Sand, deburr and clean reinforcement angle and lower skin. When I lay down skin on the ribs, I realize that centerrib no 1 was in wrong position at main spar end. Drilled out 5 rivets and move it 50 mm inwards. I guess mounting holes are drilled att factory so it can be used at more than one variant. Some bolts has to be removed to craete space for end of rivets. Locknuts now torqued again. Skin is now cleco´d in position and I start rivet tomorrow.
