It is infact #1 eng uptrim, #2 engine autofeather, #2 engine roll back. #2 engine didn't flameout, it remained running until the end....
Both engines responded exactly as designed to the commands they were given.
Uptrim/Autofeather was commanded when there was nothing wrong...
Clarification, please, for a non-multi pilot.
Aerplane climbing normally, then; Uptrim (of #1) and autofeather (of #2) was commanded when there was nothing wrong with #2. Was that a pilot-initiated command or a spurious fault? Or don't we know? In other words, what event kicked off the autofeather of one good engine (#2) and the pilot's shutting down the other good engine (#1)?
Wasn't #2 power lever firewalled at one stage during the decent? If #2 was running, why didn't it unfeather, wind up, and save the day? Was it just that it was firewalled too late to do that?
