PSA: I came around on doing walk-arounds after every job
I always thought a quick visual check was enough after finishing up, especially on routine stuff. That changed when I was wrapping up a brake line swap and almost missed a loose access panel on the opposite side. It was just hanging there, and if it had come off in flight, well, that wouldn't have been good. Now I do a proper slow walk around the whole aircraft, no exceptions. It takes an extra minute or two, but I've found things like a worn static wick and a chafed wire bundle since I started. It's not glamorous, but it beats the alternative. My old boss used to call it pointless busywork, but he's not the one who would have to fill out the paperwork. Guess I'm a convert now.
