Brief Description: Drilled and dimpled nutplates for aft seat floor
Decided to install nutplates for a removable seat floor (fwd and aft). Thanks Christoph for the tip. Drilled, deburred and dimpled the seat ribs for CS nutplates for #8 screws. Hat to leave out the one-winged nutplates, didn't have any. Next: Drill and dimple the corresponding seat skin holes.
