Wing prep finished: 4.9 hours

Finished remaining rib and aft spar deburring and dimpling. Deburred and dimpled upper outboard skin. Primed all countersinks. Drilled pilot holes for fuel return line in right tank ribs. I decided on fuel return linesĀ  in case the fuel injection system I choose in the future requires this. If not I can cap the lines at the tank fittings.
Ready for assembly!
