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?

Shoutout to the cheap goat skin I found at a market in Austin

I grabbed a piece for a small journal cover, thinking it would be a bit stiff but fine. After paring it down to about 0.8mm, it turned out way more stretchy than any calf I've used. The spine warped a little during drying because I didn't account for that give. Learned that goat skin needs a different backing board pressure, maybe even a lighter glue. Anyone else run into this with thinner goat leather?
