I back-riveted the trim access reinforcement plate to the left elevator skin.
I also prepped the trim cover plate and attached it with AN507-6R6 screws.
Finally, I deburred, dimpled and put rivets in all of the skin holes where they are riveted to the stiffeners. It’s too late to rivet these tonight, but I can knock these out quickly tomorrow morning.
Here’s the left elevator skin ready for back riveting the stiffeners.
