My neighbor is retired from Boeing. Started on factory floor, fresh out of the Navy. Was a troubleshooter/inspector for years. He stays on top of all the Boeing news. He has A LOT to say about MD's execs destroying Boeing's obsessive culture of engineering and quality. As of two days ago, his current understanding is the plugs are removed and reinstalled when the interiors are installed. Meaning it could have been mfg correctly (in Wichita, KS) and then reinstalled incorrectly (Renton, WA?). He isn't yet clear about who was responsible for what. Like how this could have been missed by the multiple inspections. Heresay, so take it or leave it. Just repeating what he tells me. I've encouraged him to comment, but he's not that kind of person.
