Most props have a Time Between Overhaul (TBO) of 2000-2400 hours and 60-72 months, whichever comes first. You'd have to average more than 400 hours/year for the hours to come first. For most of us, the months come first. For a typical GA airplane that flies 100 hours a year, the prop may come due for overhaul in less than 500 hours. Do we have to overhaul our props that often?
