- Deburred the inside face of the lower aft wing skin
- Reinstalled the lower aft wing skin since I'll need to drill the 8 holes for the other end of the channels for the aileron bellcrank
- Flipped the wing over and updrilled the holes in the aft edge of the upper aft wing skin, through the rear spar (only the holes at the flap location, where there will be no holes for the flap hinges; the other holes in that trailing edge will not be updrilled until the flap hinge is laid out and pilot drilled).
- Unfastened the upper aft wing skin for deburring
