I finished up page 21-02 and started working on page 21-03. This involved buffing the edges of the flap nose ribs with my Scotch-brite wheel to make the tabs on the leading edge contour smoother. Then there was some match drilling and final drilling of the "Inboard Rod End Rib Subassembly" and "Outboard Rod End Rib Subassembly". The "Left Hinge Pair Rib Subassembly" (and Right) involved more clecos and match drilling.

Throughout the last couple days, I've been trying to focus on first building just the left side flap and just using parts ending in "-L", but I started to realize that the directions were actually needing me to use parts that had a "-R" suffix even on the left side. So this meant pulling out more of the parts that I had been setting aside for later and deburring/prepping them so that I would have all of the needed parts for the left flap. This just means that I'll have less prep-work to do later when I start on the right flap.

Moving onto a new part: the main ribs for the flap. I started by removing their blue plastic and labeling them, as usual. Then used pliers to eliminate the "pucker" in the edge cutouts, caused by incomplete bending at the factory.

What's next? The next step tomorrow will be to cut off an extra tab on these ribs, but I think I will need to use a Dremel cut-off wheel since my bandsaw wouldn't be able to cut just one side of it. I'll have to do some research to see what other people do here.
