I had to drill out one of the F804H rivets as the shop head was not well formed. Then I removed the skin pannels and dimpled the skins for the four rivets at the F806 rear spar. The AN426 aft of the F806 is going to be difficult. I'm thinking I may be able to position a dimple die in a heavy bucking bar behind the rib and use a hammer to drive the die into the rib. I'll need assistance to perform this but this may be my only way to dimple this so late in the game. I'll have to perform this to the left side as well.
