We don't do the check to the ground because it's a 6 million dollar corporate aircraft.
Quite.
We did all these tricks in the 206 but not in twins because they were deemed "too costly" to risk bending, plus the assumption that a simultaneous total power failure in a twin just wouldn't happen.
I don't recall ever doing total power failure in the high hover in a twin, but maybe senility has intervened. It was trick enough in a 206 even when expecting it. In a 355 (my ship) - for real? - I wouldn't want to have been there.
It ay be that this event has highlighted a chink in our armour. I daresay this accident will lead to one certain result - mandatory CVRs and/or data recorders. I hope it doesn't get as far as mandatory two pilots but I'm not holding my breath.
