I am getting my airplane ready for sale. While discussing with mechanic he suggested that propeller OH might help with sale. Its 3 blade Hartzell installed new on 10/2000 .Since then TT on propellers is 2080 hours. According to Hartzell owners manual OH limits are 2400 hrs or 72 months. Of course its impossible to meet calendar requirements for the most private owners. When I OHed the engine in 2008 we decided not to OH propellers due to good condition. Propellers seems to be in good shape no leaks, very rarely needed to file them.I always get compliments from other plane owners who fly with me about how smooth the propellers sound. The plane flies regularly and rarely sat more than 1 week without flying. Question is should I OH propellers and price the airplane accordingly or let the potential new owner decide on his own and give him price break?
