I 'd like to know if anyone has ever had a "prop strike" for an engine that was not running, just parked and if you disassembled the engine as Cont advises, did you find any internal damage? Thanks of any help.

I have a J3 Cub with a C90 that was tied down, with FBO supplied ropes that were worn out, and yes I should have spent $20 at the hardware store for chains that would have held. I wasn't expecting 50 mph wind in the middle of winter.
The plane hit hard enough to crack the wood prop.
Cont Service Bulletin says a static impact is really the same as when running, doesn't sound logical, but there it is and advises full disassembly and check internal parts. I would have thought a checkout of runout of the prop flange with a dial micrometer would be the first step, but Cont doesn't even mention that.
A Cub is to airplanes as a golden retriever is to dogs.
