I haven’t yet had a chance to work on aerospace (or beyond) equipment though I do work on medical grade things and some of the parts are aerospace certified, though they haven’t been put through the ringer. In particular, I work with high voltage/amperage, high liquid pressure and high temperature systems. Some of it has been running for close to 25-30 years with very few issues. Only recently have I had to open a power supply that degraded since it was first put into service (over 20 years ago). I’ve gotten into a habit of identifying parts that, through experience, I know will fail or can fail and replaced them with ones that are all but guaranteed to outlive me. I want the person, if anyone, who comes after to see the work that’s of higher standard than what came out of the factory. No machine can continue working forever, but one can get much closer to having fewer failure points. As an aside, to get to here however was a struggle of obtaining all sorts of things I shouldn’t have access to because the manufacturer started locking access down heavily. Story for another time.
