Step 1:  Flip the tail cone over on the sawhorses. Cleco the F-1011 Bulkhead and the F-1079 Aft Bottom Skin to the F-1078 Forward Bottom Skin and F-1073-R Side Skin as shown in Figure 1. Cleco the F-1012 A & B Bulkheads to the aft bottom skin and the side skin.

Step 2:  Position the remaining F-1047C, D, and E Stiffeners in the notches of the frames and bulkheads, then cleco the F-1073 Side Skin to the frames and bulkheads, to the F-1078 Forward Skin, and to the F-1079 Aft Bottom Skin.

Step 3:  In the same manner as the F-1047C-R,D-R, and E-R Stiffeners on the F-1073-R Side Skin were located and match drilled, locate and match drill the F-1047C, D and E Stiffeners on the F-1073-L Side Skin. These stiffeners are now dedicated left parts.

Step 4:  Locate the F-1055 Rudder Stop Skin Stiffener and split it between the notches to form the individual parts shown in Figure 2.

Step 5:  Cleco the F-1055-R & L Rudder Stop Skin Stiffeners to the F-1073-R &-L Side Skins respectively as shown in Figure 3.

Step 6: Make the F-1056 Rudder Stop Brace from a length of AA6-063 X 3/4 x 3/4 angle using the dimensions in Figure 4.

Step 7:  Position the F-1056 Rudder Stop Brace against the F-1012A Bulkhead web, centered between the two F-1055 Rudder Stop Skin Stiffeners as shown in Figure 5. The angled flange of the brace rests under the flanges of the stiffeners. 

Step 7a:  Make sure the tailcone is not twisted by placing a level across the top of the F-1073 Side Skins in two palaces (near the front of the side skins and at the F-1012 Bulkhead), then clamp the brace to the stiffeners.  

Hold the brace against the bulkhead, then match drill the four holes of the bulkhead into the brace (watch your fingers) using a #40 drill. Cleco as you drill.

Remove the brace, deburr the holes and clear away any chips

Then drill the holes in each stiffener into the brace using a 12" long #30 drill.
