04/06/2009 ... Section 20 Bottom Wing Skins completed steps 2 to 6 on page 20-4. For the Right Wing, I manufactured the Flap Gap Stiffeners W-1021B R /L (the other is for the Left Wing ) as shown in Figure 1. Then clecoed the Flap Gap Stiffeners to the Flap Gap Fairing W-1021-R. Then clecoed Aileron Gap Fairing W-1024-R and final drilled using #40 and #30 size drill bits to the Rear Spar as shown in Figure 2. After final drilling the matching components I deburred and removed the “shinny coating” on all parts then dimpled and primed with DTS Acrylic White primer /finisher. Finally used the correct rivets called out in both Figure 3 and 4. I riveted the Flap Gap Fairing W-1021-R and Aileron Gap Fairing W-1024-R to the top skins and rear spar. Not forgetting riveting the small Flap Gap Fillet W-1021B-R to the end of the Flap Gap Fairing after dimpling for the AN426-3-3.5 flush rivets. Time for just the Right Wing only about 6 hours.
