We all know sails have various life spans, anyone have thoughts on the lifespan of an air frame, assume in good condition, no accidents or major whacking. Are we talking 10-15 yrs, 15-20 or something else? Understanding the bones are only useful if they can be fashioned with skin. Thanks and happy flights!
There are too many variables to give any good answer. A glider that I often flew in big air developed tiny cracks, radiating from bolt-holes in the crossbars. A glider that I had stored in a garage developed corrosion inside the tubing (it was not my glider, and I do not believe that the owner ever paste-waxed the hardware or the tubing, inside or outside).
Neither glider could be trusted in serious air, now. Corrosion can be prevented, but not repaired, beyond a certain point. The airframe with cracks coming from the bolt-holes could be repaired with modern fittings, but that old design is not worthwhile now. If you take good care of a glider, the airframe can usually outlast the sail, and maybe a second sail. Noisy landings can shorten the life of an airframe by a lot. If you take a glider to the beach, or travel in bad weather without the glider being in a waterproof bag, corrosion may bite you.
Pssst! New pilot? Free advice, maybe worth the price,
