Recommended overhauls on constant-speed propellers are important. Here is a blade root that would not pass inspection due to scraping—most likely caused by improper lubrication or periods of inactivity.

In Case You Missed It
Flight Testing
Even current pilots need to hone specific skills before attempting a first flight in their homebuilts. There's only one way to do that: practice. And then practice some more.
If it’s on an amateur-built experimental (this is still Kitplanes, right?), by the FAA’s definition it’s not airworthy from the get-go.
Whether it’s in a condition for safe operation is a different matter altogether,
Ironically, we do give them an airworthiness certificate.
