Brief Description: Finished mounting flaps and installed a wing skin
Drilled the holes for the RH flap hinge wing side half using the same method I used on the LH side.
Cut a stiffener for the LH wing skin to fit just aft of the pitot mast. The purpose is to reduce flexing in the skin resulting on airloads on the pitot and mast. I used an extra fuel tank stiffener that was left over from the set I had to order after I screwed up one of the tank stiffeners.
Located the stiffener on the skin and match drilled through the skin. Deburred, scuffed, dimpled cleaned and primed the stiffener and corresponding location on the skin. Backriveted the stiffener to the skin.
