There is no such requirement. Even if there were such a requirement there
is no guarantee the engine teardown would be done. Just because there is no
prop strike in the log book does not mean it did not happen.

There is no regulatory requirement, but both Lycoming and Continental "require"
a tear down inspection after any sort of prop strike. For us small operators, it's
just a very strong suggestion from the manufacturer. After my engine failure which
had a very small scuffing of the prop blades, the insurance company didn't even bat
an eye on paying for the teardown. Ran about $3K if I recall.
