Assembled and fastened ribs to main spar Only one issue to note. On rib 5 the top rivet needed to be removed and replaced. The removal process caused a double hole (figure eight). The new rivet didn't set correctly because of the larger oval hole. I elected to use an MSP-42 blind rivet in this location. (See photo) Fitted and fastened the rear spar. Cut and drilled the wing-walk doubler. Fitted the top skins and the doubler to the wing. Mounted wing in wing stand.
