** ON A/C NOT FOR ALL
1. General
The aft cargo hold is below the passenger compartment in zone 150/160 between the fixed partitions FR47 and FR65. A divider net divides the aft cargo hold into separate compartments. They are known as cargo compartments 3, 4 and 5. The cargo compartment 5 is also known as the bulk cargo compartment. The total volume of the aft/bulk cargo compartment is 989 ft.3 (28.005 m3).
The aft cargo-compartment door, between FR52A and FR56, gives access to the cargo compartments 3 and 4. The bulk cargo-compartment door, between FR60 and FR62, gives access to the cargo compartment 5.
The aft/bulk cargo compartments have:

3. Description and Operation
A. Sidewall Linings and Ceiling Panels
The sidewall linings and ceiling panels in the aft cargo hold prevent damage to the aircraft structure. They are made of flame-resistant synthetic material and permit fast decompression. The sidewall linings and ceiling panels are attached with quick-release fasteners to:
The sidewall linings and ceiling panels in the aft cargo hold prevent damage to the aircraft structure. They are made of flame-resistant synthetic material and permit fast decompression. The sidewall linings and ceiling panels are attached with quick-release fasteners to:
- The support struts
- The cross beams
- The cargo compartment brackets.
B. Ceiling Panels with the Decompression Function and Sidewall Panels with the Decompression Function
Ceiling panels with the decompression function (blow out) are part of the cargo compartment linings. If the decompression occurs, the new lining panels fasteners will release the panels in the cargo compartment. The pressure in the venting area, between the cabin and the lower deck will be the same.

C. Air Conditioning Inlets and Outlets
The sidewall linings and the fixed partition FR65 have cutouts (inlets and outlets) for the air conditioning of the aft cargo hold. The air conditioning system moves air into the aft and the bulk cargo compartment and keeps it at specified temperatures.

D. Bulk Loading Placards
Placards for bulk loading instructions are located on the ceiling in the aft and BULK cargo compartment. The placards tell the minimum clearance allowed between the bulk cargo and the cargo compartment ceiling. The clearance between the bulk cargo and the compartment ceiling must be kept to prevent an inadvertent operation of the:
- Smoke detectors,
- Discharge nozzles of the fire extinguisher system.
Also to enable a correct function of the rapid decompression panels.
The clearance must be 51.0 mm (2.0079 in.) minimum.

E. Smoke Detector Panels
The aft and the bulk cargo compartments are completed with the smoke detection system. The ceiling panels have therefore two cutouts for the smoke detector panels. They are installed at the center of the ceiling panels between FR52 and FR53 and between FR62 and FR63.

F. Access Panels
The sidewall linings installed on the left and right side of the cargo compartment have cutouts. The cutouts are between the FR47 and FR48. The cutouts are covered with access panels. The access panels are attached to the sidewall linings with quick-release fasteners.
The access panels gives access to the compress air bottles and to the pressure gauges of the escape slide system.

G. Rapid Decompression Panels
Rapid decompression panels (blow in and blow out) are part of the cargo compartment linings. They are installed in the cutouts of the ceiling panels and the lateral right sidewall-linings at FR52A and FR56. Catch assemblies hold them in the cutouts. The rapid decompression panels are sealed to the ceiling panels and to the sidewall lining with adhesive tape (Material No. 05-066).

NOTE: If it is necessary to repair a decompression panel, refer to topic 25500008.
H. Divider Net and Door Net
There are two types of nets installed in the aft cargo hold. The divider net at FR59 divides the cargo hold into the aft and the bulk cargo compartment. The divider net at FR50 divides the aft cargo compartment in two sections. The door net prevents damage to the cargo compartment door. The door net and the divider net are attached to the tie-down and net attachment points.

I. Tie-Down and Net Attachment Points
Screws attach the tie-down and net attachment points to the fuselage structure. These attachment points are used for:
Screws attach the tie-down and net attachment points to the fuselage structure. These attachment points are used for:
- The attachment of the door and divider nets
- The attachment of the straps which hold large or small items of bulk cargo.
J. Loading Area Light
The loading area light is a spotlight and is installed in the ceiling panel at the forward cargo-compartment door. The intensity of the loading area light permit persons to read labels on equipment near the cargo compartment door.

K. Cargo Compartment Lighting
The aft cargo hold has a lighting system with the neon tubes and it is installed in the center of the ceiling panels. Toggle switches are installed in the aft and the bulk cargo compartment doors to control the lighting system.
