SASless #1312.
I wondered about the effect of freewheel problems. A couple of points; many years ago I had a freewheel unit drive itself into re-engagement in a Hiller when established in an auto about 500', just after I had closed the throttle fully for an EOL exercise, .... the RRPM were "snatched" down dramatically to about 70% of their normal auto RPM and we "fell like a stone". Onlookers asked later why I didn't hear the backfiring going on behind me, perhaps I was too busy trying to wind the RPM back on with the ground rapidly approaching, but anyway a Doc later told me that hearing is the first sense to shut down in stressful situations. Also, like you, I remember the rotors turning very slowly after I completed the "EOL", but then that was because the rotors were trying to turn over a stopped piston engine (I even closed the ICO in the flare!). That can't happen with a turbine can it? I have every faith that the AAIB will come up with a full and detailed report in due course.
