BEagle,
Much as I dislike the idea, I regret that I must disagree with you.
IF everything had happened in exactly the same way and the helicopter had forced landed without any casualties then; given the discrepancies in procedures, compliance with ASI's, basic Airmanship such as altimeter settings; the usage of nav aids and the total disregard of crew duty limitations; crew meal requirements, outbriefing etc - then what would have been the finding of the BOI?
I would respectfully suggest that it would have been "Negligence"
and that if the BOI had not so found; then the AOC would have!!
