Worked on rigtht and left Rib #1 (inboard ribs). Modified for ease of attaching control rods by removing the metal between the flanged holes. Per Kerry Fores, no need to add any riveted angles; just flange all around the edges. I used snips and a flanging tool to do the job.
Also mounted the two gussets (W15-06 and W15-07) on these two ribs and trimmed top and bottom per the plans to provide clearance for the spar caps.
