I deburred the seat ribs today and dimpled the inboard ribs for the tunnel cover nutplates. The seat floors were then clecoed in place. The floors are riveted using LP4-3 blind rivets according to the plans. I was able to rivet the aft line of rivets along the F705 bulkhead for both seat floors today.
Ribs deburred, Seat floors clecoed, Aft edges riveted to F705
