The pilot who questioned my solder joint taught me more than my A&P course
Back in 2019 I was working a line maintenance gig at KSDL, doing a pitot static swap on a Piper Archer. This old crop duster pilot who hung around the hangar wandered over and watched me tin a wire for about 30 seconds. He pointed at my joint and said, 'that's a cold one, you rushed the heat.' I got defensive, said I've done a hundred of these. He just shrugged and said 'then you've done a hundred wrong.' I re-did it with a slower iron and watched the solder flow proper, and sure enough the first one had that dull finish. That moment stuck because he wasn't a tech or an inspector, just a guy who'd seen enough bad splices over 40 years of flying. Ever have a non-avionics person spot something you missed on a harness that made you rethink your whole process?
Funny how the guy who flies the thing for a living spots the bad joint faster than the guy with the license on the wall. My soldering confidence is now officially lower than my golf score. Guess 40 years of trusting your life to other people's work gives you an eye for the sloppy stuff.
