Don't ask me how I know, but checking if a modern engine has been shock loaded involves a complete strip down. Neither the CAA or LAA will accept anything less if the engine has been brought to a stop by the prop making contact with the ground or other immovable object.
My guess for wartime would be a straight engine swap. But a splintering wooden prop will not always stop the engine.

Thanks, I was thinking that must be the case.

I've just finished reading the history of RAF Southend during WWII.
There are various references to aircraft suffering damage when their props hit the ground, and having to undergo
"shock load testing".
I wonder how they did it back then, would it have entailed a full engine strip down ? How else would you know if the
crankshaft was cracked for example ?
How do they do it now ? If an aircraft noses over on landing and the engine comes to a sudden stop, what is the
procedure ? Can you determine what damage may have been done without disassembling the engine ?
I know for instance that on outboard motors, there is a key designed to break if the prop hit something, to save
damaging the motor itself.
