Not a lot of time to work today, but I did get deburring, sanding, priming and riveting for the right wing trailing edge fairing box all done, and it's in. Yea! The first photo shows the box all riveted together.

The second photo shows the fully primed inside. You can see the addition of a doubler strip to the inside edge of the vertical part -- to the left in the picture -- where there is no rib flange to support that edge.

The last photo shows the completed box installed on the fuselage. Installation included changing 4-5 rivets to countersunk rivets to better accomodate the rest of the wing fairing strips to come.
