Protected rear spar with pieces of wood at the locations where the straps intersect the rear spar. Clecoed all remaining holes that attach Fuel Tank and baffle to spar . Match-drilled #40 any remaining rivet holes attaching T-701-L Fuel Tank skin to ribs and baffle secured fuel tank to wing assembly using two rachet-type strap fasteners. protected rear spar with a piece of wood at the locations where the straps intersect the rear spar.

Match-drilled #19 the W-723 Leading Edge-to-Fuel Tank Joint Plate for 8R8 screws using T-701-R screw holes in skin as guide. Placed 5/32" clecos in each new hole. Disassembled outboard Leading Edge from spar to reveal outboardmost T-703R Tank Rib and its corresponding outboard attachment Z-Bracket. Used Cleco clamps and existing 1/8" holes to secure T-703R rib in place. Match-drilled #30 the 5 holes that attaches the rib to the Z-bracket using the tank rib aft flange holes as a guide with a 12" drill bit with a drill bit stop at the tip to avoid accidental drilling into the spar. Final drilled the remaining holes in the same rib to #30. Placed clecos in all holes to secure the rib and baffle to the z-bracket. Repeated the step above on the inboardmost T-703L tank rib with the holes not previously match-drilled.
