W17 Aft Root Rib - Right Hand Wing - Fitted the aft rib behind the attach angles and clamped in place. I drilled a few holes for location. I then removed the angles and rib. I clecoed the rib to the angle in the correct position and drilled and updrilled the holes. I drilled the holes for -04 and -05 reinforcement angles. I then riveted all the parts for the aft root rib together. I then installed the aft rib by reinstalling the bolts and rivets that hold it in place on the wing.
