As you recall from my last post, I started the Rear Spar riveting process last night. During today’s session, I finished installing all the remaining rivets. The first picture shows the completed Rear Spar Reinforcement Fork and Rear Spar Doubler Plate riveted to the Rear Spar and Wing Ribs. A combination of AN470AD4-6, AN470AD4-8, and AN426AD4-8 rivets were used in this location.
This picture shows the completed Rear Spar Doubler Plate (Inboard), Rear Spar Doubler Plate (Outboard), and Aileron Hinge Bracket Assembly riveted to the Rear Spar and Wing Ribs. A combination of AN470AD4-4, AN470AD4-5, AN470AD4-8, and AN470AD4-9 rivets were used in this location. This installation also completes (complies with) Service Bulletin 16-03-28. SB-16-03-28 was issued for “cracking of the wing aft spar web at the inboard aileron hinge bracket attach rivets”. The appropriate materials and instructions were supplied with the Wing Kit when I originally ordered it from Van’s.
There were two small addtional steps required for me to completely finish Seciton 14. First, I had to install 14 (7 on the Upper and Lower Main Spar Flanges) AN426AD3-3.5 rivets. Here is an example of three of the rivets installed. All 14 of the rivets are “in-line” with where the fuel tanks will attach to the Main Spar. I suspect the Fuel Tank Skins will cover these rivet locations after installation.
Secondly, the six AN470AD4-4 rivets had to be installed that attach the Torque Tube Support Bracket Assembly to the web of the #1 Wing Rib.
