Brief Description: Top Wing 16-2 steps 1 to 4 section
12/7/2008 … Beginning with the right wing first and then repeating for the left wing I completed steps 1 to 4 section 16-2. Retrieved the previously created J-Channel Aluminum Wing Box J-Stiffeners W-1028A-Long and W-1028-B (top right) short and placed into the notches of the Wing Ribs. Then remove the blue protective coating of the two skins W-1002 (inboard) and W-1003 Top Skins (out boards) and the two Wing Walk Doublers W-1027A and W-1027B and clecoed to the Main Spar assembly. Then final drilled all the common #40 holes in the assembly as shown in Figure 1 page 16-2. Also final drilled #19, the aft most nut plate holes as shown in Figure 1 then counter sunk the same holes with a #8 countersink install in a micro-stop. Next, I machine counter sunk all the rivet holes that corresponded to the W-1027A and W-1027B Wing Walk Doublers for the head of an AN426-AD3 rivets. Then disassembled the parts clecoed in preparation of step 5 page 16-2. Time about 4 hours.
