We got back in the groove today and made a lot of progress on the left fuel tank. We started by match drilling the fuel tank attach brackets to the main spar and the skin to the stiffener that attaches the tank to the wing leading edge. Next we match drilled the fuel tank (lots of holes to drill and clecos to move). We then split up and worked on a few tasks simultaneously. While Darren was machine countersinking the fuel tank skin to the rear fuel tank baffle, Scott was cutting a few different stiffners and brackets for the tank. We next started working on attaching the plate nuts to the fuel tank attach brackets. As with all plate nuts we match drilled, deburred, countersunk, prepped, primed and then riveted the plate nuts. Our final step was to rivet 3 more plate nuts to the main spar.
