More nut plates today. I finished the right side and put the seat and baggage floors in with a couple of screws. There is little doubt that I will have them out again before too long, so I elected just to hold them in place without every screw. I'm sure I will be happy to have the option to remove the floors at some point, but I have to admit I'm getting tired of installing nut plates.
One note for my next project--install the nut plates BEFORE putting the ribs in along the side as access for dimpling and riveting is lousy. Did I just say my next project?
