Hi Gents,

I am working on the wings of an M-5-235C and I found that the skin with the reinforcement bended out around inboard flap hinge bracket cut. I dont know the history of the aircraft and I was wondering if it was made by the factory or something happened with the wings before. It is the same on both wings so I guess it was designed like that but to make sure I'd rather ask maybe M-5 owners can check... Please see pics attached. Thanks a lot.

That’s the hole for the flap pushrod from the factory.

That bend is not suppose to be there. This happens on the M4 or M5 wing without gust locks with a wind from the back. The flap is held up by spring tension. A gust from the back can over come the spring and slam the flap down. That bend out is made from the push-rod hitting the side of the opening when the wind pushes the flap all the way down which is beyond the normal limits of travel.

Does not sound good. Interesting that there is no visible damage on the pushrods. If this happens the pushrods would be damaged as well I guess.

It is very common thing to see that on the M5 wing. The aluminum skin is a lot softer than the steel push-rod. I made a set of external gust locks to put on my plane when I left it outside in the weather.

A lot of M4’s have this problem. Nothing is “damaged” because of it. I still don’t have fist locks on and mine get bent back often. Stupidly I keep pushing the skin back straight only for it to bend again next time I’m tail to the wind.
