I'm fitting the F-623 ribs to the mid fuselage bottom skin. I have modified the forward ends as per plans. When I position the rib flush with the edge of the bottom skin the aft hole is not covered by the rib. Obviously there's something I'm not understanding. Is the aft end of the rib also supposed to be modified? Thanks.

Steve,
You need to trim the aft end of the F-623 rib. I could go on about how to do it, but my builders log gives some pics on the following entries:
