Elevator assembly 09-15 to 09-17
I set the trim tab aside to allow the Proseal to cure for “a few days” and began working on the main elevators.
After scuffing and cleaning all the skins in the location of the foam ribs and trailing-edge wedge, I began to rivet the ribs and spars of both elevators together. I found that all of these are accessible with the squeezer except the 4 rivets that connect the root ribs to the spar. The instructions have you start by riveting the main spars and tip and inboard ribs, then the hinge reinforcement doublers, and elevator horns with 470-4 rivets. Then, you rivet the counterbalance skins to the tip ribs using flush 426-3 rivets.
