Started the day off by drilling outall the nutplates I set a couple days ago in the tunnel between the seat floors. Realized the aft seat floors needed to be riveted in with them. Deburred the aft seat floors and riveted them in. Began fitting and preparing forward seat floors. Realized I should have set the three nutplates on each outside rib before riveting in the aft seat floor. Had a difficult time riveting in the nutplate at the bottom of the angle of teh rib nearest the aft seat floor. Took way longer than it should have but I got it done. Clecoed in the forward seat floors and began work on the tunnel cover supports. Fabricated the F741A's as indicated in the plans. Also layed out the tunnel cover nd bent the front end as indicated. Measured and drilled supports on the lower flanges. Clecoed supports in placed cover on top and drilled forward hole onto F939. Riveted the tunnel cover to the supports. Riveted in nutplates onto forward seat floors. Installed forward floors with some but not all screws. Began work on left side seat back. Cut all four upright angle supports to length. Trimmed left side supports as shown on drawings an deburred.
