Serious question, has anyone else had a torque wrench calibration slip by a hair?

I was torquing a set of cylinder base nuts on a Lycoming O-360 last week and my click felt a bit soft. Checked the calibration cert, and it was just outside the 4% spec from six months ago. It made me double-check every single tool date now. How often do you guys actually send yours out versus just trusting the sticker?

Used to just go by the sticker date. That soft click on a prop bolt last year was a real wake up call. Now I send them out like clockwork, no questions asked.

Trusted my old beam-style for years because it was simple. Then I caught myself squinting at the scale in bad hangar light, realizing I was probably adding a ten-pound "eyeball adjustment" to every reading. That was the end of my career as a human calibration stand. You ever have a moment where you just stop trusting your own eyes?

Your story about the hangar light is a perfect example of why I started using a digital torque adapter. It takes my old click wrench and removes the guesswork, showing the exact number on a screen. Skyler800, that kind of tool might save you from squinting too.
