With the shop readied I clecoed the already prepared bulkheads, skins and J-Channels together to form the aft fuselage. I got one of the bulkheads facing the wrong way and had to ttake it almost all the way back to the beginning to correct this. I also found that I had the bottom skin under the tailcone, so I had to undo some more to get that right. But it is now clecoed together properly and should be ready for riveting.
I also pulled out the ADHRS mount kit and will assemble and mount this as part of the aft fuselage assembly.
