There is a famous story about how an F16 got grounded because an half inch metal pin was missing from the cockpit canopy. Nobody knew what the pin did or if it was even necessary but you can't fly a plan that 'missing a part'. After several days of being grounded they finally reached out to a guy who had retired 20 years ago who told them the pin was a part of a analogue sensor that had been replaced nearly 30 years ago. Only the pin remained as a vestigial organ since it was part of the airframe design.

It doesn't matter how well you document things there will always be tribal / personal knowledge.

Even if stuff is written down you have to know where to look.

It’s a great story, but I assure you there is a pretty high percentage of airplanes flying with missing parts and systems placarded as INOP in both military and civilian aviation.

I babysat for a military fighter jet mechanic when I was young, he said when they dismantled and rebuilt planes there was a drawer for all the spare parts that were left over.

That's one of the things I love about AI: It's excellent at figuring out where to look, because it can digest so many documents so much faster than a person.
