Signed a logbook from 1976 and the piston wear numbers shocked me
That old engine logbook from a DC-3 I was inspecting had a compression reading of 72/80 from 1976, and I realized those numbers were better than half the engines I see roll through the hangar today, so is it really the parts that changed or just how we treat them?

A buddy of mine ran a crop duster for years and swore by the same thing. He'd pull an engine at TBO and the jugs would still look new while guys half his hours were already on their third top overhaul. His trick was simple stuff, letting the thing warm up before hammering it and not babying it either, just running it how it was meant to be run. Old school guys knew these motors wanted to work, and sitting around or getting short hops all day is what kills them. Treat a radial like a lawnmower and it'll act like one.
