Pro tip: Check your crimp tool calibration before a big job
Last month I was working on a 737-800 at McCarran and kept getting intermittent readings on a pitot-static test. Spent like 3 hours chasing the problem until a senior guy looked at my crimps and said they looked loose. Took my tool to the cal lab and it was off by 0.3mm, which is just enough to cause bad connections. Anyone else ever had a crimper drift out of spec without realizing it?

My buddy down in ATL had the exact same thing happen on a CRJ-200, got called out by a QC inspector on a loose cannon plug and his crimper was off by almost half a millimeter. He swore he checked it six months prior and it was fine, so now he has it tested every month like clockwork. That little bit of drift can cause intermittent problems that drive you crazy for days.

Meanwhile back in 2019 my torque wrench was reading 20% low for three months before I caught it.

My buddy Marcus over at Delta had his Snap-on crimper drift on him twice before he caught it. First time it was a loose ground wire on an MD-80 that kept failing continuity, took him four days to track down the problem. Now he marks his tooling with a date sticker and gets it checked every 90 days no matter what.
