Drilled out called rivet, positioned rudder trim tab, and match drilled to left side of rudder. Removed trim tab and deburred holes (steps 1 through 5).
Masked and primed back of rudder trim tab and corresponding area on rudder with Stewart Systems Ekoprime.
Was ready to rivet tab to the rudder but could not find the called AD-41-ABS rivets. Will need to call Van's and order them to finish this section.
