Installed the nutplates in the inspection cover hole for the stall warning in the left wing. Started with the right wing skins. Clecoed the skins around the nose , easier when flipping the wing over. I used a tube light to check for "bad" rivets. I found about five rivets from which the mandrel felt out. The flaperon hinges didn't fit between the riveted ribs (I had no problem at the left wing). Had to drill out some rivets to make them fit. Bottom skins ready.
