The Bulk door is attached with two hinge arms on the related hinge fittings of the fuselage. It has a balance mechanism to decrease the force necessary to open the Bulk door to the inner side. This mechanism keeps the Bulk door open so that it can not fall down when it is not fully opened. The door handle mechanism operates the locking shaft which locks or releases the Bulk door. The locking shaft also operates the latch assy which safeties the Bulk door in its fully open position.
A proximity switch of the door warning system monitors the locked condition of the Bulk door. This switch sends a signal to the Electronic Centralized Aircraft Monitor (ECAM) System which gives a warning in the cockpit.

A. Door Structure
The primary structure of the Bulk door includes horizontal beams and vertical spars which are made of aluminum alloy. The inner and outer skins, also made of aluminum alloy, contain the primary structure. All components are riveted together to give the Bulk door its rigidity. All rivets and joints in the skins and door structure are sealed to give a pressure-tight outer surface.
The outer skin has a cut-out to rivet the housing of the door handle mechanism to the structure. This housing has a recess for the external door handle to get a continuous surface with the outer skin.
A liquid drain device is installed in the lower beam between the seal and outer skin. On the ground, the drain opens to let the liquid out. During the flight, the drain device closes because of the differential pressure.
