Learned a hard lesson about torque values on Gulfstream gear doors last month

I was working a 12-year-old G450 at a shop in Savannah and had a gear door that kept binding after a retraction test. Turns out the torque values in the old manual were for the wrong bolt grade, and I'd been overtightening them for years. Anybody else found outdated specs in older aircraft manuals that caused you headaches?

Man, a whole decade following the wrong torque values because the manual was wrong? That's terrifying. The fact that a 12-year-old jet still had bad specs floating around in the documentation is a massive oversight. Makes you wonder how many other little errors are hiding in those old binders.

Found a wrong bolt callout in a 1990s Lear 35 manual last spring. Nightmare.

Errors hide everywhere, manuals are just the start.
