Found a stat about wire corrosion rates that surprised me
I was digging through some old FAA advisory circulars last weekend and found one that said 30% of all avionics failures trace back to corrosion in connectors or splices. That number is way higher than I expected, especially because most of the time we blame the box itself. The report specifically pointed out moisture getting trapped in unsealed D-sub pins as a major culprit. Made me rethink how I prep my crimps and whether I should start heatshrinking every single pin. Anyone else come across that stat or have a go-to sealant for backshells?

That 30% number makes me wonder how many times I've blamed a bad crimp on the wire when it was really me...

Gasped when I read that stat too, @adam_nguyen7. Never thought moisture in D-subs could be that sneaky.

And you know @barbara84, that stat is exactly why I stopped blaming my tools every time something goes wrong. Now I just blame the humidity like it's an old enemy. At this rate I'll need a dehumidifier just for my workbench.
