I have owned a PC 12 for 20 years and it has been basically bulletproof. However one of the best pieces of advice I ever received at SimCom was “when in doubt, there is NO doubt”. Immediately on NG rollback cycle the PCL once to confirm rollback and then engage the MOR (it is the only thing left to do before feathering the prop) and fly directly to nearest airport and land. Figure it out on the ground. Having said that I still think this pilot would have been fine if he didn’t drop the gear so soon - the PC 12 drops like a rock with gear down and no power. Thankfully he survived and hopefully he will make a full recovery and be flying again soon. Another off topic tidbit is one time we clipped a bird on rotation with the right AOA gage, bending it upwards to indicate a very high angle of attack. If we were in a Max the pusher would have engaged but thankfully the Pilatus guys engineered the system so that both AOAs must agree before the pusher pushes you down. The stick shaker immediately came on but we just flew a normal pattern (shaking the entire time) and came back and landed and called maintenance.

After some analysis on the flight path, we came the conclusion that a successful off field landing would habe happened. The only way the damage to the nose, the tearing off of the wing, can be explained, is that the stick pusher did indeed push the nose down AFTER flaring and attempting a nose up landing. The recommendation is that 🔥in case of a soft field landing the stick pusher must be turned off, overriding the stick pusher is possible, but only if one is prepared for it, not a time when the attention is outside to watch for ditches. Long experience landing on poorly maintained sand and soft fields in central Cameroon, where the nose gear should be held up for as long as possible, it was common to operate with the CG near the rear limit for exactly that reason. The normal procedure is to do a low level overflight to watch for depressions on the field.

Excellent job doing your research on the PC-12! I flew the PC-12 series 10 for a couple of years. The sim classes at that time were handled by Simcom. Most PC-12's do not use a Garmin flight deck (which is disappointing in my view). During my sim flight training (every 6 to 12 months), we used the Manual Override Lever when the pilot saw an uncommanded decrease in power (Ng). If you were not quick to apply the Manual Override Lever, you could lose the turbine power. Below 50% Ng you can get a compressor stall, then having to do a re-start. In the sim, we would practice multiple engine failures primarily on takeoff... usually at 600-800ft AGL, no time to think, so reactions have to be instinctual. So the procedure was, if the pilot noticed a decreasing Ng, we were taught to immediately use the Manual Override. If that didn't stabilize or increase the power, we would immediately feather the prop, push the nose over to best glide. In the case of a takeoff engine failure, I could turn the plane at nearly a 45 degree bank, keeping the airspeed just above stall and return to the airport. Almost every time it was successful (didn't want to tempt fate in the real plane). The key to extending the PC-12 glide was feathering the prop... it is a huge drag on that aircraft. As you said, in actual flight training we never used the Manual Override as it could cause severe damage to the engine. Keep up the good entertainment and work!

wow, must have been a maint issue, as far as i know it's one of the safest air frames out there, especially flying in to "to hell you ride" , since it was loss of power I can only surmise the pilot killed the fuel accidentally , or a mechanical or fueling issue..but that remains to be seen, too bad it's just spare parts. I've spoken to a pc12 pilot (one runs commuters to Toronto from here in Niagara very economically ), he has total confidence in the air aircraft . At this point we can only speculate what went wrong, but at least the pilot survived, and the fuselage seems pretty much intact..

@@blancolirio Juan, watching the video back now, I would like to address the comment you made about practicing the use of the MOR. Something unique to Boutique is that all initial and recurrent training is done in the actual airplane. To my knowledge, the company has never sent pilots to a full simulator training course. And just like you said, using the MOR in the actual airplane would never be done.
@gregthompson6489

You can NOT turn off the fuel inadvertently in a PC-12. It requires a very definite, and totally separate set of movements. A small latch must be released, and then a large handle must be raised 90 degrees. This handle is mounted on the aft of the pedestal, and pilots have no reason to ever use it, except in situations like this. It certainly wouldn’t happen in a mindless, automatic fashion. Also, if it had been fuel related, he would have a fuel low press CAWS message, along with a master caution, and would be in no doubt as to what was happening. This gets back to flying the aeroplane and running the emergency checklist.

@@Jordandelara Many PC-12 operators use the MOR in flight during training events. Pilatus has no limitation against this. I'm actually surprised that Boutique Air would not do this during training events if you aren't using the simulator. So your first experience with the MOR lever is during an actual emergency? That's crazy.

Juan as always great job! Always told my pilots that in the event of an emergency caused by an aircraft component failure, never factor in the idea of trying to "save" the aircraft in your decision making. The aircraft has already failed you and deserves to die - you don't! Besides, if you have to sacrifice the aircraft to protect yourself, you will be rewarded with a new and hopefully better aircraft!

Phil D ..I agree. As an owner/pilot of the PC 12 I find this baffling. I can go into the details of why he shouldn’t have been fooling around with this airplane and a possible faulty FCU, but I think it’s self explanatory to most people here. Sounds to me like he was more worried about what his employer might say, a schedule setback or facilities equipped to do repairs/maintenance on the aircraft. Now, I can promise you his employer is “somewhat” more angry, there isn’t a schedule at all anymore and there isn’t a repair facility in the world that can solve his issue. THREE MILES from a perfectly good runway with a fluctuating NG and he decides to go THIRTY MILES. End of conversation with zero excuses.

His choice of heading back to DFW brought back the old adage one is taught when first flying twin engines a/c. "When you lose one engine, the second will just barely get you to the scene of the crash".... When things start to go back with an engine... take the first alternate and let the mechanic put his tools in a truck.
@flymoyer3802
@flymoyer3802 4 роки тому
As others have stated, he said I have pumps on and ignition on. Having worked on PC12s for a few years, I have operated the MOR lever to do standard maintenance checks. The important thing is to move it slowly because you’re bypassing the FCU. The maintenance check was to keep the PCL at idle and move the MOR slowly to max and make sure the engine temperature, speed, and torque did not exceed the limits. Even though the PT6 is a reliable engine, when they fail it’s usually the compressor/turbine or FCU. In a single engine airplane, engine trouble means land now; in a multi engine airplane, engine trouble means land soon (there are exceptions).

Juan, this was a very good presentation. I'm a turboprop pilot myself, but with two engines (PW-127). I agree with your comment about never turning away from the landing spot. As a former glider pilot, I like to practice dead stick landings in the simulator when we have extra time left after the session. If I'm too high, I have several options: Extend the downwind, extend the base leg, make S-turns on final, use flaps and gear as airbrake, etc.

Lot's of lessons to be learned from this crash. This indecision toward diverting once the problem first appeared is something we have to fight constantly within ourselves. Same way, no need to pass all those infos to ATC (who did a great job, by the way). It is procedural. Even on our heavies we shouldn't wonder around when one of our engines start to play funny. Imagine that on a single engine aircraft... As pilots say back in Brazil, "quem tem duas, tem uma; quem tem uma, não tem nenhuma", or, in a direct translation from portuguese "who has two, got one; who has one, got none". Although I have some experience flying at night and IMC on a single engine myself and feel very comfortable doing it, it of course requires a quick response once things get weird, and I have my share of stories to tell. Great video by VASA and an excellent job by you again. Easy said than done, the engineers saved another pilot. But a lesson to be learned by us all. The PC12 pilot, to who we wish a quick and complete recover, for sure have learned.

"...LAND AS SOON AS PRACTICAL/POSSIBLE." The day I had an engine fire in a Navajo, I asked for vectors to the closest airport with a 3000 ft runway. It was a successful outcome, but I was strongly criticized by management for not flying an additional 7 miles back to the home (maintenance) airport. That's the short version. Here are some more details: I departed TEB about 10am local on an IFR cargo flight to Detroit. Climbing through 5,000 ft, IMC, we were in contact with NY departure and at that time of day it is like a very busy party line - everybody wants something from ATC. Then my copilot said, "Hey Mike, we've got an engine fire on the right side!" I looked out and sure enough - orange flames coming out of every opening of the nacelle. IDENTIFY (yeah it's that one over there with all the flames), VERIFY (it's still the one burning) SECURE. I did that too, throttle idle, mixture to cutoff, prop to feather, boost pump off, cowl flap closed. I had the copilot tell NY we had an emergency. When he did that, the party line went instantly silent and a different voice came on from ATC, "What is the nature of your emergency and what services do you require?" We answered the question and requested vectors to the closest suitable airport and a descent. "Turn right to heading 010, Morristown will be 12 o'clock and 3 miles. Descend and maintain 1,500; you are cleared to land any runway...." Then he gave us the surface wind MMU altimeter setting and the tower frequency - "contact them if able, but you are cleared to land." The rest was just like all the training flights we all have done, landing safely. I was really impressed with how all the other pilots went radio silent, and the professional handling by New York departure. I could not have asked for better service than what we got that day. Hats Off to NY ATC!!

Guy didn't take him up on the offer or mention it again..in that case it was handling a soon to fail engine. Anybody complaining about landing at nearest location after any in flight fire not the result of being shot at shouldn't be in aviation, in my opinion.

Ng is the gas generator RPM (in percent) in the PT-6 (analogous to N2 in a single shaft engine). The PT-6 is a free air turbine engine and uses concentric shafts. The expanding gases from the gas generator turn a separate turbine that powers the propeller through a gearbox. Primary power setting indication is torque. The PT-6 engines are very reliable and rarely fail. If you have a PT-6 starting to fail like in this case, it should be approached as a land as soon as possible. Easy for me to say but it is unfortunate he talked himself out of landing at Rockwall only 3 miles away. As it turned out he might have completed that landing before the engine completely failed.

Covering the chapter 3.4.4. of the emergency procedures, Juan was surprised about the instruction to "land as soon as practical", and so was I. Apparently, Pilatus judges a partial loss of power as a situation where they leave the impact of the power reduction and the risk calculation up to the pic...either land as soon as practical or escalate to as soon as possible...depending on what? The analytical talent of the pilot in an emergency situation and doing the 100% correct risk assessment? Later, and that part of the checklist wasn't discussed in the video, chapter 3.6.11 covering Engine NG, step 4 clearly states "land as soon as possible"....which, in this case, was the problem and the only right thing to do.

I know accident reviews are about learning rather than blame, but this was just horrible airmanship. Bad decisions, waffling over RT instead of flying the aircraft, and then the stall is just unforgivable. We train for this. We practise this. A lot. You basically have one job to do with engine out on a single - pitch down for your required airspeed and stick on it. Pitching up thinking it will take you further is the action of someone who has never had any training.

Gianni Dameno S1nglengine Except it isn’t. Ng is NOT the primary engine instrument to set or measure power output in a turboprop. Torque is used to set and measure power in a turboprop and is most analogous to N1. Ng is analogous to N2, the core of the engine, the section that is the gas generator.

I was certified as an AV8B engine operator. We had to demonstrate “Manual Fuel Operation”. You essentially shut off the fuel control unit then controlled fuel to the engine with a hand throttle. First action turn the igniters on . Then move the manual fuel lever VERY carefully ! This is only performed to verify “Manual Fuel” functionality. Incorrectly done you could severely damage or scrap the engine. “Manual Fuel” was the pilot’s last chance to keep the engine operating. The AV8B is a single engine jet ground attack aircraft.

Such a good, detailed analysis based on what can be known so far. I had my engine oil temp redline in unfamiliar airspace and a lot goes through your mind. I asked the controller for vectors to the nearest airport with maintenance facilities. He sent me to a rural airport that had no repair facilities, plus the runway had workers on the last 1/3rd of the runway. Very challenging, but I was able to land and call my mechanic. It will be interesting to hear from this pilot as to what happened.

Thanks Juan, great summary as usual and look forward to more info when it’s released! The PT6 is usually a pretty reliable beast unless mistreated- I have about 1800 odd hours on PT6A-42’s (Cheyenne III). Glad you’re teaching your son the right things to do: When I had 2 hours flight time, it was always “Aviate, Navigate, Communicate”. With 28,000+ hours in everything up to and including 747-400’s, it’s STILL “Aviate, Navigate, Communicate”! And WOW 😮 , that PC12 stall, don’t think I ever flew anything with a stall as nasty as that!

If Bob Hoover could do it, so could anybody crazy enough, with a malfunctioning engine, to fly away from a first suitable landing field.

The PT-6 is flatlined at 1700 RPM prop speed when flying. Only the prop AoA adjusts the power when flying. So losing NG is a direct loss of propulsion force equivalent to that indicated on the instrument.

Besides, there are some accidents in which there are lessons that are pretty obvious, pretty quickly. This is such an accident. I am sure that the NTSB will figure out why that PT6 failed, but pilots care more about how the situation should be handled when it happens. Great research, great presentation. Thank you!

Young or inexperienced pilots will often talk their way thru an emergency. My belief is he is thinking out loud, and venting stress. I try not to be too hard on a pilot after their first engine loss. His adrenaline rush was probably massive which hinders the logic function of his brain. This is a physiological limitation and will become manageable with time. The company may need to rethink their training..... Just a thought.

Exactly what I thought. Adrenaline. I remember Al Haynes from United and the Sioux City Crash came to our Commuter company to talk with the pilots about how to handle emergencies and what he learned and he passed that information to us and I never forgot it. He said, "never raise your voice and get excited, talk your way through the emergency, because if you raise your voice the other pilots will ramp up their adrenaline and you will make mistakes, stay calm and live and work together". This is kind of what this channel is like too. So many pilots and thousands of hours of been there, done that. It is refreshing to see the positive comments.

The PT-6 FCU is an old, totally mechanical unit. As a pilot we control the FCU governor (a speeder spring and few fly weights, same as a prop gov). We simply set the desired NG (compressor rpm, this is a free turbine so we also have prop rpm NP). The FCU governor opens (for more rpm-fuel-power) or closes (less rpm-fuel-power) the fuel valve. Once desired rpm-fuel-power is achieved the fuel valve "floats" and maintains proper fuel flow to maintain desired NG (on speed condition). The fuel valve is moved by P3, bleed air from the compressor that is then reduced (Px and Py within the FCU). If you loose air (for whatever reason) the fuel valve goes to a mechanical stop (called min fuel, same as on any carburetor), the engine becomes unresponsive to power lever inputs and the engine will idle. This happens at times when the mechanics forget to connect the P3 line after compressor wash (the line is disconnected so no water gets inside the FCU pneumatic side. The manual control lever allows the pilot to directly move the fuel valve, it is that simple. Only single engine installations typically get this manual control, Cessna Caravan for example. The FCU governor along with the pneumatic side (Px and Py) provides some acceleration/anti compressor stall/ITT protection but especially starting from idle on a PT-6 a gentle hand is required. There is no modern day "full automatic" anything within that FCU. Bunch of springs, bellows and some old fashion mechanical stuff only. Here are some NG numbers for a PT-6 27 (I fly twin otters) 46% this is min fuel stop, FCU governor not working or no Px-Py 50% FCU governed idle, fuel valve in the floating position 85% compressor utilizes both axial and centrifugal design, there is a bleed valve that is open at low rpm, the axial portion pumps too much air at these low rpm, at 85% the centrifugal is ready for all of it 97% sea level, warm day full power 94% typical cruise power at 8000 warm day Last point, power is set by prop torque TQ reading. For me it is 50 psi, based on the air density I get that 50 TQ at different NG values. As stated earlier I control the FCU governor RPM but my power indication is the prop TQ value. So many guys that I fly with (lost of low time co pilots) are not very interested with the NG and only look at the TQ values. This is the same as if you were looking at what the tires are doing in your car while dealing with engine issues. This pilot here did well by reporting NG and not loss of TQ. On the other hand I don't think ATC knows much about NG. This might be way more then anyone wanted to know, but I am stuck home and can't fly so here it is. Thx

That encompasses the outstanding, life-saving priorities you have wisely instilled in your son: Aviate, Navigate, and Communicate. Keep up the good work, Brother!

I am a Pilatus pilot and the first thing I noticed was that this guy NEVER DECLARED AN EMERGENCY! By not declaring an emergency, none of the air traffic controllers took his problem seriously. Also, I also noticed there was a complete lack of critical decision making, such as putting the gear down before he had the field made, and landing on runway 18, circling to lose altitude and landing down wind. He had plenty of altitude to make a normal pattern to 36. I am wondering if he ever feathered the propeller and if he used the fuel control manual override lever. The PC-12 is a very easy airplane to fly and glides forever, but only if the prop is feathered.

At that point he may not have had the altitude to do a normal downwind for 36 so choosing 18 was a surer bet.

Couple suggestions for pc 12 pilots now that I'm successfully retired from them: I was a pilot doing the data gathering test flights (in the real plane) for making the FS NG sim. We did stalls with a disabled pusher. With no flaps it stalled like a Cherokee and was a non event. With full flaps, a wing dropped very suddenly and quickly. Instead of trying to roll it back, it was actually faster to just help it do a full roll. I am not suggesting it though. Both cases are obviously bad news close to the ground. With enough altitude, not a big deal, but the pc12 would have a lot of roll "inertia" from the sudden snap and would end up rolling to pretty much 90 degree bank before it would stop and reverse the other way. Long story short, don't fight the pusher. I have flown with people that said they would hit the pusher override on a landing stall. Very bad idea unless you're 3 feet off the ground. The MOR lever. I suggest practicing in the plane, it's not as big of a deal as some make it out to be. Yes, it can do damage if you are careless, but it's also not as touchy as some make it out to be. In a real world emergency, even if you overdo it and overtemp, just pull it back some and try again slower. Unless you leave it full blast, the engine won't instantly turn into a puff of smoke like in the sim. Better know what to expect in the real world. For practice, pull the power back to half or so (to keep NG high and safe) and try out the MOR. Feels more responsive and direct with it. Don't get too overly confident in the single engine pt6. The engine out climb is terrible. Be paranoid and have a plan. I've had 2 pt6 issues before. I was always lucky that I was not far from landing. I enjoyed the pc12 but I'm glad to be out of them. Felt like my single engine luck was going to run out sooner or later. Edit - Found some old footage of the no pusher stalls. Some stuff was purposely omitted to not give out bad ideas. ukposts.info/have/v-deo/bXOJd6aAsW6Q058.html

The Cessna Grand Caravan has the PT6-114 turbine producing 675 shp, roughly half the larger turbine PT6 in the Pilatus PC12. Flight Safety covers the FCU failure due to loss of Py suction to the FCU and subsequent loss of torque. The best indicator of this is the Ng gage which will drop as low as 48%. Federal Express Feeder does not practice in the actual aircraft in flight. Sim only. I know a pilot who tried MOR in a Caravan out of curiosity and destroyed the PT6-114 turbine because of no FCU protection. Maybe the PC12 MOR is less sensitive? Juan correctly covers these issues in the presentation. You have to be well rehearsed mentally to catch a loss of suction and implement the MOR soon enough.
@extraace
@extraace 4 роки тому
I’ve never tried it in the caravan. Pretty much the same fuel controller isn’t it? It’s been a long time for me since the 208. I could see jabbing it forward though once the safety wire breaks if they’re still like that? Pilot of a pc12 operation I used to work at had a bellows failure and a roll back to idle. This was an early pc12 with the old style bellows. He said it was not much of an issue but he was in cruise with plenty of time to not rush. He was the one that trained me in a pc12 when I first started and had me practice it in the plane. Fast forward to the sim data gathering - we did multiple scenarios with the MOR lever. Sim should be based off that unless they ended up using some other data for it. I never had anything iffy happen while doing it. Just mimic the fuel rate increase of the fcu. Same thing just no protection.

The PC12 is perfectly flyable using the MOR lever without risking damage to the FCU.

The USAF has us fly full patterns on the MOR to get used to the lag with power adjustments, but again, totally flyable.

Hoping your engine holds together for another 30 miles is a gamble I wouldn't be taking. The pilot passed on the airport he was first vectored to. Why not be on the ground and sort the engine malfunction than continue on? The second situation was descending to early. Altitude is insurance in the bank. Then the final error was not flying over the runway and then lowering your gear too soon. Seems odd to be operating such a high performance aircraft and make these three vital errors. Never fly over a good runway when you have engine problems especially single engine .....
