Subtask 27-84-49-941-052-A

A. Safety Precautions

WARNING: BEFORE YOU START WORK, YOU MUST PUT ON A SAFETY HARNESS AND ATTACH IT TO THE ACCESS PLATFORM. WITHOUT A SAFETY HARNESS, YOU CAN FALL. THIS CAN KILL YOU OR CAUSE YOU INJURY.

(1) Put the SAFETY BARRIER(S) in position.
(2) Put WARNING NOTICE(S) in the cockpit to tell persons not to operate the slat controls.

Subtask 27-84-49-860-050-A

B. Aircraft Maintenance Configuration

WARNING: MAKE SURE THAT THE TRAVEL RANGES OF THE FLIGHT CONTROLS SURFACES ARE CLEAR. MOVEMENT OF FLIGHT CONTROLS CAN CAUSE INJURY TO PERSONS AND/OR DAMAGE TO EQUIPMENT.

(1) Retract the slats fully (Ref. AMM TASK 27-80-00-866-005).
(2) Install the 98D27803500001 LOCKING TOOL ZERO POS or 98D27803500002 LOCKING TOOL ZERO POS on the slat/flap control lever, on panel 114VU.

Subtask 27-84-49-740-055-A

C. Readout of the PPU Data
(1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
(2) Do the readout of the PPU data (Ref. AMM TASK 27-80-00-860-801).

NOTE: Airbus recommends to do the readout and recording of the PPU angles before the maintenance action.
In case of a loss of the torque shaft fixture you can put the slat transmission system back to the initial condition (without a complete adjustment of the system).

(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).

4. Procedure
Subtask 27-84-49-020-050-A

A. Removal of the Type B Actuators
(1) Hold the actuator (7) and remove the bolts (9) and washers (8).
(2) Remove the actuator (7).
(3) If you remove both actuators from a slat, install a 98D27804007000 TOOL-ALIGNMENT AND LOCKING (SLAT TRACKS 5 TO 12) in each pinion, after each actuator (7) is removed or the slat will extend.
