In the corners of the door beams and door frames, there are gaps to drain
condensed water. Two drain valves are installed on the lowest beam of the
pressure-tight structure and drain this water via drain hoses to the
outside. Some drain holes are added in the critical areas of the internal
structure which is painted with a water repellent agent.
Additonal access cover are in the outer skin of the cargo door to get
access to the drift pin asssembly from the outer side.

B. Door Suspension
The connection of the cargo door to the fuselage includes the two halves of the piano hinges and two hinge pins. The outer parts of the multi-section piano hinges are made of titanium alloy and the mid parts are made of aluminum alloy. One halve of the piano hinges is attached to the upper edge member of the cargo door with screws. The related, opposite piano hinge halves are riveted on the upper door frame fitting of the fuselage.
R 1EFF : ALL 1 52-32-00Page 18 1 1 Aug 01/05 1 1 1CES 1 The hinge pins connect the door and the fuselage hinges. The fairings at both ends of the piano hinges hold and safety the hinge pins in their positions.
C. Lining and Insulation
To protect the cargo door against fire, a door lining is installed on the inner skin with quick-release fasteners and VELCRO tapes. This lining is in one section and made of prepreg layers. To protect the cargo door against heat and sound, a self-adhesive insulation mat is attached to the door lining. The mat is made of polyethylene foam.

The proximity switches of the cargo door include a target and a sensor and have a separated electronic system.
The proximity switch 34WV monitors the position of the door handle. The sensor is attached via a bracket at beam 4 near FR55 and the target is installed on the forward egde the door handle.
The proximity switch 32WV monitors the position of the cargo door. The sensor is installed in the door sill area near FR53 and the target is attached on the target lever (part of the switch mechanism).
These two proximity switches send information to the ECAM system when the cargo door is closed or opened (Ref. 52-71-00).

The proximity switch 12MJ is included in the door control system (Ref. 52-35-00). The sensor is installed on the beam 4 near frame FR53A and the target is installed on the control lever of the latching shaft. This switch prevents the hydraulic operation of the cargo door if both parts are not in line.
