Started working on the manual aileron trim kit. Drilled out the two platenuts indicated on the OP-20 Seat Rib Drilling Detail. Match drilled the two screw holes on the F-6124 Trim Bracket using the holes in the F-939 Right Forward Seat Floor. Drill the rivet holes for 2 MS21051-L08 nutplates as per F6124 Nutplate Attachment Detail. These platenuts replace the just drilled out platenuts. They are moved from the ribs to the F6124 Trim Brackets.
