How a hangar chat shifted my take on following the book

I always figured that after years on the job, a good mechanic could rely on feel and skip some tiny steps in the manual. My mind changed after a talk with a veteran at the local airfield. He told me about a simple annual inspection on a Piper where he rushed and didn't properly torque one single nut on a landing gear bracket. A week later, the pilot reported a weird shimmy on landing, and they found the nut had backed off almost completely. That one small skip meant a full gear check and a very unhappy owner. It hit me that every line in that manual is there because someone, somewhere, learned the hard way. Now I respect the process down to the last detail. It's like in my dental work, where skipping a step might mean a cavity comes back, but in planes, the stakes are so much higher.

That was just one nut on a Piper... it's crazy how something that small could've taken out the landing gear.

One missed step, potential disaster.

When you say 'one missed step', it's wild how small oversights add up. Like @sarahkim said about that one nut on a Piper, a single loose bolt can wreck a whole system. I remember reading about a missing cotter pin that made a plane's flap jam. How often do mechanics actually spot these things before they become a problem? Is there a good system to catch them, or does it come down to luck?
