CYR-107 outside of our protected airspace and closer to the seaplane corridor between Vancouver and Nanaimo, Canada. With these known hazards, I was fortunate to have two very experienced crewmen with me in the flight station. My patrol plane commander (PPC) had 1,000 hours of flight time and sitting between us was a salty instructor flight engineer (FE) with more than 4,075 hours in the mighty P-3C Orion. As we approached the TORPEX range, we were talking to Victoria terminal and were given a descent to 4,000 feet until cleared onto the range. Once we were cleared, Victoria Terminal called VVGK801, radar service is terminated, frequency change approved. Contact this frequency five minutes prior to depart ing CYR-107. At this point we were on our own.We could no longer rely on ATC for traffic calls and the extreme amount of chatter on the frequency crippled CRM between the flight sta tion and tactical crew. We elected to detune Victoria terminal and focus our attention on the mission at hand. After all, as long as we stayed in CYR-107 we were in protected airspace. An hour and a half later we were well into our TORPEX at 300 feet and we were knocking it out of the park. Our acoustic BY LT JACK DEVER, VP-46 Routine Mission, Non-Routine Environment

11 Vol. 61, No. 4 operators and tactical coordinator (TACCO) were on top of their game and we were sure we would be getting a near-perfect score. We were in a shallow left hand turn to set up for our last simulated attack when our FE called traffic 10 oclock. I was at the controls, saw the traffic, and continued the turn, tighten ing it up past 45 degrees AOB in order to ensure safe separation from the seaplane. I estimate the seaplane passed roughly half a mile away and approximately 200 feet above our altitude. At this time the crew recognized our target had maneuvered just outside of the CYR-107 airspace, forcing us to maneuver within close proximity to the Nanaimo Vancouver seaplane corridor. Re-alerted to the hazard of light civil traffic, we re-empha sized the need to maintain a good VFR scan for traffic. Gener ally, a P-3C Sensor 3 (SS3) provides excellent backup as he has an IFF interrogator and controls the APS-137 radar. The IFF interrogator can reliably pick up Mode 3 traffic but only if they are squawking and the radar can pick up air traffic if the antenna is inclined level with the horizon. Unfortunately, the seaplanes in the Pacific Northwest do not typically squawk and our SS3 was busy tracking surface traffic intent on sailing through the torpedo range. Thirty minutes later, we finally dropped our MK-46 REXTORP on the target, completing the TORPEX. Range control immediately directed us to climb to 1,000 feet (as previously briefed) in order to provide adequate separation with the range helicopter, soon to be in bound to retrieve the REX TORP. I was still at the controls and initiated a climb to 1,000 feet, the PPC began to work the flight management system to coordinate our return home, and the FE was heads down setting the fuel panel for the transit. As I leveled the aircraft off at 1,000 feet, I looked up from my altimeter and immediately saw a seaplane; this time it was filling up the entire windscreen and was at co-altitude. I imme diately chopped power and dumped the nose seconds before the seaplane passed directly overhead merely 200 feet above us. Our SS3 operator confirmed that the seaplane was not squawking Mode 3. As a community, we are accustomed to operating alone and unafraid hundreds of miles from the nearest airfield or seaplane. We often conduct ASW in open-ocean or within the protected airspace west of San Diego where there is a reduced risk from midair collisions. It is easy to become complacent on the rare day you actually get scheduled for Nanoose. Most aircrew in the squadron has gone there just a handful of times, and some never get the opportunity. Complacency and perceived pressure are the causal factors for this near mid-air. Just because it is a routine mission does not mean it is in a routine environment. On the day in question, the flight station was operating with a due regard mindset, focusing on placing the aircraft in the best position for the TACCO, anticipating where he would want the aircraft to be. The risks specific to the Nanoose Range had slipped to the back of our minds and we were not proactively searching out traffic. With the range helo spinning on deck there was perceived pres sure to climb to a safe altitude to allow the helo to retrieve the REXTORP. Once given the command to climb, we should have informed the range to stand-by until the aircraft was back in the protected airspace CYR-107; a missed opportunity for time critical risk management (TCRM). We also placed too much emphasis on technology to keep the aircraft out of harms way. Tools like an IFF interrogator and TCAS (if so equipped) are excellent; however, they require other traffic to be squawking. My advice to my fellow aviators is to remain vigilant and maintain situational awareness. TCRM/ORM is not simply a buzz word; proper application could have prevented this near mid-air collision. Just because you are doing a routine mission does not mean you are immune to the hazards of an abnormal environment. At the end of the day, keep your skulls up. Nothing is better than a good set of eyes to keep you clear of other traffic and get you home safely.

13 THE POWER OF CRM I was excited for my SFWT level II Red Air event. After a busy COMPTUEX as a brand new JO, I had returned from POM leave the previous week and passed my NATOPS check with flying colors. My XO (as flight lead) gave a thorough brief and I walked to the jet. During a sweep of the cockpit, I noticed the ECS mode switch in MAN and placed it in AUTO. During start up I adhered to my habit patterns to include watching the CK ECS light illuminate while cycling the bleed air knob. Passing through 10,000 feet, I glanced down at my cabin pressure gauge and confirmed that it was at 8,000 feet per its normal schedule. After a G-awareness maneuver at 17,000 feet, my flight lead initiated a climb to 30,000 to join another section of red air and set up our first presentation. I was hanging on in TAC wing position while lead maneuvered to get us in position. At this point, I noticed that the ambient cock pit noise was quieter than normal and a pressure was building up in my ears. I glanced down at my cabin pressure gauge and got the first hint that something was wrong it was reading 27,000 feet, the same altitude indicated by my altimeter. I also noted the CABIN and CK ECS lights illuminated by my right knee. Seconds after reading the gauge, I inventoried my hypoxia symptoms: tingling and coldness in the fingers, flushing hot feeling chest and lightheadedness. I had been too busy flying formation to notice! I immediately executed the boldface for hypoxia/decompression sick ness, pointed at NAS Oceana and started my descent to below 10,000 feet. Thirty seconds after selecting emergency oxygen my symptoms rapidly decreased. I noticed the CABIN light extinguish descending through 12,000 feet, and I was symptom-free within five minutes. With good CRM between myself and flight lead, I landed at home field without further incident. Investigation post flight revealed the culprit: the CABIN PRESS switch was in the DUMP position, making it impossible for the jet to hold cabin pressure. Even with a nugget pilot like me, preflight is normally briefed as standard. It carries with it the assumption that aircrew execute on deck procedures per NATOPS. Though during my cockpit preflight I noticed one switch out of position, I did not notice a switch that was only two inches away. Additionally, we execute checks at 10,000 feet to verify the pressur ization is scheduling normally. Had I looked at the cabin pressure gauge for more than a split-second, I would have noticed it was not holding at 8,000 feet like it should. Lastly, it is important to scan all of our displays throughout the flight. Looking at the warning light cluster by my right knee was not part of my normal habit pattern, as most warnings and cautions are displayed on the DDIs. Had I noticed the glaring CABIN and CK ECS lights sooner, the whole emergency could have been avoided. The short flight ended with an unevent ful landing but it could have been a lot worse. Hypoxia is a hazard we face even when we execute correctly. Going back to something as basic as a proper preflight prevents us from being a hazard to ourselves. Vol. 61, No. 4

BY LT NEIL TUBLIN, VFA-14 16 A SIMPLE SOLUTION MISSED Approach-MECH I will never fly a plane for the Navy again. I didnt know my NATOPS, how to follow pro cedures or communicate. Its hard for me to write that sentence. Its hard for me to read it. Its even harder to live with it. This may be an oversimplification of the scenario but I dont think anyone who knows mewould say that its incorrect. Everything prior to getting into the jet that day was standard. After man-up, some BLIN codes popped up during my FCS IBIT, causing me to get behind time-wise while troubleshooting the flight control system on my aircraft. As fate would have it the BLIN codes would not clear and I would have to shut down the jet and start up another. I read and signed for the spare aircraft, side 210, at the boarding ladder. As anyone stationed at NAS Lem oore knows, MOA time is precious and stringent. If you miss time on the front end you wont be able to make it up on the back end. My flight lead (who is also my commanding officer) and I only had area A of the NLC MOA for one hour and our entry time was fast approaching. I could feel myself wanting to move faster while pre-flighting the spare, but I fought this temptation and made a conscious effort not to skip anything. Here is where I mentally take out my pen and paper and begin to count the number of times I could have prevented what would ultimately become a class A mishap. After turning on the bat tery, I began the standard ditty the FRS teaches, Parking brake, set. Anti-skid switch, on. Master arm, safe. Wingfold, matches After confirm ing that the wings were spread, I brought my eyes back to the switch and saw that it was in the fold position. I matched the switch position with the wings and continued my ditty. Later in the startup I would also noticed that the ECS MODE switch was in the OFF/RAM position. This is where I should have paused and thought to myself, What else is wrong in my cockpit? I had rarely (if ever) seen a switch in the wrong position during start-up, yet now I had two and didnt think anything of it. I should have been suspicious as to what I hadnt found. The INTR WING switch was in INHIBIT. Things can move pretty quickly in the Lemoore MOA since the airspace is directly overhead the airfield. One moment youre on the ground and the next youre checked in and getting ready to execute your first BFM set. On this flight we did just that, we took off uneventfully and went right into the mission. Just before my bingo bug went off, with the fuel reading 11.1, I switched my bingo setting to 9.0 as we are taught. I also noted that my external tank

PAGE 19

17 Vol. 61, No. 4 was empty and switched from my external fuel display to the internal fuel display on the Engine Fuel Display (EFD). I even noted that my feed tanks were full. However, I had skipped a crucial step in this procedure. The ditty that is taught at the FRS is, External tanks empty, WING TANKS TRANSFER RING, feeds nearly full, resetting bingo to 9.0. I did not take note of the state of my wing tanks. At 9.0, I was once again resetting my bingo bug to the briefed joker fuel state of 6.0. At this point I did not execute the proper check, WING TANKS TRANSFERRED, feeds nearly full, resetting joker. Add another two tick marks to the count of times the class A could have been prevented. I have a fairly good recollection of how everything occurred after the Knock it off call on our last BFM set. The one thing that I cant specifically recall is when I received the FUEL LO caution. The data shows it popped during the final BFM set and that I extinguished the master caution and continued fight ing. Without a doubt, the FUEL LO caution came on at a time much earlier than it should have, but I didnt make the con nection. Had I merely mentioned the caution to my flight lead (or later on to the SDO) A/C 210 would still be on the flight line. After fencing out we were just northwest of the field, in what you could almost call a wide downwind, setting up for the initial to runway 32L. After a fan break, I made my call, Dash two, gear, as I watched the three gear lights illuminate, then completed my landing checks. At the 180 I began my approach turn when I suddenly lost my AOA-bracket and received an FCS Caution. Had I glanced at my right DDI, I would have seen a four-channel AOA failure. This is a perfectly safe condition to land the plane with. I could have maintained an airspeed equivalent to on-speed AOA, rec ognizing that the AOA-bracket and AOA indexer lights would no longer be present. In the groove as my flight lead touched down, I notified tower that I would be executing a wave-off, I didnt feel comfortable landing. I told my lead why I had waved off and he prompted me to take a look at my FCS page. Sure enough, it indicated that I had a four-channel AOA failure. As I began a climb to 2000 feet in order to troubleshoot, my lead and I both switched our Aux radio to the base frequency to go through the procedures with the SDO. The SDO started by asking which cautions I had. I informed him only of the cautions relevant to my wave off another huge tick mark. We methodically stepped through the four-channel AOA procedures, which took about two turns in holding overhead. By the time I was turning toward downwind to set up for the straight-in, my fuel was reading a 1.9 and Tower had just cleared another jet into the break. ATC and my flight lead both came up on my PRI and AUX radio at the same time and I was unable to hear either of them. After sorting out the radios I real I couldnt believe that I was going to have to eject. I placed my PCL from my lap to the side, assumed the proper body position, and pulled the handle. ized I was cleared to land on my straight-in approach and that my flight lead wanted me to inform Tower that I was priority fuel, nearing emergency if I did not land immediately. Neither of us realized that I had long passed priority fuel. The time to declare emergency fuel would have been after receiving the FUEL LO caution. I began to turn toward a base leg. This is when I finally saw that the dominoes were falling. I noticed that my airspeed was at 116 knots, about 15 knots slower than it should have been. I immediately pushed the nose over and placed my throttle forward to try and regain my airspeed. I didnt feel the jet respond as it should have and I made a call to my flight lead, Im losing it, Sir. The final indications that I saw from a quick scan of my displays were 106 KIAS airspeed in the HUD, a 1.7 fuel load on the EFD, and an L FLAMEOUT caution on my left DDI. Just after I saw the L FLAMEOUT caution, everything in the jet turned off. It was the most terrifying silence Ive ever experienced. I knew that I must have lost both engines. I didnt get any response from the throttle or stick and stared for a moment at the farm below that I was plummeting towards. I couldnt believe that I was going to have to eject. I placed my PCL from my lap to the side, assumed the proper body position, and pulled the handle. A few months later my CO gave me a book with a collection of stories from people who have had to bail out of their air planes. Almost all of the stories Ive read on the subject involve some sort of fire fight or a systems problem with the airplane that was out of the pilots control. In my case, it was one switch being in the incorrect position. A switch that may have been hard to see on preflight but could have been caught on multiple occasions throughout the flight. It turns out that I had flown a different jet with the switch in that position two weeks earlier and received a FUEL LO two minutes prior to landing. This means that you can double the amount of times that I missed the switch and the significance of the caution. The first time I got lucky and landed without incident. I should have declared an emergency and asked the question on deck. I also could have looked it up in NATOPS and realized that what I saw was abnormal. Instead I didnt communicate and didnt follow up, allowing the same issue to come back to haunt me in a different jet on a later flight. There are some that Ive told this story to who have said that it easily could have been them. Most say they would have missed the INTR WING switch being in the INHIBIT posi tion during their cockpit sweep and start up. Many others have said they could have missed the fuel checks while executing BFM in the MOA. What it really comes down to, in my mind, is that I received a FUEL LO caution and didnt recognize that it was abnormal, or at the very least communicate that I had received it. Its a tough lesson learned. Hopefully those who will continue to fly can learn from my mistakes.

D 22 ragon in Distress W e were 12 days into tailored ships training avail ability (TSTA) onboard the USS Carl Vinson (CVN-70). It was the average Groundhog Day of maintaining aircraft, waiting in line to eat, and going to sleep, just to do it all over again. Complacency had truly set in. Near the end of our shift, we were finish ing up our repair job on dragon 300 so that the oncom ing shift didnt have to take over half way through a job, allowing them to concentrate on the flight schedule. Our power plants work center was finishing up a nearly three month special inspection when one of the mechs said to me, AD2, just go in and let maintenance control know were almost done. We can finish installing the fasteners. I agreed and thought to myself, I have to come back out when they finish and CDI the work. Just after I got to the maintenance desk, one of them ran up and told me, Theres something you have to see. We headed back out to hangar bay 2 and dragon 300, which had flown onto the ship several days earlier. He showed me that the starboard engine variable exhaust nozzle (VEN) eight oclock position second ary seal was missing, three-fourths of the two oclock position was missing and the nine and 10 oclock position secondary seals were nearly cracked in half. We stood staring at it in confu sion. How could this have happened? How was this missed? Our initial response was to look into the his torical work orders to find what work had been done. Dragon 300 joined us on the ship about two weeks into TSTA. We hadnt performed any maintenance on the starboard engine VEN since a 200 engine hour inspection three months prior. The jet had not flown for the previous two months due to some hard downing discrepancies; heavy corrosion gripes, and fuel cell leaks in tanks 3 and 4. The jet had only been flown on a functional check flight (FCF) in Lemoore and then out to the ship in those two months. Back on the ship, as soon as 300 landed and moved to the hangar bay, the exhaust covers were installed, hiding the damaged VEN. After discovering the BY AD2(AW) COREY ROY, VFA-192 missing seals, we immediately notified maintenance con trol. Quality assurance (QA) promptly began their investi gation. As for the damage, both the power plants shop and QA agreed that a loose one-fourth inch nut was respon sible for the damage. We believed that the nut was not tightened all the way and the force of the exhaust dislodged the eight oclock secondary seal. When it came loose, it hit the 2 oclock position which loosened that secondary seal, and in turn, flung it across and hit the nine and 10 oclock position. Quality assurances investigation, along with the day check maintenance crew, discovered a secondary flap and base were also damaged. This incident reminded us to always ensure that every nut and bolt is tightened appropriately. Each part of the aircraft, whether an engine mount or a panel cover, is criti cal to the safe operation of the aircraft. It is paramount that each component is installed in accordance with the appropriate publications. A single loose nut can cost a squadron man hours and parts that we cannot afford. Damage to a starboard engine variable exhause nozzle left maintainers in a state of confusion during a routine check. They later discovered that a loose one-fourth inch nut was responsible for the damage. (Photo courtesy of VFA-192) Approach-MECH

23 BY LTJG LUKE GUNDERSON, HSC-14 O ur primary mission in aviation maintenance is to provide safe-forflight full-mission capable aircraft in support of our combat readiness. Safety is a cornerstone of preserving combat readiness and saving lives. We must focus on safety both in the work we do and the equipment we use, including the repair of damaged equipment to save lives and money. Common sense should dictate that we draw a line between repairing versus replacing equipment, especially when the safety of the maintainer becomes an issue. During a deployment, an aviation electri cian (AE) was completing a routine blade fold switch adjustment as part of a phase-D inspection. The aircraft was in the hangar bay, connected to external power while the AE attempted to adjust the blade fold switch with a blade fold test unit box. While on top of the aircraft, the AE pulled the test box by its external power cord for extra slack with their right hand. As the AE tugged for more slack with their right hand and held the test box with their left hand, the shell back connecting the power cord to the test box arced and elec trocuted the AE. Due to the intense heat and force of the arcing, the external power cable attachment melted and completely detached from the box. As a result, the AE looked down to find burns on their left hand. The AEs fellow maintainers reacted quickly to discon nect external power from the aircraft and get him medical attention. The AE spent one day sick in quarters (SIQ) and three days on light limited duty (LLD). During the ensuing investigation, it was determined the AE shop had previously repaired the blade test set power cord. The cord had undergone a 56-day inspection, just four days earlier, passing all applicable tests with no known discrepancies. However, since the previous repair was on the internal wiring, there was no way to determine that the wires had twisted, which eventually led to the short at the shell back. Because of this mishap, HSC-14 squadron personnel shall no longer repair damaged cords themselves but instead, should either properly dispose of the cord or turn it into AIMD for repair or replacement. This is a case of using the right person for the right job. Only by using power cords that have been repaired by a certified technician; will we ensure that our maintainers arent subjected to electric shock while conducting routine maintenance. Routine Maintenance Gone Awry During a routine blade fold switch adjustment, an aviation electricians hand was electrocuted. The intense heat and force of the arcing caused the external power cable attachment to melt and detach. (Photos courtesy of HSC-14) Vol. 61, No. 4

Following the tail being spread and stabilator unfolded, it came time to spread the main rotor blades. With a spread-qualified maintainer in the aircraft, wing walk ers and safety observer in place, the maintenance team was ready to begin. The spread sequence started and the blue and black coded blades slid into place. As designed, the blade lock pins drove into place and the pitch lock pin retracted. However, the red blade stalled over the engine exhaust cowling as the yellow blade spread fully. Sud denly the stalled red blade dropped, causing it to impact the satellite communication (SATCOM) antenna and fuselage. The damage caused to the SATCOM antenna alone would have been a downing gripe on the aircraft but the larger issue was the damage to the rotor blade. The rotor blade had some chips on the trailing edge with some smaller dents throughout. The blade failed the coin tap test and was well out of dent limits on what is allowable on a rotor blade. The cost of replacing a single main rotor blade is $200,000, leading to classification as a class C ground-related mishap. Fortunately, the damage to the blade was depot level repairable, driving the monetary cost down and the mishap class to drop from a C to a D.

Once the initial notifications were complete, it was time to determine what caused the blade to drop. Looking over the rotor head, it appeared the blade lock pins were driven in and the pitch lock pin had been retracted, all before the blade was in the proper position. This pointed to the problem being with the blade fold motor assembly. The blade fold motor assembly contains two separate main gears. The segment gear is used to fold and spread the blade; the spur gear drives the blade lock pins in and out. There is also a sensor on the blade lock pins that tells the system they are extended and that the pitch lock pins can be retracted. After removal of the blade fold motor assembly, it was difficult to turn in any direction. Inves tigation found that the segment gear skipped teeth inside the blade fold motor assembly, which then caused the spur gear to start driving the blade lock pins in prema turely. Once the blade lock pins completely drove in, the system logic commanded the pitch lock on the red blade to drive out and allowed the blade to drop. In the dynamic world of helicopter aviation, material failures can happen. However, it is unusual for a com ponent failure to cause significant damage to another part. In this case, if the motor had failed in any other way the blade would have just stopped instead of falling. If the motor had spread just a little bit before failing then maybe the blade would have missed the aircraft com pletely. Make every effort to plan for every single failure or contingency. Peform maintenance by the book, every step every time, and hopefully avoid injury to personnel. At the end of the day no one can fault you for doing the right thing.

1960s 1970s 1980s 1990s 57 Years of Aviation Maintenance Safety Magazines 26 Approach-MECH less like a magazine and more like a safety manual. It fea tured a mechanic on the cover and the magazine the pages included analysis and statistics covering a wide range of main tenance safety topics. In the 1970s Mech actually included study material for maintainers to use in their every day lives at work. At the end of each session there were questions with answers provided. The magazine got an early start on safety related infographics. By the 1980s Mech was pub lished as a magazine vs. a manual but the staff still relied heavily on the maintenance instructional manuals to inform their target audience. It also written by Sailors who had experienced a mishap. Mech was mostly in color by the 1990s but it was primarily only used on the front cover. The magazine was more visu ally appealing with the use of artist depictions. Each issue consisted of a note on the importance of the technical publications library.

Vol. 61, No. 2 2000s 2010s 2013-15 Present 57 Years of Aviation Maintenance Safety Magazines MECH 27 With a full color digitally designed magazine, the Mech was down to a staff of four and it featured less illustrations and more digital photos taken by Navy photojournalist. The arti cles were more in depth and In 2010 the editor of Mech was LT David Robb. Prior to then, the magazine was edited mostly by civilians. The maga zine took on an entirely new red banner to signify the impor tance of aviation maintenance safety. By 2013-15 the magazine took on another slight change in look and staff. John Williams, the visual information special ist was the sole staff member until Nika Glover, the editor, came on board in 2015. The magazine featured full color pages with numerous photos to go with the articles. Most of the articles were personal accounts of sometimes har rowing and life-saving events. In 2016 Mech was merged with Approach so that it would ben The magazine was cut in half with Mech conitnuing to focus on maintenance related safety subject matter. The magazine will go completely digital in March 2017. By 2018 the mag azine will be fully merged with the other Naval Safety Centers publications.
