Tail Cone - Component Location3. Description
A. General
The tail cone is made of frames, stringers and skin plates which are riveted together. The access door beams and the support struts increase its structural strength. The tail cone has an inspection compartment and an Auxiliary Power Unit (APU) compartment. You can remove the tail cone from the aircraft as a single unit. It is not pressurized during flight.

B. Component Description
(1) Fittings
The tail cone has:
The tail cone has:
- four main attachment fittings, with two diagonal support struts, installed on the forward frame FR78. These fittings connect the tail cone to the fuselage,
- two framework fittings on the forward frame FR78. These permit the inspection of the horizontal stabilizer bearings with the tail cone installed,
- a fail-safe fitting on the top side of the forward frame FR78. This takes the load if one of the main attachment fittings fail,
- seven APU attachment fittings for the installation of the APU and it's related equipment,
- hoisting points for the removal and installation of the tailcone.
(2) Firewalls
The APU compartment is a specified fire zone and firewalls close the compartment on all sides. The firewalls are made of titanium sheets. The firewalls have cutouts for the APU related components and equipment.

(3) Service Frame
The service frame is a box made of aluminum-alloy sheets. It is part of the APU air intake system. A honeycomb panel with a safety walk surface is attached to the top of it.

(4) Maintenance and Access Doors
A maintenance door (314AR) and two access doors (315AL and 316AR) are installed in the lower surface of the tailcone. They give access to the APU and its related components.

(5) Over-pressure Release Door
The over-pressure release door releases the pressure in the tail cone if there is a sudden increase in pressure. The door closes automatically when the pressure decreases.
