Tanner helped me locate and match drill the four F-772B-R/L forward fuselage floor stiffeners. I then drilled them to the F-783B-L/R cover support ribs and the two F-601J angles on the firewall.
Next, I located and deburred the F-724 vertical and F-722 horizontal baggage area ribs. I deburred all of these and then riveted the two K1000-8 nutplates on each F-722.
