Try being in a life threatening situation dealing with a system that does not respond to your training, or the sage advice just provided by the OEM which just happens to be missing a couple of salient points.
Good point.
Many years ago I had a main rotor blade delamination in a Bell 212 (twin Huey).
The aircraft rolled upside down, wouldn't respond to the controls properly and was bangin' like h$ll.
I had NO CLUE what was wrong - but I knew it was bad.
Irish luck got the rocket back on the ground and it was determined that the inflight damage was so severe the aircraft was totalled.
Never wanna do anything like that again. 😳
