Changed my mind on torque seal after 22 years, a leak at BNA finally did it
For most of my career I thought torque seal was mostly a feel good step, just something to slow down the next guy. Three weeks ago I was doing a walk around in Nashville and found a fuel line fitting on a King Air that was wet with a bead of seal still sitting there untouched. The seal had stayed put while the B nut backed off maybe a quarter turn over 200 hours, so the paint lied to everybody who looked at it. Now I mark across the flats and the nut body with a stripe instead of a single dab, and I log the torque value on the work order. What is your method for catching a loose fitting when the seal still looks clean?

Did you ever read that FAA advisory about mark alignment drifting over time?
