Fresh Out Of The Paint Shop
A few years ago, an engineer, friend and pilot shared a story about retrieving his Cessna 182RG from the paint shop. Before he took the plane out for a run-up and test flight, he asked his even more meticulous engineer-spouse do the preflight. When she did, she discovered something rather important. The bolts and nuts that connected the elevators were just hand-tightened, unsecured by cotter pins. The bolts and nuts securing the primary pitch control surfaces were essentially ready to fall out. Not good. My friend managed a major nuclear facility in Idaho, and he shared the story with his workforce as an example why operators should trust, but verify others work.
