Just asking because I have never seen corrosion on those things - even when I lived in a salt air environment - but I have seen lots of grime....

I thought that was the case at first but the picture is AFTER I took it to a wire brush then to a wire wheel on the bench grinder. Its definitely corrosion. Anyway at only $16 a piece its worth replacing all of them on a flight control.

Interesting though is the lower rudder fairing didn't have a drain hole in it per plans and water had collected in it. I wonder if the lower bearing being in close proximity to it had anything to do with the corrosion being worse.

BTW...fully enjoyed your webinar a couple weeks ago!
