A torque wrench check at the Denver hangar showed me I was off by 15 foot-pounds

I was doing a routine wheel change on a King Air last week and my new partner asked to double-check my torque. I was sure I had it right, but his wrench clicked at 15 foot-pounds less than mine. Turns out my wrench hadn't been calibrated in over two years and was giving false readings. Has anyone else had a tool calibration issue sneak up on them like that?

Honestly, 15 foot-pounds on a wheel nut? That's not a huge margin. It's not like you left it finger-tight. Tools drift, it happens. As long as the wheel stayed on, I'd call it a learning moment, not a crisis.

Check your torque wrench every few months with a known weight. Mine was off by ten pounds last year and I had no idea. A quick calibration saved me from a real headache later on.
