Serious question, how do you trace an intermittent short when it only shows up on the ground?
Had a nav light circuit that tested clean in the hangar at Addison but popped the breaker every time the gear came up in flight. I finally zip tied a $15 dash cam in the wheel well and caught a chafed wire bundle brushing the strut on retraction. What's your go to trick for catching stuff that only fails under G load?
