Subtask 27-50-00-941-063-A
A. Safety Precautions
   (1) As necessary, use the applicable SAFETY BARRIERS, specified by the operator's instructions and your local regulations.
   (2) Put the WARNING NOTICE(S) in position to tell persons that the flap and slat systems are in operation.
Subtask 27-50-00-860-065-A
B. Aircraft Maintenance Configuration
WARNING: OBEY THE HYDRAULIC SAFETY PROCEDURES.
   (1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
   (2) If applicable, disconnect the Power Transfer Unit (PTU) (Ref. AMM TASK 29-23-00-860-001).
NOTE: The flaps move at full-speed if the Power Transfer Unit (PTU) is in operation. If the PTU is disconnected (electrically or hydraulically), only the yellow flap motor operates and the flaps move at half-speed.

NOTE: An ECAM F/CTL FLAP SYS 1 FAULT message will show when the PTU is isolated. This message can be ignored.
   (3) Pressurize the Yellow hydraulic system (Ref. AMM TASK 29-10-00-863-002).
   (4) Pressurize the Blue hydraulic system (Ref. AMM TASK 29-10-00-863-003).
NOTE: The Blue and/or Green hydraulic system(s) operate(s) the slat system. If necessary, use the alternative hydraulic system.

4. Procedure
Subtask 27-50-00-866-061-A ** ON A/C NOT FOR ALL
A. Extension of the Flaps/Slats on the Ground
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.
CAUTION: IF THE THRUST REVERSER COWLS ARE OPEN, MAKE SURE THAT THE HALF DOORS OF THE THRUST REVERSER ARE CLOSED BEFORE YOU EXTEND THE SLATS. IF THE DOORS ARE OPEN, YOU CAN CAUSE DAMAGE TO THE SLATS AND HALF DOORS WHEN THE SLATS EXTEND.
   (1) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
   (2) Set the flap/slat control lever to the applicable position 1, 2, 3 or FULL.
   (3) Make sure that on the ECAM upper DU:
  • the flap position bar moves to the set position
  • the slat position bar moves to the set position.
   (4) Install the 98D27803000000 LOCKING TOOL-FLAP SLAT LEVER,INT. POSITION on the flap/slat control lever (Ref. AMM TASK 27-00-00-480-002).
