Brief Description: Back-drilled Fuselage Ribs to Top Skin
I started back-drilling the center rib to the skin and made sure that the skin was lined up. I continued to back-drill the skin. After the center area of the skin was drilled and clecoed in place, I placed cargo straps around the fuselage to pull the sides in tight and then drilled down the sides of the instrument subpanel. I finished drilling the skin to the ribs and the subpanel.
