An overstress is when a pilot pull’s more “g” than the aircraft is rated for. While it’s true that there is an engineering pad attached to the g-limit, the pad is inelastic – in other words, each overstress event will to a greater or lesser degree reduce long-term airframe integrity and service life.
Overstressing a jet is considered bad form, but it’s also something that will happen from time to time. I wouldn’t trust a fighter pilot who’d never overstressed his aircraft. It either meant he didn’t trust himself, or that he wasn’t trying hard enough to fly up against the performance limits, the “edge of the envelope.” But it’s also true that you just wouldn’t want to try to make a career out of overstressing aircraft.
