Pulled a corroded connector from a 727 last month in Salt Lake City
We were tracing a intermittent comm issue on an old 727 that's been sitting in the desert. I opened a panel near the wing root and found a connector filled with green crust. Took me three hours to clean it up with contact cleaner and a tiny wire brush. The radio worked perfect after that. Anyone run into corrosion this bad on older airframes?

Nah, that's pretty standard for desert storage actually. The green crust is usually from salt spray or just years of thermal cycling drawing moisture in. But just a heads up, on the 727 you gotta be careful with that wing root panel - there's a bonding strap in there that can get brittle and break if you flex it too much. Seen guys snap those and then have to chase a whole different set of grounding issues.
