10 Aft Ribs (SNX-16-01L,O1R, 02, 03, 04, and 05) were modified according to the plans for gussets to be attached. Once that was completed the rib gussets were located, drilled and cleco'd. Everything was disassembled and deburred. A coating of Zinc Oxide primer was put on the mating surface of the Aft Ribs. Once dry, the gussets were re-cleco'd and then riveted in place.
