TIL about hidden wire chafing on a King Air 200 last month

I was doing a routine inspection on a King Air 200 in Wichita and found a bundle of wires chafed nearly through behind the avionics bay panel. A small zip tie had shifted over time and was rubbing against the harness, could have caused a short in flight. Has anyone else caught weird wear like that on older airframes?

Caught a 1980s Learjet with a screw poking through the insulation on a bundle near the tail. Was just sitting there for years waiting to ground the whole electrical system.

@the_brian found the factory souvenir. Bet that screw had seniority over the whole crew.

Had one of those on a Gulfstream once. Best thing to do is grab a borescope and a good inspection mirror and trace every wire near any fastener or bracket. Takes forever but you'll find all the hidden gifts the factory left behind. Throw some spiral wrap or split loom over any spot that looks even slightly sketchy.
