Brief Description: LH wing - fitting of top aft skin
1. Flipped wing over and drew centerlines on LH aft ribs. Secured aft spar to PVC blocks as was done for the bottom skin.
2. Removed inside plastic coating from inside of LH top aft skin. Used a soldering iron to remove plastic strips from rivet lines of outside of skin.
3. Applied upper aft skin and wing walk skin to ribs and cleco'd to aft spar. Checked alignment with rib centerlines and corrected as needed. Checked assembly for level and square.
4. Transfer-drilled rib holes to #40 beginning at the center of the aft spar, working forward and outward in a fan pattern, and inserting cleco's as I drilled.
5. Removed cleco's from outer rib and inserted upper aft wing tip skin. Replaced cleco's.
6. Cleco'd wing tip stiffener into place, and drilled remaining attach holes, first to #40 then to #30.
First round of drilling on the top aft skin is done for the LH wing
