Completed riveting on the internal ribs on the flap. Installed theMK-319BS rivets on the bench, then put the flap back in the stand and continued to rivet the end rib on the bottom side. Set every other rivet as before. I could not get the bucking bar on the rivet adjacent to the nutplate, so I drilled this one to #33 and used a MK-319BS pulled rivet as on the right flap.
Used the squeezer for most rivets on the outboard end of the flap. Used offset riveting for the last couple of rivets, but did not get a good set on them (factory head not flush). Prepared to drill and replace these.
