I am a bit confused about the connection of the F-915 outer seat rib, which attaches to the F-904 and F-705 bulkheads.
The instructions say ?position the top of the rib flange so the distance between the outside of the web and the outer edge of the seat skin is 0.032?. This means a thin strip of flange will be visible past the edge of the seat skin when viewed from the top.?
My confusion stems from the following. At the aft end of the rib, with the rib clecoed (and bolted) to the F-705, and with the seat skin clecoed in place, the skin overhangs that aft part by a good 0.040?. Now, I know that the rib is to be formed to make the curve as it mates to the F-904, but here at the aft end, you can?t bend the rib sideways, so you can?t get the skin to recess inwards by the required 0.032?. Further forward you can, but not at the aft part.
I would think that maybe you could simply trim the skin back, but since the rib is curved, where do you stop trimming as you proceed forward?
I don?t know if I have described things well, but any insights would be appreciated
