Brief Description:    Rivet Spar
Riveted the SparCaps and VS1008 Spar Doubler to Rear Spar and Bottom and bottom rudder hinges. Picture #1
The rivets called for the doubler and spar (AN426AD4-7) are the same rivets called for when adding additional thickness of the rudder hinge. I elected to go with a slightly longer rivet, an AN426AD4-8 on the rudder hinge. The top two were the rivets called for and you can clearly see the length was too short.
Going with an AN426AD4-/-8 Corrected the problem.

Same thing done on the middle rudder hinge, although different rivets called for.
AN470AD4-5 and -6 used on hinge brackets.
