Thought I was a pro at torque specs, then a 767 taught me otherwise
Spent 8 years torquing landing gear bolts to the book value every time. Last month in Dallas, a senior inspector pulled me aside after I did a nose strut. He showed me how the manual calls for a 10 percent reduction when the bolt has 3 threads exposed past the nut. Dumbest thing is the spec was right there in section 32-41, I just never flipped past the torque chart. Anyone else have a moment where the factory manual overruled what your old mentor drilled into you?
Reminds me of when I was learning to weld and my old boss swore up and down that you always tack both ends first to stop warping. Did it that way for years until a pipe fitter showed me a job where that actually made things worse because of how the part was clamped. Turns out the procedure sheet had a whole different order depending on the joint type and nobody ever told me. My boss wasn't wrong, he just learned one way and never ran into the case that broke it. Same deal with your manual, the chart is the easy answer but the notes under it are where the real info hides. Stuff like that makes you wonder how many other pages we all skip past because we think we already know the job.
