04/12/2009 … Section 20 Bottom Wing Skins ....Page 20-5 step 11. With the Right Wing Assembly in the cradle I laid the dimpled and primed W-1028A Wing Box J-Channel Stiffener into the rib notches and then clecoed the dimpled and primed W-1005-R Bottom Inboard Wing Skin to the bottom flanges at the rear spar in preparation for being riveted. Then I used some stainless wire as in the previous step and tied back the aluminum W-1005-R Bottom Skin so I could reach the rivets at the back spar flange. This worked fine except for some of the rivets at the top or at the back flange that was almost impossible to reach. However the J-Channel W-1028A Stiffener was easy to rivet and the final three “cells” or Wing Ribs toward the Wing Tip Right was and easy riveting task. Now I only have the final drilling, dimpling and riveting of the nut-plates to the three Access Covers. Time about 8 additional hours for the Right Wing only, for a total of 12 hours to rivet both Wing Bottom Skins Right.
