Don't they have many ways to prevent bolts from unscrewing? I know at least a few by doing mechanical stuff on motorcycles, and it seems that other planes don't have such problems (at least not within 2 months after the last inspection).
- aredox 3y agoThere are washers, or thread lock glue, but it is still a question of correct execution: has the glue been applied? Was the glue batch used before its shelf life? Were the parts degreased before glue application? Or did anyone decided to cut corners by using an old batch/skipping degreasing/not putting glue because they were late on delivery?
- MarkMarine 3y agosafety wire and cotter pins are preferred methods on aircraft.
- lobsterthief 3y agoYes. For mission-critical bolts and nuts, absolutely safety wire and cotter pins should be used.
- MarkMarine 3y agoThe engineers at Bell also thought that blind bolts you couldn’t inspect in dailies should be wired.
