Rant: Lost 6 hours on a fuel leak at BNA because the jack pad was 1/4 inch off
Spent a whole Tuesday chasing a seep on a 737 that turned out to be a gouged O-ring from a loaner jack that wasn't seated right. Anybody got a go-to trick for catching that before you waste a shift?

That "loaner jack that wasn't seated right" line hit me in the gut because I've been there twice this year. We had a 737 with a mystery seep at the wing root and after pulling panels and pressure testing for most of a shift, the whole thing came back to a borrowed jack with a chewed up pad that nicked the O-ring on the way up. Now the rule on my crew is simple: any jack that ain't ours gets wiped down and eyeballed before it goes under a plane, no exceptions. I also mark the pad contact points with a paint pen so I can see right away if the thing is sitting crooked or walked off center. Takes two minutes and it has saved me more than one long night. Six hours on a Tuesday stings but at least you know you ain't the only one who has paid that tax.
