Showerthought: I looked up the actual failure rate for a common connector and the numbers were not what I expected
I was reading an old FAA report from 2018 about in-flight faults. It said that for a specific, widely used D-sub connector in a certain avionics bay location, the primary cause of failure wasn't corrosion or vibration, but bent pins from repeated ground handling. The report claimed bent pins caused over 60% of the faults for that part. I always thought environmental factors were the big issue. Has anyone else seen data that changed how you approach a routine check?
