In Europe there are mandatory airframe limits after which an airplane can not be flown. The limits are on the order of 8000 ~ 10000 hours. With average use (about 200 hrs /year) This translates into 40 years of useful life. The important thing to remember is that stress on the airframe is cumulative. If you are buying a old used plane then have a mechanic look over the entire plane not just the engine for sign of stress. reha orion!reha
