Attached nut plates at inboard rib and countersunk screw holes

Riveted the nut plates that will be used to attach the wing attach point fairings. I was able to squeeze all the rivets.

Machine countersunk the corresponding #8 screw holes to fit a dimpled skin.

Clecoed and match drilled the outboard aileron bracket. Then deburred everything and clecoed back in place.

It was a bit too ate in the evening for riveting so that will have to wait until tomorrow. If Remy can buck a few more rivets with me, I should be able to get the stiffeners riveted in and the left wing top skins will be complete!
