3/22/2009 … Page 20-5 steps 1 to 7 I am building the regular X-10 wing so I skipped the Quick Build steps and just completed the necessary steps. I began by placing the previously drill J-Stiffener Channels W-1028A and W-1028B into the j-stiffener cut-out in the wing ribs and then clecoed the Bottom Skins W-1004L (Inboard) and the W-1005-L (Outboard) to the Ribs and J-Stiffener Channel. Then final drilled #40 all the common holes between the W-1004-L and W-1005-L Bottom Skins and the W-1028A and W-1028B Wing Box Stiffeners and the Wing Ribs. Final Drilled #19 the screw holes for the nut plates then after I was satisfied that no holes were not skipped I dis-assembled the Bottom Skins and J-Stiffeners. Time about 2 hours for the Left Wing only.
