I started with the right hand flap this morning. I clecoed the skin and ribs together and placed the whole assembly into my āVā block fixture. I used my tungsten bucking bar to set the span wise rivets that join the top and bottom skins. Then I riveted the ribs to the skin. I had to use a blind rivet on the inboard rib adjacent to the nutplate as there was no room for a bucking bar. I set all the rivets except the bottom span wise ones that will attach the hinge to the flap. I will do those tomorrow.
