Subtask 27-84-48-941-051-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) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
   (2) Put a WARNING NOTICE(S) in the cockpit to tell persons not to operate the slat controls.
Subtask 27-84-48-860-051-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 flap/slat control lever on panel 114VU.
Subtask 27-84-48-740-052-A
C. Readout of the PPU Data
   (1) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
     (a) 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).
     (b) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).

E. Get Access
   (1) Put an ACCESS PLATFORM 4M (13 FT)-ADJUSTABLE below the applicable torque shaft.
   (2) Remove the applicable torque shaft (1) (Ref. AMM TASK 27-84-45-000-005) and (Ref. AMM TASK 27-84-45-000-007):
     (a) FOR [6013CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6012CM
     (b) FOR [6063CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6062CM.
     (c) FOR [6015CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6016CM.
     (d) FOR [6065CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6066CM.
   (3) Remove the applicable torque shaft (3) (Ref. AMM TASK 27-84-45-000-006):
     (a) FOR [6013CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6014CM.
     (b) FOR [6015CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6014CM.
     (c) FOR [6063CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6064CM.
     (d) FOR [6065CM] (SLAT ACTUATOR TYPE A)
remove the torque shaft FIN 6064CM.
   (4) Make sure that a 98D27504030001 LOCK-TORQUE SHAFT (FLAPS AND SLATS) WITH CLAMP-PIVOT is installed (Ref. AMM TASK 27-50-00-400-003) as follows :
  • On the torque shaft inboard of the removed component
  • On the torque shaft ouboard of the removed component.
4. Procedure
Subtask 27-84-48-020-050-A
A. Removal of the Type A Actuator
   (1) Hold the actuator (2) and remove the bolts (4) and washers (5).
   (2) Remove the actuator (2).
   (3) If you remove the two actuators (2) from the slat, install a 98D27804006000 TOOL-ALIGNMENT AND LOCKING (SLAT TRACKS 2 AND 3) in each pinion after each actuator (2) is removed. This will prevent movement of the slat.
