Keyrekt. There was a study at IA state aero engineering I think, of the finite element analysis on a 54 Bonanza(post design, obviously), and I'm going from memory but they figured under normal GA use, it would take >55,000 hours before there were structural concerns. Of course, different flight loads mean different measures but even at half of the finite analysis point, most airframes don't even come close.
