1. General
The main structure of the rear-fuselage is primary, made of aluminum-alloy. It has skin plates, frames, stringers and skin stiffeners, they are riveted together to make the fuselage shell. Top beams and seat tracks, riveted to crossbeams make the cabin floor stronger. Support struts and diagonal braces make the fuselage structure stronger.

Rear Fuselage Main-Structure3. Description
A. Skin Plates
The skin plates are made of aluminum-alloy sheets and stringers which are riveted to them make them stronger. Skin plates are preformed to the contour of the fuselage before they are riveted to the frames.

B. Frames
The frames are the stiffeners that go around the fuselage shell. They are made of aluminum-alloy sections which are formed or machined. Clips, with cut-outs for stringers, are riveted between the frames and the skin plates. Door frames and beams make the frame structure stronger in the area of the aft passenger/crew and cargo compartment(s) doors.

C. Stringers and Skin Stiffeners
The stringers are the longitudinal stiffeners of the fuselage shell. They are made of aluminum-alloy Z-sections which are formed, extruded or machined. They are riveted between the frames and the skin plates. Skin stiffeners make the skin stronger in areas where there are no stringers. The skin stiffeners are riveted to the skin.

D. Crossbeams
The crossbeams are made of aluminum-alloy C-sections which are extruded. They are riveted to the frames. They are the primary structure of the cabin floor. Support struts which are riveted to the crossbeams make them stronger.

E. Top Beams and Seat Tracks
The top beams are the longitudinal stiffeners of the cabin floor structure, they are riveted to the crossbeams. Seat tracks are riveted in pairs to the crossbeams and they are also part of the cabin floor main-structure.

F. Floor Panels
The floor panels are made of honeycomb core which is bonded between Glassfiber Reinforced-Polyester or aluminum sheets. Screws attach the floor panels to the floor structure.

G. Junction Rear-Fuselage/Cone Rear-Fuselage
The junction of the rear-fuselage/cone rear-fuselage is located at STA3365/FR70. At this station the rear pressure bulkhead is installed.
The rear pressure-bulkhead has a frame made of aluminum alloy which is machined. The segments, made of aluminum-alloy sheets, are riveted to the frame to make a pressure diaphragm.
The top part of the frame is made stronger to support the fwd attachment fittings of the vertical stabilizer.

H. Fittings
The fittings let structural parts be directly connected to the fuselage or to the components already connected to the fuselage.
