Worked on getting the left flap travel ready as the right one is. Mike Cencula came over and we started putting in rivets. We got the nose ribs in and noticed the ribs that a few of the dimples on the ribs that were in between the flap track ribs and the center flap connect ribs split. It was only a few but it was a show stopper until we could figure out why. It looks like a call to Glassair is in order.
