Ah yes Hammer Headed, don't forget you are talking about Bell where evolution not revolution is the way of life! I'm told that the handle on the tail boom baggage door on the 412 is the same as the handle originally use on the Bell 47!
Anyway, back to the discussion. My point is that whilst testing/checking a system is fine, in the case of the Hyd system interlock failing at 100% NR, what is the outcome? Nobody seems to have a definitive answer and I am still not convinced that the cab will still sit on the ground and not thrash itself to death. If this is the case does it not question the validity of the check in the first place?
