Bristow / Era Aw139 Accident   

After the fact it's always easy to armchair quarterback and that is not intended to be what this is, but I'm curious to know why the overhead ECL's weren't used instead of using the engine levers.  Sometimes you just have to pull some pilot skills out of your rear and make things happen.  It looks like that's what they did but it would still be nice to know.

With both EECs overspeeding it sounds like a link was lost and each engine thought the other sustained an engine failure and they both just dumped fuel to the fire to maintain either the others missing power or a computer perceived loss of RPM.

I know first hand from flying these machines that when doing the daily ground based powerchecks Era wanted done, that if they were performed incorrectly and you took one engine from flight to idle, and moved the other from idle to flight anywhere in the rpm transition stage, rather than moving the #2 to flight before bringing the other to idle, or let it stabilize at idle and then bring the #2 to flight... the online engine computer would think that the other went offline and dump full throttle to the engine as if it was a sustained inflight power loss.  So much torque was added that it would overspeed the RPM on the ground and rotate a gross weight machine 10-20 degrees left skidding the nose across dry pavement.
