What is the requirement from Manufacturers perspective, but also recommended for this prop V530TA-D35 on a YAK-52: 1. doing Aero's 2. normal flying I believe that the manufacturer recommended from the old Russian logbook 400 hours or 6 years, our local Russian AMO says 500 hours or 5 years. Our local Prop Centre says at least 3 years if you do Aero's due to torgue/forces on the prop. Our current prop is at +-220 hours Since overhauled, but last overhaul 2004. Total hours +-860 and manufactured 1988 However it was removed at 131 hours and 1 year from aircraft in 2005. It had 2 MPI inspections between 2005 and 2013 Was fitted to aircraft again in 2013 at 161 hours. So it "flew" approx 30 hours on another aircraft. It is currently in the Prop Centre as there was some wear and tear on the Furrells which need repair. (caused slight play on blades) This is in South Africa flying Non Type Certified or similar to Experimental in other countries. However, from safety aspect, what is the recommendation regarding overhaul timelines?
