Worked on the Wing root fairing for the left wing. Deburred the fairing, and match-drilled the holes along the wing top. It took a bit of work to "pull" the aluminum fairing around the wing leading edge to the proper position on the wing bottom. Since the fairing has CNC'ed holes, once the fairing is in place, it's a matter of match-drililng to the wing. Then drilled, deburred, and riveted the many nut-plates. The right wing should go easier.
