how much over torque a rotor strike actually is on the MGB?
isn't the inertial shock all from the blades own inertia?
with modern testing method can't we revalidate a part fully?
Firstly G-TIMO appears to have suffered a sudden stoppage not a blade strike, there is a difference.
Dont forget the engine is still driving as well unless it had been shut down or failed.
We had a 365 that had a tail strike which lead to the fenestron cutting a slot in the duct.
The main gearbox was found to have a hard spot in rotation and was replaced with the other tail drive components..
What was missed was that the engine manufacturer required the engines to be inspected.
Shortly after return to service the aircraft suffered an engine failure.
This incident would have been classed as a strike not a stoppage.
