    Had to repair the fabric in this area on my bird. When talking to my IA, he recommended using 3", 2", and 1" tapes to help stiffen the fabric in this area. One of the problems I was having was the screws where pulling through the fabric. Maybe this with other modifications might actually keep this area in tact.
    Here I've got 2" and 1". Didn't have any 3" available. Will use the 3" when I recover the wings in the unforseen future.

    Completed an annual on a Pacer yesterday where both left and right inspection plates at the flap bell cranks were shucking plates and breaking the plastic grommets. Made some of the aluminum angle plates like I pictured in the first post of this thread and really stiffened up that area. Should quit being an issue. Sorry I didn't take any pictures but it was 103 degrees and the owner and I got started at 7:15 and got him headed home at 6:30 after a complete annual inspection with some dependencies. I'll get some pictures next time he is here.

    Did you bond in new grommets in addition to the aluminum angle plates? were / are the inspection plates circular and clip in style?

    I have rectangular plates there that use screws into the grommets. Actually, I currently have a same size rectangular backing plate with nut plates, and the screws go through what is left of the grommet and into the backing plate.

    I have started the fab of the angle plates you show, guess I am wondering if i should rebond some grommets and then also incorporate the nutplates for the attach of the rectangular covers to the angle plate.
    Thoughts?

    The plastic grommet was in good enough shape that I could slip the inspection plate clip over it without any problem. Could just as well glue the fabric to the aluminum angle with Stewert's glue or contact cement to achieve the same thing I think.

    I use Steve's aluminium rectangular inspection rings. I glued them with Stewart's glue. Then I put a cover doiley over using thin fabric and Stewart's glue and thoroughly ironed them down. Then I cut the fabric inside the rectangle ring diagonally. I fold and glue the triangle flaps inside the wing, then ironed them down. This made a strong and very stiff inspection hole. If I were fixing an existing bad inspection ring. I would remove the old ring then trim out frayed fabric and glue a new fabric patch in place first. I've done this repair up through silver in a day and got the plane airworthy and on their way home.

    I've just been doing the wing root repair and needed a better way to spray vertically up. I modified my favourite spraygun with a 90 degree elbow, and it worked really well.image.jpg
