Rear Seat Lap Belt Bracket Corrosion
I decided to remove my rear seat belts for thorough cleaning after an unfortunate barfing incident while giving a Young Eagles ride...
When I removed the lap belt from the side attach points I discovered surface rust on the brackets as depicted in the attached pictures. I removed the brackets and plan to take a wire wheel to them, then prime and paint them to prevent further rust. I have a few questions I wanted to run by the forum, as I am handy, but not a builder, nor A&P, and these are what I would deem safety-critical pieces of hardware.
1) Is removing the surface rust with a wire wheel, painting, re-installing, and putting back into service a perfectly safe and acceptable practice?
2) What would cause rust like this? There isn't a speck of rust anywhere else on the airplane. Could it be a case of incompatible metals?
3) Shouldn't this kind of thing be caught at every Condition Inspection? Maybe it was observed last time but I'm over reacting...?
I have Hooker Harnesses if it makes any difference.
Thanks for the insight!
