Prop overhaul - how frequently?
In a normally aspirated 337G, how long should one go between prop overhauls? I know the SB says to service at 500 hrs, but for Part 91 operations, in real life is there a fixed time or is it "on condition"? In short, if blades have been inspected and are within spec and properly balanced, if there are no cracks visible when you remove the spinners, and if there are no leaks and the units are operating fine, do you keep flying even if it's been 1000 - 2000 hrs since last OH? What's your field experience on how long do they normally go between overhauls?
