  1. 17:33 "sealed bearing was incorrectly assembled ... unsealed side more suspectible to moisture" Am I the only one reading this as "bearing was actually installed backwards"? Where's the QA process that's designed to catch exactly this kind of problems? Surely there must be a process where every step is verified by at least one another human being or the aircraft parts wouldn't be that expensive?
