Try this one for size the details have been changed slightly to protect the innocent.
Pilot comes "in sorry boys but I've overtorqued the aircraft, my fault incorrect engine handling".
Engineers start to replace some very expensive hardware.
Part M gets involved and produces a process for returning the aircraft to service.
Part of this process is a check of the engine management system.
Engineers work through the process to humour the Part M, they know the cause of the problem ( he is sitting in the crewroom).
Bottom line is if no faults found replace the Fuel Control Unit, mega expensive. A test bed run will cost a few thousand with the recertification.
Engineers refuse to change the unit as they know that the cause was the "stick to seat interface".
The Part M insisted the unit was changed. Th engineers were forced to change it under protest.
Can't you just wait till that happens to you!!!!!!!!!!!!!!!!!!!!!!1
