I finally stopped trusting the tester on the ramp and started checking pins by hand
Two guys on my crew swear the $900 bond tester is gospel and skip the wiggle check, but I found a broken pin on a CRJ 200 last month that it passed clean. So is the tester worth the money or is hand checking pins still the real standard in 2024?

Watched a guy spend 20 minutes chasing a fuel leak on a 737 last year, swapping O-rings and tightening fittings, all because the bond tester said the connector was fine. Turns out one pin had walked back into the shell just enough to lose contact under vibration but still passed the static test every time. He finally pulled the connector apart, wiggled it, and the pin fell out in his hand. Cost us a whole shift over a check that takes ten seconds. I get why guys trust the box, it gives you a warm fuzzy and a printout, but the printout don't show you a pin that's loose in its hole. Hand check first, tester as backup, that's the order that keeps you out of the hangar at 2am.
