Overheard a QA guy say my wiring looked 'amateur hour' and it made me think

Was standing near the break room at a regional airport last Friday and heard a quality auditor telling someone he'd flagged a harness I did on a King Air 200. He said the zip ties were too tight and could pinch the wire over time. Honestly, I always pulled them snug so nothing rattled, but now I'm second guessing every bundle I've done in the last year. Has anyone else had a QA call you out on something you thought was standard?

Man, that's rough. QA's job is to nitpick, but that comment was uncalled for. Tight zip ties are a real thing though. They can crush insulation over time, especially in a hot engine bay. Easiest fix is to just snip them flush, not crank them down. Don't let one guy rattle your confidence. You're probably fine, just take the feedback.

Wait, you're telling me there's actually a specific way to tighten zip ties on something like a King Air? I mean I get not wanting to crush stuff, but I always thought the whole point was to make it so tight nothing moves. @caseyw12 is right though, I've seen some cracked insulation from overtightened ties on older planes after years of vibration. It's crazy to think something as simple as a zip tie pull can cause problems down the road.
