ABSTRACT:
A system for converting all or part of a passenger cabin in a fuselage of an aircraft for the carriage of freight, the cabin having internally finished longitudinal walls and ceiling defining an internal cross-sectional profile of substantially uniform cross-section. The system includes a dismountable rigid liner structure forming an enclosure having an external profile receivable within the internal profile of the cabin without contacting the walls and ceiling. It is formed of interlocking components individually small enough to pass through a cargo door in the fuselage and is supported between ends of the cabin solely by releasable anchorages engaging seat tracks installed in the cabin, the liner structure including transverse cargo restraints releasably secured thereto for restraining movement of cargo through said liner structure. The modules form a series of longitudinally connected compartments, each compartment including a truss element and anchors for securing a cargo restraint at its front end, an endmost compartment being closed at an end of the structure by a cabin bulkhead or a substitute bulkhead structure connected to the fuselage of the aircraft in place of a removable cabin bulkhead. The components of the enclosure may be sealed to each other and to the aircraft structure so as to isolate its interior from the cabin in which it is installed and resist the passage of smoke, fumes or flame from the enclosure to the cabin.
