Continuing with work on the Landing Gear Service Bulletin. Removed the 2 outboard most cushion clamps that attach the F-1204Y Wire Run Conduit to the Center Section Assembly. Using a step drill, drilled 3/8 holes in the F-1276 Bottom skin. Match drilled holes from the bottom through the Center Section Assembly. Also match-drilled holes through the F-1270A and F1270D Side Skin Doublers into the left side of the Fuselage. This SB work is taking a lot of time. It was slow drilling through side skin even with brand-new drill bits.
