 General

_______ The power plant is installed in the rear fuselage aft of the passenger compartment. It occupies the tailcone, the rearmost portion of the fuselage. The tailcone has been fitted with a fireproof compartment to house the APU. Peripheral systems are installed both in the APU compartment as well as to the front and rear of it. Doors permit access to all components of the power plant.

 System Description

__________________
 A. Power Plant (Ref. 49-11-00) The central component of the power plant is the APU. It is installed in a fireproof compartment between FR80 and FR84 (Ref. 53-58-00). The access doors 315AL and 316AR (Ref. 52-42-00), which together are the lower compartment wall, permit installation, servicing and removal of the APU.
 B. APU Mounts (Ref. 49-12-00) The APU is positioned in the tailcone structure by 7 suspension rods. These are attached to one bracket each on the roof of the APU compartment between FR80 and FR83. Three vibration isolators, installed between the suspension rods and the APU, reduce the transmission of vibration and shocks from the APU to the aircraft structure and vice versa. Brackets attach the vibration isolators to the APU.
 C. Fire Seals (Ref. 49-13-00) For fire protection purposes, the APU is encapsulated within the A/C. This has been accomplished by providing a dedicated compartment within the tailcone. The APU and most power plant systems are installed within this compartment. Only the exhaust system and the air intake extend beyond the compartment, thus the affected fire wall cutouts incorporate additional sealing.
 D. Air Intake System (Ref. 49-16-00) The air intake system provides ambient air of sufficient quantity and quality to the APU. Its major components are:
 -a diverter,
 -
an air inlet (including actuator-driven flap), and

 -
an air duct.

 E. Power Plant - Drain System (Ref. 49-17-00) Various APU components, at which waste fluids (fuel and oil) may occur, incorporate provisions to collect these. In addition, the exhaust system is exposed to rain water and cleaning fluids. For safety and operational reasons, all these fluids are collected separately and drained overboard through the APU compartment drain mast. The APU compartment itself is designed such to permit all fluids occurring to gather at the lowest point, from which they are discharged overboard through the drain mast.
