Brief Description: Mid Fuselage - Position side cargo rib & Drill Ski
I positioned the outboard cargo rib. I flutted it to be flat and to match the bend on the bottom skin. The forward part of this rib needs to be flush with the skin. The aft straight side does not. I clamped in the straps made earlier.
I picked up the whole mid fuselage assembly and placed it upside down on the floor for drilling. I drilled all the holes except the forward row and aft row per plan/drawing.
