Step 1: Note I tried back riveting the skins but don't seem to have the hang of it yet. I had trouble getting the ribs to fit tight to the skin, so I decided for now to go back and just buck the top skin rivets.

 

 

Step 2:   Lay the W-1028A and W-1028 B Wing Box J-Stiffeners in into the J-Stiffener notches in the wing ribs. Cleco the W-1002 Top Inbd Skin, W-1003 Top Outbd Skin, W-1027A and W-1027B Wing Walk Doublers to the spars and ribs. Cleco the stiffeners to the top wing skins. Cleco the nut plates that attach along the inboard edge of the top inbd wing skin to the wing assembly (see Figure 1). Check the top outbd wing skin is on tip of the top inbd wing skin.

 

Here is how I prepared the skin for riveting. I had Bill come over and buck the rivets.

Step 3:   Rivet the W-1002 Top Inbd Wing Skin and W-1003 Top Outbd Wing Skin to the W-1028A and W-1028B  J-Stiffeners, ribs, rear spar, and main spar. See Figure 2 and Figure 3 for the rivet callouts. Note: Adjusting the pressure carefully and the tape produced some very nice looking rivets. I got much better results than the row I tried to back rivet as I did not have the skin and rib tight enough to one another and it produced some puckers in the skin on one row.

 
When riveting the inboard most row of rivets, install the nut plates as indicated in Figure 1 to the W-1010-R Outbd wing skin. To assure maximum skin tightness, rivet from the center of each skin outwards towards the root and tip. Do this on both skin saving the double row  of rivets at the lap joint until last.

  NOTE:  DO NOT COMPLETE ANY STEPS ON THIS PAGE UNTIL THE TOP SKINS ARE COMPLETELY RIVETED ON. RIVETING THE W-1014-L OUTBOARD AILERON HINGE BRACET ASSEMBLY ON PREMATURELY WILL REMOVE ACESS TO THE OUTBOARD MOST RIVET ATTACHING THE W-1003 TOP OUTBOARD SKIN TO THE W-1007A-L REAR SPAR WEB.
 

Step 1:   Cleco the W-1014-L Outboard Aileron Hinge Bracket Assembly to the W-1012R TRIMMED Outboard Wing Rib, two places as shown in Figure 1. Cleco the outboard aileron hinge bracket assembly to the W-1007A-L Rear Spar Web and W-1007E-L Rear Spar Doubler Plate as shown in Figure 1.

 
Step 2:   Final-Drill #30 the W-1014-L Outboard Aileron Hinge Bracket Assembly to the W-1007-L Rear Spar Assembly. Match-Drill #30 and cleco the outboard aileron hinge bracket assembly to the W-1012-R TRIMMED Outboard Wing Rib using the hinge bracket as a drill guide. Remove the two clecos holding the hinge bracket to the outboard wing rib and final-drill #30 the holes in the hinge bracket and outboard wing rib.
 
Step 3:   Un-Cleco the W-1014-L Outboard Aileron Hinge Bracket from the wing assembly.
 

Step 4:   Cleco the W-1014-L Outboard Aileron Hinge Bracket Assembly to the wing assembly per Step 1. Rivet the outboard hinge bracket assembly to the wing assembly as indicated in Figure 1.
