I FInished drilling both left and right upper spar flanges as well as the skin outboard and center main skin overlap on the right wing. I pulled the right double main rib to transfer holes from the inboard rib to the ourboard rib at station 69.0. Next session I will mark and drill the holes it the rib and transfer #40 holes from the interior of the right wing. Once I get the holes transfered I'll drill them up to #30 from the exterior of the wing. BTW- I got a nother step done on my instrument rating tonight as well. 8 more building days until KOSH!
