    Default Left Wing Trailing edge 2nd bay by Flap Sheet Metal Break

    I noticed while detailing my Cub today that the Left wing trailing edge by the flap 2nd bay from the fuselage was sagging. It appears that the sheet metal that folds over in the region has broken possibly due to prop blast. Has anyone else had this problem? Anyone know of a fix?
    Here are three pictures. Looking aft at the left wing. Close up of what appears to be the break area by the rib and the right wing:

    All I have to offer is what our shop has done to repair this in the past. That's to put in a doubler. Our engineering department is working on a procedure for repair right now which should detail material type and such. Basically, repair in accordance with AC43.13.

    Thanks Clay.

    I have heard that both the airplanes in Australia have had this problem as well as the horizontal tail brace break. A couple of others have told me their stories as well.

    I've just found this same problem on #197 in New Zealand in exactly the same place. I'll try to get some decent photos

    Have you contacted CubCrafters Customer service? (Jeff Glab) I think that there is documentation on how to repair this if I remember correctly.

    Hi Pete, I have a customer asking if we know why this happened? Was it over speed extention? And if a fix has been brought into the production line? Thanks, Royce
