Prop replacement and Engine teardown inspection right there. About 2 years ago I did an engine change on a 172 and it flew for about 100 hours and had a propstrike. Replaced prop and installed new engine and aircraft flew for about another 200 hours and had another propstrike only this time it was bad enough where it did firewall damage and had to replace some belly skin right behind the firewall. You really have to plant an airplane really hard to do that. Some flight school planes take alot of abuse.
