I'm speechless
They use SAE nuts and bolts. "Society of Automotive Engineers and refers to the system of inch-based fasteners used primarily in North America"
Is that the standard in the airline industry? For example, does Embraer use SAE too? Lockheed (I thought the US military used metric)?
Dunno. My info's from https://www.reddit.com/r/aviationmaintenance/comments/botlch...
Update - google says Embraer uses SAE. Apparently Airbus helicopters are metric though.
Airbus uses US measurements - i.e., not the metric system?
