Put L/H leading edge skin in fixture and clecoed the four W-709 ribs, It was really easy using the fixture to hold the skin in the right shape to get the nose ribs clecoed in place. Removed the leading edge from fixture and clecoed it onto L/H forward spar. Back drilled the W-408-1 rib using the spar for a guide. Clecoed the W-709 ribs onto the spar. Used the skin as a guide to drill the W-408-1 rib after I marked the holes on rib to get the spacing so I would know where to place the flutes. Prepared the W-423 joint plate. Marked the W-709 ribs #1 through #4 from the inboard to the outboard so I can put them back in same place, when its time for final assembly.
