I still remember the Westland Split pin holes, that must have been drilled from both sides or offset as they would line up one side, but not the other.
Almost as bad as Boeing not drilling the holes in the first place. The key question, however, is were MoD content with your example? They were on Chinook.
Then it happened again.......

French helicopters were problematic for me.
I remain convinced that is where the RAF Chief Engineer got his idea from to stop maintaining configuration control.
I recall, 40 years ago, an Admiral being impressed with my French as I was apparently repairing a Gazelle clutch with my sole reference being a French drawing. We kept the translation in a drawer. At least we had an audit trail to our standard of clutch, unlike the Argie Chinook pubs used by the RAF.
Excellent summary of Imperial threads. My memory tells me there is a Def Stan on your labels, especially a warning of Unified threads. I'd still want to know if the nut in this case had been re-used, as that is a common reason for over-tightening. If such questions had been asked I'm sure the local journalist would have twigged its importance. What we're reading at the moment is a series of unchallenged and increasingly ludicrous MoD statements.
