Worked on the Right Wing wing locker. Found out that I had Rib 6W6-4 mixed up with the left wing, so it was in backwards for the wing locker. Lucky for me, I had only clecoed the left rib to the left wing frame, and had not drilled the skin holes yet. I wasn't so lucky on the one I installed incorrectly in the right wing. I will probably have to order a new one for the left wing, unless the holes align.
I am also out of "L" , so will have to get that at least.
I will lock down the wing and try to get the nose skins fitted next time.
