Sure. The main things to note are the blue dotted line is the #2 engine parameters that indicate the failure. ITT, Fuel Flow and Prop RPM all indicate reductions in values just past the 52:38 mark (obviously more than just those parameters, but those 3 are just easy to point out). At 52:53 you can see the first aft movement of the #1 power lever (PLA). At about 53:20, the #1 condition lever was moved to fuel shut off (Fuel SO). Conversely the #2 condition lever was never placed at Fuel SO.

Even though the #2 engine failed, it never did completely shut-down. If you follow the #1 parameters (of the mistaken shut down engine) compared to #2 you can see #2 oil pressure stays up, still some fuel flow, NH and NL etc. I can't figure out what the actual failure was- something weird goes on with the Torque parameter recording- that would be helpful to see. I don't know anything about the ATR600, so while I have an idea of what the #2 engine problem was, I can't be sure. Does anyone know if the 600 has FADEC?

Not sure if that makes any sense?

By the sounds of it, several of their pilots don't even know if the 600 has FADEC :roll:

That's great. Thanks.

What's with the crazy up down #2 torque numbers and then later the spastic oil pressure readings? Are those the kind of things the human eye just wouldn't see but a computer can graph or is it like a prop going in and out of feather as oil pressure rebounds and then plummets? Bootstrapping or hunting?

Maybe it's NTS'ing - but I know nothing about that engine type. Does it NTS? I imagine it has something similar?



In other news - half of Trans asias pilots have been suspended for either failing or not taking a proficiency test! Pretty scary.

On one of our phases of recurrent training we do run a scenario whereby weather is hot and lo and behold...incomplete ATPCS sequence so no feathering....guess what....it climbs...not spectacularly like it does here in the north this afternoon but it does climb!

So as has been stated previously, if they had done nothing at all they probably would have been hoisting drinks with the lads after work.

SLOW THE FUK DOWN....PLEASE!!!!

They help, but it depends entirely on how they're done. In most cases they are a compulsory set of words - uncorrelated to any actions - spewed forth by rote memory in microburst fashion. In my airline's case they are supposed to be done with PF/PM roles being played according to even/odd dates irrespective of who is even going to be flying the airplane that leg.

When I do them the correct PF/PM roles are played for the next takeoff, and we do them slowly and methodically while physically rehearsing the actual corresponding actions. In some rare cases even the simple change of cadence throws guys completely off and they have to struggle to remember the next step. I also don't mind interruptions and distractions while doing them as both will be a certainty in a real situation. They are done the way most guys do them as a matter of training and airline culture.

Approach briefings are another thing. Standard briefs as 99.9% of the guys give them are done with no actual thought put into them and sound just like the teacher in the Charlie Brown cartoons. Irrelevant stuff like published visibility are briefed because it's standard even when the reported visibility is 40nm, and relevant stuff like step-down altitudes, rates of descent, configuration planning, airspeed planning, terrain etc. etc. etc. are not mentioned because they aren't in the standard brief example. Might as well not say anything...

The fundamentals are obviously not there. I suppose as the latest group of pilots, pushed through training and stuffed in the right seat without ever having 'flown' a real airplane, which is not the process here in Canada, Our Hero starts to actually be expected to be a captain and actually take charge of the aircraft; the weaknesses in training and background are glaring.

"Dead leg dead engine - verify!"

I suppose that doesn't work if you don't know what the rudder is for and how it works. But what about all those silly gauges, that Master Warning making all that noise? Never heard that before? They tell us modern pilots are systems managers, if that's so, how come you got all the simple systems stuff so wrong?

I'd sure like to hear the (translation) of that CVR to hear what they were actually doing in there. All three of them. Hero, my ass.

Rant Switch .......OFF

So it all comes down to professionalism. If you are so bored in the cockpit, you have made that leg so many times, briefed that approach so often that you can't come up with any enthusiasm for the process, why are you there? Shouldn't that be a red flag to yourself that you need to examine what you're doing?

In my books, the good old “Dead Foot, Dead Engine” works. You can't go wrong. The plane yaws toward the dead engine. I learned that in a beaten up 150 HP Apache 40 years ago, like a bunch of us.

Why they didn’t do that drill is over my head. I know, I wasn’t in that cockpit but as Xs says above, we’re looking at the basics of multi-engine flying.

That darn rudder…does the average modern airline pilot has a perfect understanding of it? Can they all handle a 65 HP Luscombe in a light crosswind? Sad to say but I doubt it.

BUT… When you fly a Luscombe at gross weight, you have only one passenger at risk.

Exactly ettw;

Me thinks the first thing to control in the event of any emergency, flying or not, is ourself, then, the situation. It boils down to BE PREPARED.

Dead leg, dead engine only really works if you hold a constant heading. ie "step on the bug".

Set heading bug, and hold heading with rudder then it's a no brainer, and having pnf verify on the guages confirm the auto feather should just back it up? What I saw on tv, showed a nearly constantly changine heading. I'd bet it would be really easy to mis identify the failed stove while banking towards it...

I'm almost wondering if they thought they had a runaway condition on the left engine since the right engine still showed signs of ITT.

Fair point. Basically you really only learn one thing when you get your Multi Rating. And that's what you are going to do when that second engine fails and you're going 'back to single engine' flying. The interesting part here really is how a total of three experienced pilots didn't realize what was going on. I hope it's not another one of those hierarchy issues that seems to pretty common among asian crews where the less experienced are afraid of speaking up to the old experienced pilots. The CVR will hopefully give some more insight.

Regarding the dead leg - dead engine. How does that work when you're in an airliner that is being flown by the autopilot? I understand they were still pretty low and most likely hand flying but a little later and the autopilot would have had control of the airplane.

Would this be another case when auto pilot crashed the aircraft?

-- It does -- eventually -- and of course this varies with type but with some aircraft types such as a herc or anything else with an NTS system can actually fool you if you react too quickly - you will step on the wrong rudder which will put you into a flight regime that might not be recoverable --

Indeed it can -- good point -- I remember a check airman doing that to me - at V1 the engine went to firewall thrust -- took me completely by surprise and by the time we identified the problem cleaned up and did the drill the airspeed was in excess of 250kts -- a great lesson in flying the aircraft and modifying SOP's to deal with the situation ---

ATR release indicates an observer. Wonder if there was some unknown inter-personal dynamics at play that could help explain why 2 pilots could screw it up so badly.

I had an interesting discussion with a ATR 72-600 TRI/TRE who has as much experience on type as anyone flying the sub type. His thoughts ran to the warning messages. He mentioned you will get messages in an order like Torque fault and so on and they don't really tell you what is happening. ( I haven't flown any version of the ATR so I have no experience with this). He also mentioned that with the automatic rudder trim until you are very comfortable with it , that it can throw people off as to what is really happening.
Perhaps a little too much automation mixed with all the other difficulties. Just a thought.
He also mentioned that as part of the industry group that worked on the ATR 72-600 they recommended it be a different type rating since in their minds it was so different. The 5 DU's no standard instruments and so on. It of course is not a new type.
Hopefully some good factual evidence will come out and prevent this from happening again.

And then stalled / spun it. Even with both engines out for whatever reason it should not be too much to ask that a pilot not spin into the ground. If they had stayed wings level perhaps a few more people might have lived.
