My Super Cub has well over 12,000 hours and the door pins and the sockets that the door pins fit into are worn and let the door rattle. It doesn't take 12K hours to do this. I started welding bushings in the recepticles to make a tight fit and to keep from wearing a notch in the pins.
Front receptical.
Rear receptical.
Note the hole drilled in the "U" channel that makes up the seal for the flip up window and has 3 #4 PK screws screwed into it to retain the rear "D" window. There is no where for water to escape this channel that is welded over a round tube. I have found lots of these rusted completely through. This is a 1500 hr airframe with an aluminized coating from the factory that we found no corrosion on so instead of cutting the channel off like I normally do I used a Blair hole cutter and drilled a hole in the channel to inspect the tube underneath.
