A. Safety Precautions
(1) Make sure that there is sufficient airflow around the aircraft.
(2) Do this task on the apron.

NOTE: We recommend that you move the aircraft away from direct sunlight to easily control the temperature inside the cabin.

(3) If you do this task in the hangar, open the doors of the hangar.
(4) Put SAFETY BARRIER(S) in position to keep all persons out of the work area.
(5) Put WARNING NOTICE(S) in position to tell your personnel about the thermal treatment.

Subtask 12-21-12-869-051-A

C. Get Access

CAUTION: PUT ALL ITEMS WHICH CAN HAVE INSECT INFESTATION AND CAN BE DAMAGED BY TEMPERATURES OF MORE THAN 60 DEG.C (140 DEG.F) IN SEALED PLASTIC BAGS. BEFORE THE THERMAL TREATMENT PROCEDURE STARTS, REMOVE THEM FROM THE AIRCRAFT FOR DISINSECTION. IF YOU DO NOT ISOLATE THESE ITEMS CORRECTLY, INSECTS CAN MOVE TO OTHER ITEMS AND INFESTATION WILL CONTINUE.

(1) Remove the items that follow from the applicable cabin zone:

NOTE: Only equipment that is not sensitive to temperatures of more than 60 DEG.C (140 DEG.F) can stay in the aircraft. Refer to the supplier specification.

(a) Remove all life vests from the aircraft.

NOTE: For life vests in vacuum-sealed plastic bags, no other procedure is necessary. For all other life vests, an individual inspection is necessary.

(b) Remove the escape-slide pack-assembly at the passenger/crew doors, if installed (Ref. AMM TASK 25-62-44-000-002) and (Ref. AMM TASK 25-62-44-000-802).
(c) Remove the escape-slide raft pack-assembly at the passenger/crew doors, if installed (Ref. AMM TASK 25-62-44-000-012) and (Ref. AMM TASK 25-62-44-000-804).
(d) Remove all battery-powered emergency equipment:

The fixed Emergency Locator Transmitters (ELTs), if installed (Ref. AMM TASK 25-65-35-000-001)
The portable ELTs, if installed (Ref. AMM TASK 25-65-32-000-001)
The cockpit and cabin flashlights, if installed
The megaphones.

(e) Remove all portable equipment:

The portable oxygen equipment
The portable breathing equipment
The portable fire extinguishers.

(f) Remove this equipment:

The passenger seats (Ref. AMM TASK 25-21-41-000-001).
The galley equipment. Refer to chapter 2535 to know which galley equipment is installed. Then remove this equipment.
The baby bassinets.

(g) If necessary, remove all items made of fabric such as seat covers, seat cushions, blankets, pillows, mattresses and carpets.

NOTE: We recommend that you do steam cleaning or a different approved high-temperature cleaning procedure. Refer to the manufacturer recommendations.

(2) Open all the window shades and all the internal doors such as the doors of the cockpit, the lavatories, the galley compartments, the stowages, the doghouses and the overhead stowage compartments.

Subtask 12-21-12-869-052-A

D. Aircraft Maintenance Configuration
(1) Install temperature measuring equipment in the applicable cabin area to monitor the temperature and to find possible cold areas.

NOTE: Possible cold areas are the floor, the spaces between seat cushions and the inlet and exhaust of the EXTERNAL HEAT-DISTRIBUTION-SYSTEM.

NOTE: Procurement of the measurement equipment is under the responsibility of the operator.

(2) Close all the passenger/crew doors but keep one door open (Ref. AMM TASK 52-10-00-410-001).

NOTE: A minimum of one door must always stay open. This prevents accidental pressurization of the aircraft and gives access to the inlet and exhaust of the EXTERNAL HEAT-DISTRIBUTION-SYSTEM.

(3) De-energize the ground service network
(Ref. AMM TASK 24-42-00-862-001).

4. Procedure

NOTE: Procurement of the EXTERNAL HEAT-DISTRIBUTION-SYSTEM is under the responsibility of the operator.

(2) Keep the temperature between 52 DEG.C (125.60 DEG.F) and 65 DEG.C (149.00 DEG.F).
