3. Description
___________
The AFT cargo- compartment door (referred to as cargo door) is a hollow
alloy construction with a structure of sheet metal and machined parts.
The door-to-fuselage connection is of piano hinges which transmit the load
of the cargo door to the fuselage.
To adapt the belly fairing contour to the fuselage contour the cargo door
has a fairing mounted on the forward section.

The latching hooks of the manually operated latching mechanism keep each cargo door in the closed position. The lock cams of the locking mechanism engage with the latching hooks when the cargo doors are correctly locked.
To show this condition there are indication windows in the access panel of each cargo door. The green mark on each lock cam shows that the locking
1EFF : ALL 1 52-32-00Page 14 1 1 Aug 01/05 1 1 1CES 1 mechanism blocks each latching unit in its latched position. The red marks show that the latching units are not blocked and satisfactory.
When the cargo door is locked, the door seal makes the related cargo compartment pressure-tight. To balance the difference in pressure on the ground and in the cargo compartment, there is a vent door in the cargo door. This spring-loaded vent door opens inboard and remains in this position until the cargo door is correctly locked.
The interlock mechanism blocks the latching mechanism in the unlatched position when the cargo door is not closed. Then the door handle is not movable and the latching hooks stay in the lifted position. The door actuators use hydraulic pressure from the door hydraulic system to open and close the cargo doors. They have an internal locking mechanism to keep the cargo door safely in the fully open position.
The proximity switches of the door warning system (circuit WV) monitor the closed and locked condition of the cargo door. They send a signal to the Electronic Centralized Aircraft Monitoring (ECAM) system when a cargo door is not locked. Then the master caution lights in the cockpit come on and the data is shown on the DOOR page of the ECAM display.
The external indications which show that a cargo door is not correctly
locked and latched are:
-
the vent door stays in open position,
-
the door handle stays away from the outer contour of the cargo door,
-
the red mark of each cam lock is in view through the indication windows.
