A. Open Mode
To open the Bulk door from the external side, press the button of the external door handle. This releases the handle lock mechanism and the external door handle moves from the recess. This position makes sure that the external door handle can operate the locking shaft. The internal door handle operates the locking shaft directly but does not operate the retracted, external door handle.
To release the closed Bulk door, put the internal or the external door handle to its "OPEN" position. This movement causes the lever assy to operate the pushrod which turns the locking shaft. Thus, the front and rear barrel locks disengage from their latch spigots and the Bulk door is manually movable. The operation of the external door handle causes the internal door handle to move also, but in the opposite direction.
The disengaged rear barrel lock does not operate the spring-loaded lever assy of the latch spigot. This causes its related target to operate the proximity switch 50WV which sends a signal to the ECAM system. Thus, the ECAM system gives a warning in the cockpit to tell that the Bulk door is not locked.
Move the Bulk door inboard until the latch spigots on the fuselage frame come in view. The balance mechanism holds the Bulk door in this position.
Put the internal or external door handle in the "LOCKED" position again. This moves the locking shaft which operates the spring rod to safety the overcenter position of the hook. After the outboard operation, push the external door handle into its recess again.
Then move the Bulk door manually inboards until the hook engages with the hook arrester of the fuselage crossbeam. This operation safeties the Bulk door in its fully open position.
B. Close Mode
To close the Bulk door from the external side, press the button of the external door handle. This releases the handle lock mechanism and the external door handle moves from the recess. This position makes sure that the external door handle can operate the locking shaft. The internal door handle operates the locking shaft directly.
R 1EFF : 001-003, 051-054, 1 52-33-00Page 19 1 1 May 01/05 1 1 1CES 1 To release the opened Bulk door, put the internal or external door handle to its "OPEN" position. This movement causes the lever assy to operate the pushrod which turns the locking shaft. Thus, the spring unit operates the hook which disengages from the hook arrester. The balance mechanism prevents that the Bulk door falls down if it is not safetied.
Pull the Bulk door down into the door opening until it is in line with the fuselage contour. Put the internal or the external door handle to the "LOCKED" position. This operation moves the locking shaft so that the front and rear barrel locks engage with their latch spigots. During this movement, the rear barrel lock operates the lever assy and its related target operates the proximity switch 50WV. This operation cancels the warning of the ECAM system in the cockpit.
After the outboard operation, push the external door handle into its recess again.

To release the closed Bulk door, put the external door handle to its "OPEN" position. This movement causes the lever assy to operate the pushrod which turns the locking shaft. Thus, the front and rear barrel locks disengage from their latch spigots and the Bulk door is released. To release the Bulk door from the inner side, use a spanner with a width across the flats of 28.5749 mm (1.1249 in.) to operated the lever assy directly.
The disengaged rear barrel lock does not operate the spring-loaded lever assy of the latch spigot. This causes its related target to operate the proximity switch 50WV which sends a signal to the ECAM system.

After this operation, push the external door handle into its recess again to prevent posible damage during the loading .
