Today I made new bottom flanges for the F-724 vertical baggage side ribs (photo1), removed the old flanges, installed the new ones, then drilled them to the bottom of the fuselage (photo 2).
I then removed the forward bottom skin for better access to the F-601J engine mount angles on the firewall. I marked and pilot drilled the angles to #40 for attaching the center F-772B floor stiffener angles (photo 3). I'll replace the floor and stiffeners before final drilling to #30.
