The work session started by clecoing the longerons to the tailcone side skins, then with the assistance of Lisa I clecoed those to the fuselage. Added bulkheads and finally placed the large bottom skin in place. The bottom skin was a huge challange. We had to take it off and on a couple of times untilwe ended up with the proper alignment. Even with that it was a hole by hole, cleco by cleco process down the right side to get things seated properly.
