Brief Description: Center Section: Right Outboard Seat Rib
I drew center lines along the flanges of the right outboard seat rib and then marked where the rivet holes would be since this rib is not pre-punched. I then fluted the rib in between the rivet marks in order to shape it according to the curved shape of the pre-punched holes in the top and bottom skins. This rib was then match drilled to the skins and the bulkheads.
