I wasn't sure about the nylon brackets when I installed them but went ahead because they looked so good. I should have listened to my gut. I had the pilot side break in half right where the AN screw goes through it. I'm glad I was not loading my daughter when it broke, that door came down like a hammer. I replaced it with the metal stock bracket and will replace the other one soon so I don't get a repeat failure. I was surprised they failed so quick I have less than 200 hours on the plane and the doors have always been babied.
