The other day I was landing and pulled the carb heat, which pulled about 6 inches out of the panel. I landed, and thinking the cable had broken, removed the cowl to take a look. I didn't take any pictures, but the bolt attaching the cable to the arm that controls the carb heat flapper had worn all the way through the arm and pulled out. On closer inspection, the bolt had also been worn so only about 30% of the bolt cross section was remaining. I replaced the flapper arm so I could keep flying, but am looking at the design and trying to come up with a fix. I think I will weld on a thicker and wider arm so I can drill a larger hole and insert a bearing around the bolt which should make it hold up a bit better. The cabin heat uses a similar design and control cable, but there is no wear at that connection.

No, even with the engine idling they would at the least be damaged and likely torn off. They are sturdy when closed, and big enough to make getting everything and everybody in when opened, but are just not designed to be open and flapping in the breeze.
