Drilled correct holes in the lower trailing edge of the right skin doubler and fitted the doubler. As on the left, I needed to trim material near the aft root to clear screw heads, and the skin around the pivot areas for clearance while folding the wing.
Installed the locking handle and fitted the retaining pins W14-10 to check for fit and clearance. I'll need to trim some material around the locking handle where it rubs the skin.
