Showerthought: I used to scoff at torque wrench calibration, until it saved a landing gear job

I mean, I always thought calibrating torque wrenches was overkill, just paperwork. But last week, on a landing gear overhaul, my wrench was off by a few foot-pounds. If we hadn't caught it, the bolts might have been under-torqued. Maybe it's just me, but now I check calibration before every critical task. It's a small step that avoids big problems, idk.

Consider how many failures start as tiny, undetected errors. That calibration isn't just about a number, it's about the entire system's integrity. Makes it a non-negotiable step, not an optional one.

Non-negotiable step, @patricia732? I wish I'd known that before my 'tiny error' caused a monumental mess...

Heard about a buddy of mine who shrugged off calibration until his engine mount bolts started singing a stress chorus mid-flight. Kinda echoes what @patricia732 said about tiny errors snowballing into system failures. Turns out his wrench was so far out it was basically guessing, and he only found out during a routine audit that probably saved his bacon. The shop foreman made him recalibrate every tool in his box, which was a brutal but necessary lesson. Now he treats calibration like his morning coffee, absolutely essential before touching anything critical.
