The torque wrench that lied to me for 6 months

I was torquing down some landing gear bolts on a Cessna 172 at our hangar in Tucson and felt something off. Ran the wrench against our calibrated test rig and it was reading 20% low the whole time. Turns out I never stored it in its case and the mechanism drifted pretty bad. Anybody else skip the annual torque wrench check and get bit later?

Tbh that's on you for not checking it sooner.

Haha yeah I guess you're right @dixon.amy, I should've checked it sooner but I'm just a slow learner I guess.

20% low" sounds rough but landing gear is usually way overdesigned for that.
