Assembling the Center Fuselage – 4

I drilled the F-715 outer seat rib to the F-704 bulkhead. I also drilled it to the F-776 centering the centerline on the bottom flange in the holes in the bottom skin. I positioned the top of the rib so the distance between the outside of the web and the outer edge of the seat skin was 0.032” using a bit of scrap for a spacer. This meant that a thin strip of flange was visible past the edge of the seat skin when viewed from the top. I left the seat and baggage skins clecoed in place to help keep the fuselage stiff and straight during the assembly.

Time: 3 hours.
