Tail Cone

Note: Now the riveting starts. The step below has you clecoing it together and riveting. I am going to try to do it a little different. I want to do as much back riveting as possible so I am going to back rivet the Bottom Skin to the Bottom Stiffeners first. I don't know exactly how it will work but will figure things out as I go.

Step 1:  As described on Pages 10-7 through 10-9, Cleco together the portion of the tailcone shown in Figure 1 ( for clarity, the F-1073-L Side Skin and F-1047 Stiffeners attached to it are not shown). However, for now, don't Cleco in place the F-1028 Baggage Bulkhead Channel  the F-1029 Bellcrank Ribs. (Leaving the Bellcrank ribs out improves access to the F-1007 Frame when riveting it to the F-1078 Forward Bottom Skin.) Cleco both F-1032 Longerons to the skins, Frames, and bulkheads.

Now begins the task of riveting the skins. Any rivets associated with the skins can be found on Pages 10-25 and 10-26. DO NOT Rivet anything to the F-1006 Bulkhead while completing the remainder of this section. The F-1006 Bulkhead is riveted when the tailcone is attached to the forward fuselage in a later section.

Step2:  Rivet the F-1047 to the F-1078 Forward Bottom Skin. When riveting the stiffeners to to the skins, rivet the tabs of the frames and bulkheads which lie behind the stiffeners as well. Note: It turned out looking quite nice. A couple of problems requiring drilling out rivets, mostly caused by not having the bucking plate firmly below the rivets.

Step 3: Rivet both F-1073 Side Skins to the Stiffeners, frames and bulkheads. Start riveting at the top of the skins (don't  river the F-1032 Longerons). then work down and around the bottom radius of the skins. Note the steel bucking plate (not visible)  needs to be placed carefully below the rivets being bucked. If it is not it will dent the skin.

 

Step 4:  Rivet the F-1078 Forward Bottom Skin to the frames and bulkheads.

Step 5:  Rivet the bottom edges of the F-1073 Side Skins to the F-1078 Forward Bottom Skin.

Step 6: Rivet the F-1079 Aft Bottom Skin to the F-1011 & -1012 Bulkheads, the F-1073 Side Skins, and to the F-1078 Forward Bottom Skin.

Step 7: Rivet the F-1055-L & R Rudder Stop Skin Stiffeners to the F-1073 Side Skins. Rivet the stiffeners to the F-1056 Rudder Stop Brace using AN470AD4-4 rivets.
