Just for fun, and to take a cool under construction pic for the coworkers to gawk over, I test-fit all of the main and leading edge ribs to my left wing spars tonight. Everything looks good, except the two most inboard W-909-L leading edge ribs. It looks as if the upper- and lower-most holes on the main spar have been pre-drilled too closely to their neighbor holes, and thus do not match with the rib holes. See pics below. The rib holes are evenly spaced, but the two upper and lower most spar holes are too close together. You can just barely see it, but the upper-most spar hole looks through onto the red ID stripe the factory puts on the rib.
My instinct is to match-drill new holes into the rib to match the spar's holes. My best guess, since the upper hole looks onto the red stripe, is that the new holes would be centered between the two existing holes. But has anyone else experienced this? Does this seem okay to just drill new holes in the rib's flange?
