PASSENGER DOORS/LOCKING MECHANISM DESCRIPTION LOCKING HOOK

LOWERING SHAFT

The locking hook engages on a roller mounted on the door frames. The door is locked by a hook.

The door cannot be lowered in the open position while beyond the door frame. The lowering shaft mechanism locks the control handle handle to prevent the door from being lowered when not in contact with the door sill.

SAFETY PIN A safety pin blocks the door even if a double mechanical mechanical failure in the locking mechanism and the lifting mechanism occurs. The safety pin prevents any upward door movement. LOCKING SHAFT The locking shaft is locked in an over centered position. An arm on the locking shaft forms the visual locking indicator. The locking shaft is connected to the hook by a rod and bellcrank.

EMERGENCY CONTROL HANDLE The emergency control handle is located far from the inner control handle. It is connected via rods and levers to the girt bar actuating mechanism. GEAR BOX The shaft of the door central handles is coupled via a gear box so that the outer-handle will not move when the door is lifted by operation of the inner handle. The gear box is connected by rods to the locking shaft and lifting lever.

SPRING ROD DISARMING MECHANISM

EMERGENCY EXIT DOORS PRESENTATION LOCKING SYSTEM The door is locked by a hook located at the top of the door. Door locking is monitored on the ECAM by proximity switches. One inner handle and one outer handle handle operate the door locking mechanism. The shafts of these handles are coupled via a control mechanism which disarms the slide release mechanism when the outer handle is moved. It also prevents the operation operation of the outer handle if the inner handle is moved. EMERGENCY SYSTEM The emergency system consists of a slide control handle controlling the escape slide release mechanism, a damper and emergency operation cylinder, an escape slide/raft packed in a container fitted in the fuselage under the door and an inflation reservoir located above the door.

- In DISARMED mode, the damper and emergency operation cylinder damps the door movements.

- In ARMED mode, the damper and emergency 1

EMERGENCY EXITS / DOORS OPERATION NOTE : In this module module the EMERGENCY EMERGENCY EXITS / DOORS DOORS OPERATION is described on the A320 but the principle is the same for the A319. OPERATION Two emergency exits are located over each wing. The exits can be opened from the outside outside and the inside. Inside opening instructions instructions are placarded on the exit frame. To open an exit, the cover flap must be removed. The "slide armed" indicator illuminates white immediately. To unlock the latch mechanism, the control control handle must be used. Pull down the control handle handle and pull exit top inwards. With free hand grasp the lower grip mould and lift exit. Turn exit inward and throw it out away from opening. Should the exit opening not initialize the automatic slide deployment, the red handle must be pulled for manual deployment. If a ditching line is provided, it has to be fixed to the yellow fittings located in the exit frame and on the wing. 3 L E V E L

EMERGENCY EXIT / OPENING FOR MAINTENANCE NOTE : In this this module the EMERGENCY EMERGENCY EXIT EXIT / OPENING FOR MAINTENANCE is described on the A320 but the principle is the same for the A319. OPENING FOR MAINTENANCE WARNING : MAKE SURE THAT THE LOCKPIN ASSEMBLY ASSEMBLY IS CORRECTLY INSTALLED IN THE OPERATING HEAD OF THE INFLATION RESERVOIR. IT PREVENTS AN ACCIDENTAL EXTENSION OF THE OFFWING ESCAPE SLIDE. To open one of the two emergency exit hatches from the outside, a red panel has to be pushed in, the door falls into the cabin and activates the escape slide release mechanism.

Carefully let the top of the hatch fall inwards so that it comes clear of the structure. Take the lower handle and pull the hatch from the recess. A red manual handle can be used to activate the escape slide release mechanism manually. Install a rigging pin in the provision of the hatch frame. A ditching line attachment point housed in the door frame, and a dual point on the wing upper surface enable the ditching line to be connected.

To open one of the two emergency exit hatches from the inside, pull down the cover flap from the recess. A slide armed indicator comes on to show that the escape slide release mechanism is in the armed configuration. To disarm the mechanism, turn the retractable pin a quarter turn anticlockwise. 3 L E V E L

CAM CAM

The latching shaft, which is connected to the operating handle by an adjustable rod, operates all the hooks. It is the main part of the locking mechanism.

The cam is fastened fastened on the locking shaft and blocks blocks the hooks in the locked position.

LOCKING HOOK In closed and locked position, position, the hooks are in contact with the fuselage slide spools and eccentric eccentric bolts and transmit the loads resulting from the internal pressure. The hooks ensure the locking locking of the cargo door to the fuselage. LOCKING SHAFT When the locking handle is in the LOCKED position, position, the locking shaft turns and the safety cams move into the recess of the locking hooks. The locking shaft is the main part of the safety mechanism. It is actuated by the operating handle.

CARGO DOORS HYDRAULIC SYSTEM DESCRIPTION/OPERATION GENERAL This system controls the operation operation of the FWD and AFT cargo compartment doors. The hydraulic system includes the duplex actuators, two manual selector valves (one for each cargo door), and one electro selector valve. The electrical control system of the cargo doors supplies the hydraulic components with electrical power. It prevents the operation of the system system when the cargo doors are locked. The FWD and the AFT cargo doors can be opened at the same time. The electric pump of the yellow hydraulic system pressurizes the system (3000 psi/207 Hpa).

CARGO DOORS HYDRAULIC SYSTEM DESCRIPTION/OPERATION NORMAL OPENING To open the door in normal conditions, make sure that the door handle is in the UNLOCKED position, out of its recess. On the control panel, near the door, when you begin to turn the selector towards OPEN, an internal switch triggers the electric pump and the electro selector valve. Remain in that position until the green indicator light on the control panel comes on The normal opening procedure is completed. As the selector is set to OPEN, the selector valve moves from the neutral to the extension extension mode to enable pressurization of the actuator chambers.

Then turn the selector, on the control panel, to the "CLOSE" position. Door retraction is made through two successive successive steps. 1 - Interim : The chambers A are pressurized first. In the interim position, the spring loaded blocking piston locks the selector in this position until a sufficient pressure is reached in the extension chambers.

When the hydraulic pressure is high enough, the blocking piston enables the selector to move fully to the "CLOSE" position and to pressurize the retraction retraction chambers of the actuators. The pressure built-up in the retraction chambers closes the internal valve and keeps it closed. The green light goes off. When the manual selector is released, the closing of the internal valve prevents pressurization of extension chambers when the manual selector passes back to the interim position.

The door locking handle must be set to the "UNLOCKED" position. This configuration is an electrical power failure. In case of manual opening, two operators are necessary. While the first operator holds the manual selector valve in the OPEN position, the second operator operates the hand pump on the yellow ground service panel in order to pressurize the A chambers. The operation of the manual selector valve on the control panel, moves the electro electro selector valve to the extension.

DOORS The Centralized Fault Display System (CFDS) SYSTEM REPORT / TEST does not include the DOORS menu page. The purpose of this module is to present the access to the LAST LEG REPORT, the TROUBLE SHOOTING DATA and the TEST of the Landing Gear Control Interface Units (LGCIU) in case of failure of cargo door proximity switches. The cargo door proximity switches monitored by the LGCIUs are :

- Handle proximity switches - Safety mechanism proximity switches - Lockshaft proximity switches. LAST LEG REPORT The handle, safety mechanism and lockshaft proximity switches of the FWD and aft cargo cargo doors send a signal to LGCIU 1 and 2. TROUBLE SHOOTING DATA The following items give a CFDS level 3 information ( engineering maintenance ). When required, the TSM gives the interpretation interpretation of the coded message. 1 L E V E L
