 FUSELAGE - DESCRIPTION AND OPERATION
____________________________________
 1.  General_______
 A.  The fuselage is a semimonocoque structure consisting of skin reinforced by circumferential frames and longitudinal stringers. Major fuselage components are illustrated in Fig. 1.
 B.  A typical section through the fuselage consists of an upper oval lobe and a lower oval lobe which intersect approximately at the floor level. At the intersection the fuselage is reinforced by transverse floor beams. Above this floor structure, which extends from the front pressure bulkhead at body station 178 to the rear pressure bulkhead at body station 1016, the upper lobe of the fuselage encloses the cabin and is basically a continuous shell, with cutouts in the skin for doors and windows. Below the floor the continuity of the lower lobe, which encloses the cargo compartments, is interrupted by several major structural features: the nose landing gear wheel well, the cavity for the center wing box and the main landing gear wheel well. Aft of the rear pressure bulkhead the floor is discontinued and this section of the fuselage, which tapers towards its aft end, supports the vertical fin, the horizontal stabilizer, a tail skid and contains a compartment with fireproof walls for the APU.
