There is a relatively large tooling hole on the aft end of the outboard rib that needs to be sealed. I fabricated a small cover plate and match-drilled it to the rib. Both the rib and cover plate were deburred, scuffed for proseal, and dimpled. The final thing I did today was fabricate the anti-rotation bracket for the fuel pickup fitting. I used a unibit to make the 9/16" hole for the fitting.
