While my -4 is in the paint shop, I planned to have the hub resealed. I got a call today from the A&P saying the prop shop won't reseal the hub as the prop is overdue for an overhaul. The recommended overhaul interval is 6 years.
The Hartzell CS prop is almost 14 years old and has about 800 hours on it. I installed it factory new in 2009. The plane is always hangered and the prop seems to work fine and look fine.
I'm struggling with decision of overhauling a (perfectly good?) prop just because it reached an arbitrary date (think Mike Busch Condition Based Maintenance philosophy) or flying with it until it starts to leak grease or exhibits some other undesirable behavior. What have others done when faced with this decision?
