The shop was a mess, so I cleaned things up first. I got all of the ribs clecoed into the left leading edge, including the stall warning rib. The top three holes did not line up well with the wing skin holes. By putting one big flute into the rib flange, I was able to bring that hole into alignment. I then clecoed the left leading edge onto the wing spar. Next I retrieved the inboard close out ribs (W424 –L/R?) and figured out from the drawings which went where. These ribs do not have pilot holes for either the rib to skin or rib to spar interface. I marked the approximate skin hole locations on the rib flanges and used that as a guide to flute both ribs to get them flat. The splice plate (W423-L/R) between the fuel tank and leading edge is made from sheet stock as called out on the drawing.
