This accident is one of the classics which seems to get studied in most CRM courses. Crews are now trained to review their actions to ensure that they are appropriate. One of the areas about the conduct of the crew on this flight was that they did not properly review their actions. What is a little unfortunate about this is that the one time the Captain actually tried to review the state of play, he was interupted by yet another ATC transmission! I don't want to get into the 'pilot knocking ATC' mentality but you would have thought that it was fairly obvious, after the second offering of a tighter turn was rejected, that the captain didn't want one. Really, in the event of an engine failure, there is no great rush to get the aircraft on the ground (by that I mean a few minutes doesn't matter, I'm not suggesting continuing on to the destination!). Its more critical to get the aircraft sorted out, that any appropriate drills are complete, actions reviewed, and finally that the aircraft is stabilised early on the approach. You don't want to do a single engined go around with a heavy aircraft, even if Perf 'A' say's its O.K! Personally, I'm quite happy with a late / tight turn on when the aeroplane is working, but I when do a pre-departure emergency brief I always include a statement like "If we do have an emergency we'll come back in here and we'll ask for an 8 mile final". >The other fact is that only a month before I had flown on the flight deck >with that same captain as part of a familiarization programme.

The real shame about this accident is that if the engine had just held together a few seconds more they might have just cleared the M1 cutting, or if it had come apart a few seconds earlier they might have had long enough to successfully relight the good engine. Also, an awareness that disconnecting the Autothrottle would affect fuel flow to *both* engines might have helped the crew avoid misdiagnosing the failure. Personally, I think there is a case for better technical training for professional pilots, perhaps concentrating a bit more on general engineering principals & control systems.
