Stig Shift #29 (Aircraft Maintenance Adventures)

[@Pupda]

Since Stig asked (12:45), from the A32F Quick Reference Handbook: Engine Relight (In Flight) 1. Maximum altitude .................................................................. Establish 2. ENG MASTER______ ............ Confirm ........................................OFF 3. THR LEVER______ ................ Confirm .......................................IDLE 4. ENG MODE....................................................................................IGN 5. X BLEED ....................................................................................OPEN 6. WING ANTI ICE (for starter assist) ...............................................OFF 7. ENG MASTER (affected engine) ....................................................ON 8. Engine Parameters (N2, EGT) .................................................Monitor [Engine light up should be achieved within 30 seconds after fuel flow increases.] In the actual QRH between steps 1 & 2 there is a set of four charts that show the required altitude and speed envelopes for the various engine types. Very generally, for a windmilling start the plane must be below ~27,000 ft for CFMs - slightly higher for IAE engines; and above 190 kts for CFMs, 220 kts for IAEs, and 230 kts for NEOs. This means if we're up at typical cruising altitudes in the 30s, we'll be descending for a little while before we can even think about an air start. On the other hand, if we have an air source available (APU or the other engine) the envelope is considerably wider; that's covered by step 1, and also generates step 5 which tells us to open the crossbleed valve (if the APU is available, the crossbleed valve would open automatically but by procedure we open it manually anyway). But in the case where the start valve has been deferred, that obviously wouldn't come into play. Also note that with the exception of step 6, there's no procedural difference between a starter-assisted restart and a windmilling restart (including one where the start valve is inoperative); the checklist is designed to be simple and quick, with a minimum of "if/then" steps. Steps 2 & 3 simply make sure that the engine is secured off before we attempt the restart; in particular step 3 is important because in the case of an air start, the engine will accelerate immediately to wherever the thrust lever is set, and that can be pretty exciting if that's not at idle. Step 4 ensures that both ignition systems are on line continuously for the restart; on a normal start only one is on line, and that comes on automatically at a specific point in the start sequence (based on N2 or core rotation speed) and turns itself off when the start is complete; on an air start we just turn on everything continuously. BTW fun fact (sort of): the IGN position is actually labeled "IGN START" and is the same position used on the ground for a normal start, which helps keep this procedurally close to a regular engine start; in the heat of battle, habit and simplicity are strengths. In fact, steps 2, 3, 4, 7, & 8 are the normal Airbus start on the ground. Consistency is a good thing. Step 5 ensures we have an air source available for a starter-assist restart attempt; as mentioned, if the APU is available and on line, it would open the crossbleed automatically but by procedure we just open it anyway. An important side note is that we're restricted from using the APU bleed air until below 20,000 ft, and in the real world I can't imagine any pilot is going to wait and descend that long before attempting a restart, which practically speaking means that we'll always attempt restarts using bleed air from the other engine - hence, the crossbleed valve must be manually opened. Step 6 turns off the anti ice system momentarily and routes more bleed air to the starter to maximize the chances of getting the engine restarted. While we never want to turn off the anti ice system if it's in use (wing anti ice is actually used relatively rarely) we can afford the tradeoff for a minute or so if it ensures we get the engine restarted. Step 7 restarts the engine...hopefully. Otherwise a bad day just got a lot worse. After that it's hopefully just clean up. Hopefully. P.S. One last fun fact - notice on steps 2 & 3 the word "Confirm" - that's really important. In an emergency one pilot - normally the first officer - flies the plane and communicates with ATC while the other pilot - usually the captain - runs the checklists, coordinates with dispatch and crash/fire/rescue, checks with the cabin crew, speaks to the passengers, decides on diversions, etc. That pilot will recite and perform the emergency checklists out loud so that the flying pilot remains in the loop, but basically works through the emergency procedures on his own. The exceptions are steps labeled with the word "Confirm"; in this case the flying pilot must literally confirm that the monitoring/troubleshooting pilot has his hand on the correct control/switch/button before operating it. It's really bad form to lose an engine and then accidentally shut down the good engine. Hence, "Confirm".

[@StigAviation]

You never disappoint my friend. Thank you so much. Gonna pin 📍 this so people learn from a professional 🤙

[@EstorilEm]

Great information, thanks! ...and yes, that "bad form" has happened many times, the TransAsia ATR-72 comes to mind as the most blatant example, though.

[@Pupda]

​@@EstorilEm - absolutely; that video of the ATR rolling over as it crosses the bridge is just horrifying. The "confirm" step is a big deal; as I mentioned, normally the non-flying (or monitoring pilot) does all the emergency checklists, with the flying pilot confirming the actions as necessary. There is one big exception at our airline and that's the thrust lever in step 3. Whenever an emergency checklist calls for adjusting the thrust lever (usually to idle, as in the above example), instead of the monitoring pilot, it's the flying pilot that places his hand on the thrust lever, the non-flying/monitoring pilot confirms it's the correct thrust lever, and then the flying pilot pulls it back to idle. This way, even if for some reason they've selected and confirmed the wrong thrust lever, the flying pilot will immediately sense the loss of thrust and/or yaw and push the thrust lever back up to where it was. It's one last barrier to doing something stupid and potentially tragic. It might have saved TransAvia 235.

@@StigAviation - Omigod - To be in the same category as cargo...my life is complete! Your channel is a treasure - it demonstrates how complex but well-thought-out aviation is, and how much effort we put into it to keeping the airplanes running - particularly maintenance, but also pilots and even our ground crews. Sometimes the things you talk about kind of lend themselves to discussion on how or why they are the way they are from the other side of the cockpit door; this was one of those things - plus, you asked.😉 And in this case, in real life I had asked myself that same question years ago about what we would do if the engine flamed out at altitude - it's a good question. A really good question. Anyway, thanks for the kind words, and for all you do, both on the line, and also online.

So rare these days for big corps to be so chill with all the millions of dollars of HR, PR, lawyers etc and just let an employee post stuff like this. You couldn't pay for better advertising, seeing Stig's passion and proficiency makes me want to fly on American.

[@ronaldjames]

That’s very true.

[@StigAviation]

Well here’s the thing. I don’t represent my carrier. I represent aircraft maintenance. My employer does not encourage me nor discourage me, but they are always watching. I do per procedure and per social media policies. To stay within legality of what I do. But anything I do is pure information for aircraft and aircraft maintenance, which is already public knowledge. I do this because I love to teach and I do this because I love to talk to people, my passion is my work, and my work is my passion. I love this job, it’s the best thing in the world for me. I hope and pray that I can keep on doing this, I am just very thankful for the opportunities that I have and the fact that I can share my life and adventures with all you beautiful people.

@@StigAviation you say you don't represent your carrier, but you kinda sorta do either way and you do it well!

Wow, thank you Stig. Another week and yet another brilliantly perfect video. I'm genuinely at a loss as to how they're getting better and better each week!!? I know I've said all this before, but it really is getting quite unnerving how you keep raising the bar, I don't know what type of sorcery you're using, but please don't ever stop using it!! The explanation of the hydraulic isolation was brilliant and just the level of technicality we all love your videos for. The awesome explanations of systems at the level you give us is spot on, you explain it really well so we can have a good understanding of how the systems work without obviously having any training or manuals etc etc. I think we all love your channel so much because of this, I think we're all here, not only for the "what" a system and it's function is but also because we love to know the "how" the system works and you show us that brilliantly. Awesome job Stig and thank you once again, sincerely. I totally agree with you about the ghost part, too. I once worked nights in a building where somebody had passed away, and it was well known by all of us that "things" would happen and happen they surely did!!

[@legit.peasant]

Honestly, I don't mind the Brake Rides! I think it's a nice opportunity to drink in how an airport runs like a well oiled machine, thousands of tons of metal moving in one majestic dance as they go from place to place. I must though, admit there is something really eerie about an empty plane... it has the liminal space feeling of "something doesn't feel right..." That Ghost story was something too... I've never had an experience like that, but I know sometime after one of my Grandads passed away I was at home with the family; and I had this feeling as if someone had gently placed their hand on my shoulder, but when I turned around there was nobody there. It wasn't cold or anything like that, just as if someone gently put their hand on my shoulder... I've had this happen to me twice since he died, in a very short space of time too. He was a Spiritualist, and I'm very much a "nothing is impossible" kind of person, so I'm open to believing it was him. Some things in life are hard to explain... Great video as always Stig, looking forward to next week!

[@StigAviation]

I am very happy you enjoyed it all, and thank you so much for sharing your experience with me as well.

[@Kodiak31415]

13:00 Engine technology these days is so advanced that if FADEC/EEC can't save an engine from shutting down in flight the engine is probably damaged to the point where we aren't going to be able to re-start it. There are only a few oddball scenarios like a heavy volcanic ash encounter, extreme amounts of precipitation ingestion, or sustained flight at high altitude and AoA, that could cause an engine to flame out in a way where it could be restarted later. In the event that the starter valve is on MEL, or if there's no source of high pressure air, the procedure is to fly fast enough that the ram air windmills the n2 spool up to an RPM high enough to try a relight. If you read the CVR transcript from US Airways 1549, the plane that landed in the Hudson, there's a bit where they discuss the minimum speed for trying to restart their engines.

[@StigAviation]

And you are absolutely correct on this. It’s such a rare thing to occur. The efficiency level of these engines is mind blowing. To a point where the engine will literally restart itself without any input at all. But as you said, it’s a very oddball scenario, which will 99% never happened.

[@sharoncassell5273]

Pax just sit down and relax. I see them go to sleep prior to take off. I at least read the safety card and demo. Look out the window.

[@W7LDT]

During my airline career I flew Airbus A319/320/321, B737, 757,767,777. It amazes me how you retain such a detailed level of knowledge about all of them. I only had to remember one airplane at a time.

[@StigAviation]

It’s definitely a daunting and challenging task to stay up-to-date on all these fleet types. But I enjoy it very much.

[@SimonBillingham-zq4oy]

Another informative episode, some trivia for you. The A330 MRTT (inflight refuler) uses the location for a A340 engine to mount the droge refueling pods to the A300 ( the wing is the same as well as the fuselage). In the 1980’s it was a normal practice on P&W JT9D (747) to trim the engine manually while at idle with cowels removed, saves time by not shutting the engine down, lots of fun holding your arm through the cold stream and adjusting the FCU which was notoriously sloppy when being adjusted, 2 clicks required, move 2 clicks, no change, move one more click, effect on parameters 4 clicks, very fiddley. Like seeing the 787 stuff, never got to work on them even though they were in the QF fleet. Well done.

[@StigAviation]

Thank you so much for this incredibly well described information. I appreciate you Simon.

[@EstorilEm]

Lol I mentioned this above, didn't see your post - the pylon locations indeed have the inherent strengthening for the outboard engines there, great idea by Airbus to create the commonality in the first place (probably long before thoughts of a military tanker were conjured up) and even better execution afterwards. Especially in the context of an insanely over-budget and delayed "simply modification of a 767" in the KC-47. That contract (ironically) was won by the Airbus MRTT, but of course Boeing filed an official complaint and magically won - so here we are lol.

[@REstrACIA]

It's kind of cool to see the turbine blades match the framerate of your camera, then oscillate as it hits inflection points. Love the engine shutdown clips.

[@marshmellow377]

If the starter is inop and we have an engine failure in flight, you would look at the starter assist/airstart graph, determine which window you are in based on altitude/speed and either descend/climb or speed up/slow down to fit within the airstart (windmill start) window. Then you would follow the normal start procedure just using the relative wind to spin the turbine rather than the starter itself.

Hi, Stig! I've been watching your videos for quite a while (I'm 4th year student in university studying aircraft maintenance and repair). Yesterday was my first day in full-scale practice in LED in Ural Airlines. I cannot describe how your videos helped me to understand what it all REALLY about. Of course, your vids are not AMM and ref only, but being familiar with works on real plane really helps. Today I wasn't scared of aircraft, and did some minor works (under supervision, of course), and it was fantastic! I'm huge aviation fun in general, but being a part of process of making aircraft airworthy - it's just unbelievable thanks a lot for your videos, really appreciate it looking forward to some A-checks and 10-days-checks, it must be super interesting

But the A340-500 and 600 are the REAL BEASTS of an Aircraft!! And even if the smallest variant A350 variant, the A350-900 was meant to replace the A343, it still feels like a BEAST compared to a 343, and the A350-900 also replaces the A340-500 as well, most especially with the 900ULR variant owned by Singapore Airlines! And that A350-1000 in your last video before this one BTW, is TRULY A BEAST, with an identical size to a 777-300ER!!

When you were talking about standing next to a running engine it reminded me of my dad telling me when they were doing high power engine runs on the EE Lightnings they actually had to wear a form of body armour/chest protection as those engines could actually cause significant internal injuries when the reheats were engaged. I would absolutely love to experience that. I've stood at the wing tip of a Spitfire during a high power run, and that was brutal enough, and that was a piston engine. Granted, not "just" any piston engine but arguably the greatest piston engine ever. I'm sure I don't need to mention the name... But standing 20 feet away from a 24 litre V12 with 3-inch exhaust pipes running at high power was absolutely awesome!!

[@KevWitt3455]

It's staggeringly awesome, isn't it!! I think a lot of people don't really understand as they understand power through HP, for example, and you can't really convert thrust to hp as you're well aware.

If I had to guess, Rheinmetall made an air start cart for military applications like C-5s or C-17s or A400s, and then they realized “Huh there is a large civilian market here” and repurposed the military cart to be one for civilian use. That, or some engineer got really bored one day and designed a really good air start cart.

@13:30 I whipped out the Airbus relight checklist for grins. Very broadly speaking as it's a convoluted graph, the CFM56 can do an unassisted start at or above 180kts, the LEAP and IAEs at around 220-230. All need to have it done below 20k ft, above that, they need an APU assist, so the plane in this case wouldn't have been able to do so if need be unless they descended, at which point they probably would be doing so regardless. Then: Eng master... off THR lever.. idle ENG Mode.. IGN X bleed... open Wing anti-ice (if using starter assist).... off ENG master (affected engine)... on If relight succesful: ENG mode.. Norm Tcas mode... TA/RA (because it would've been set to TA only to avoid distraction in the ENG FAIL checklist done prior to the relight) X Bleed... Auto Affected systems... restore And bobs your uncle... otherwise... if the relight failed... ENG Master... off... Either outcome dictates an immediate landing for obvious reasons. Nice video as always. Take care

[@Pupda]

Nope, other way around on the APU - the APU is restricted to 20,000 ft and below for bleed air, so there's NO APU assist above 20,000 ft, only below 20,000 ft. The "Starter Assisted Relight" section of the charts is for any air source - APU or the other engine via the crossbleed line (hence the step where we open the crossbleed valve - it would open automatically if the APU bleed was on line). Practically speaking a "Starter Assisted Relight" will always be a crossbleed start unless you've lost both engines, and you then descend below 20,000 ft and get the APU on line. And if you actually look at the charts, you'll see that you can do either a starter-assisted crossbleed (or if below 20,000 ft, APU bleed) restart or a windmilling restart at any altitude up to the maximum restart altitude for that engine type - CFM, IAE, LEAP; you just need to meet the speed requirement for that altitude, which will always be higher for a windmilling restart. P.S. TCAS isn't set to TA "to avoid distractions" - it's actually a little scary if you think that's what's going on. In TA you'll still get all the TA calls, which practically speaking means you'll get all the normal calls (i.e. "distractions") since RA calls are rare, and in any case in TA mode they become TAs as well. We select TA because the plane will almost certainly not have the performance to meet a climbing RA and will in no way be able to meet an Increase Climb RA*. Hence we select TA and that tells any other TCAS that is coordinating an RA with us that our plane cannot meet RA requirements and the onus is thus on the other aircraft's TCAS to avoid us, as far as RA coordination is concerned; of course, collision avoidance is always on us as well, just not as far as RAs go. Not hitting another aircraft is far more important than "distractions". * From the A 32F systems manual: - TA: Can be selected by: • The crew, on the ATC/TCAS panel in case of aircraft degraded performance (engine failure, landing gear extended), or when operating near closely spaced parallel runways, or • Automatically, if TA/RA is previously selected and: - The windshear (as installed) message is triggered, or - The stall message is triggered, or - GPWS messages are triggered, or - Aircraft is below 1000 ft AGL.

[@aerialbugsmasher]

@@Pupda slow night at the schoolhouse huh? Again, I said very broadly speaking. Everybody's first instinct would be to power up the apu with a failure so you could assume that would be a likely source. But I don't think the laymen need us to get too deep into the weeds here. And it was a CKA that told me the TA thing in a nutshell But yes good points you bring up.

[@StigAviation]

Thank you so much for this detailed information. I just saw it, there was another pilot that wrote the procedure, which I pinned. Many many thanks for this.

[@EstorilEm]

A330s are one of the most graceful aircraft out there - the smaller engines (relatively speaking, compared to the 777s we're used to now) just make the wing look even larger, though the A330s do have a low wing loading already. They're notorious for floating on landing, just want to keep flying lol. The downward camber at the wing root (when viewed from behind) is also BEAUTIFUL and unique to Airbus (at least their wide-bodies, 380's have this also). I wish the 330 NEO was more popular, but they're doing well (understatement) with the 350, so it's understandable. That's a tough sell with the efficiency of the composite widebodies, but they're still being sold at a relative bargain in comparison - if you've got fleet commonality, it's a great idea IMO.

[@StigAviation]

Very well said. 👌. Also from what I understand the 330 Neo wing design is the most efficient design in regards to aerodynamics. A beautiful aircraft

[@EstorilEm]

@@StigAviation I've heard that too, and it was already a good match to the fuselage (why it didn't need the larger engines). Boeing got themselves into somewhat of a conundrum when they decided to stretch the 777 with the LR/ER, the wing was simply too small for the weight, and massive engines were the only real solution (not just a matter of single engine performance on takeoff.) They apparently have some strange performance issues at MTOW during the initial flight legs, but maybe a 777 pilot can elaborate further. From what I understand, the wing on the 330 has always been relatively large (maybe another result of the commonality with the 340 production?) and it performs very different. Also a cool thing about the 330 is that the interior structures for the outboard engines are somewhat retained in the 330 wing (at least the provisions for strengthening) which allowed them to rapidly develop and produce the MRTT / military tanker variant of the A330 - those same outboard pylon locations are used for additional retractable refueling probe stations on the wings. Sharing that wing/design between the two aircraft turned out to be a great idea. Oh and yeah, a 340-300 is REALLY rare! The 500/600's just look like a beast with four of those big high-bypass engines.

Nice touch with the spinning camera in the end, Stig! Speaking of which... Maybe... just maybe sometime... when you film those spool downs when your next office has parked... There are some of us geeky enough to appreciate to stick around until the fan blades comes to a complete stop. Hearing this clickety-clock when the blades moves at low speeds (depending on engine type that is) and then stop... mesmerizing! Just a humble.. wish. Thanks for top tier videos! Content wise as well as narration and editing!

Your ghost story at the end made the hair stand up on the back of my neck. It reminded me of a job I had years ago working in a small town medical clinic. I worked overnights and was the only one there, or so it seemed. But I’ll tell you there were many nights it felt as thought I was being watched, and that while making my rounds felt like I was being followed. It was definitely unnerving at first, but I quickly realized. Whatever or whoever was watching me, wasn’t there to harm me, maybe just curious. Anyway, another great Stig shift!

[@Driver-retired]

Stig as always another great lesson PS: at 14:07 your co-worker (near nose gear) gave you an OK to activate the valve. (half a second view (:-))) He needed to be in communication with flight deck for that to happen as they were ready for #2 engine start. And flight crew had the overhead man. start switched to on - then after N2 reached 20% fuel cut off is flipped up., and you are then ok's to close valve (you waved your arm to acknowledge that). Again flight deck and ground coordination is required - just an extra observation - Kudos to you for your always brilliant explanations.....just thought the the added detail might be helpful. Cheers......
