** ON A/C NOT FOR ALL
1. General
In the lower deck of the aircraft, there are two lower holds (forward hold and aft hold) which are divided into cargo compartments. The forward hold is divided into the forward cargo compartments No. 1 and No. 2. The aft hold is divided into the aft cargo compartments No. 3, No. 4 and the bulk cargo compartment No. 5. A divider net isolates the cargo compartment No. 5 from the cargo compartments No. 3 and No. 4. The forward, aft and bulk cargo compartments have tie-down/attachment points for the door nets and for the nets and straps which keep the bulk cargo in place.

B. Forward and Aft Cargo Compartment
The forward and aft cargo compartments have floor panels and linings. The linings keep smoke in the compartments and prevent damage to the lines and electrical wires. Each cargo compartment has items which make a restraint system. The restraint system permits the loading of loose baggage and bulk cargo in the forward and aft cargo compartments. The divider nets give each cargo compartment loading sections. The forward and the aft cargo compartment have five sections. This permits to load only a part of each cargo compartment.

NOTE: The semi-automatic loading systems in the forward and aft cargo compartments have the same components and operate in an equivalent manner.
Each semi-automatic cargo loading system is controlled from a control panel on the forward and aft cargo compartment doors and can be operated by one man. Electrically controlled power drive units move the unit load devices (ULD) to and from their load positions. The ULD are moved one at a time. Manually operated latches hold the ULD in place.
C. Bulk Loading
The forward and aft cargo compartments have items installed which let load bulk cargo. The items which permit bulk loading are:
Each cargo compartment has tie-down points, attachment points and multiple attachment points. The tie-down points are for the attachment of the straps and/or nets which hold large or small items of bulk cargo. It is always necessary to use the nets and straps to safety all large or small items of bulk cargo. The tie-down points are also for the attachment of the divider nets.
There are four types of divider nets, A1, A2, A5 and C. The divider net A1 has a screen and is installed in the aft cargo compartment only at the FR59. The divider net A2 is installed in the forward cargo compartment at the FR31 and the FR35.2. The divider net A5 at FR50 is installed if the aft cargo compartment is equipped with ACT1. If the aft cargo compartment is not equipped with ACT(s) the divider net A5 is installed at FR47.5. At the FR53 in the aft cargo compartment is the divider net C installed. The divider nets divide the cargo compartments into sections.
The door nets type A and C are installed near the forward cargo-compartment door. The door nets type A and B are installed near the aft cargo-compartment door. The door nets prevent damage to the cargo compartment doors and keep the door areas clear of any bulk cargo. The door nets have stanchions which give them a strong contour. The door nets must always be installed after cargo is loaded or unloaded.
The multiple attachment points are for the attachment of the door nets to the cargo compartment floor. The attachment points are for the connection of the stanchions to the cargo compartment ceiling.
The tie-down/attachment items provide an easy and quick removal and installation of the nets and straps. For the load/unload procedure, the nets are removed/installed as necessary.

D. Bulk Cargo Compartment
The bulk cargo compartment is for passenger luggage and bulk cargo. A divider net isolates the bulk cargo compartment from the aft cargo compartment. The bulk cargo compartment has tie-down points and attachment points. The tie-down points are for the nets and straps which keep bulk loads and luggage in place. It is always necessary to use the nets and straps to safety large or small items of bulk cargo.
The attachment points are for the installation of the divider and door nets. The door nets have stanchions which give the door nets a solid contour.

(1) Rapid Decompression System
The rapid decompression system has:
For the correct function of the rapid decompression system all the rapid decompression catches have to be in the closed position.
The rapid decompression system has:
- A decompression panel
- A frame
- Fastener assemblies.
- Latches
- Springs
- Catches.
For the correct function of the rapid decompression system all the rapid decompression catches have to be in the closed position.
(2) Collapsing Lining Panels
At a specified pressure difference the fastener elements disengage and let the collapsing lining panels move to an open position. Thus lets the air flow between the cabin and the cargo compartment and then the pressure between these two areas becomes equal.
For the correct function of the collapsing lining panels all the fastener elements have to be in the closed position.
NOTE: Each collapsing lining panel is identified with the silver metallic washers.
