Today, I completed Riveting the ribs on the lower tank skin. I then worked to rivet the rest of the wing, including the doublers for the autopilot, the strut hold down, and the inner control tube bearing. I also installed the fuel drain fitting. All that is left on the lower tank skin are the fuel tank inspection covers. I then flipped the wing so I can proseal the rivet tails etc. inside the fuel tank. So, tomorrow is another proseal day :)
