De-Icing of the Aircraft after a Landing with Snow on the Runway

TASK 12-31-12-660-007-A
De-Icing of the Aircraft after a Landing with Snow on the Runway

WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
WARNING: LET THE BRAKES AND THE WHEELS BECOME COOL BEFORE YOU GO NEAR THE LANDING GEAR. DO NOT APPLY A LIQUID OR GAS DIRECTLY ON A HOT WHEEL OR BRAKE UNIT. THIS CAN CAUSE A TIRE EXPLOSION AND/OR A WHEEL RIM BURST.
CAUTION: DO NOT TRY TO OPERATE THE FLIGHT CONTROL SURFACES IF THERE IS ICE ON THEM. IF YOU DO, YOU CAN CAUSE DAMAGE TO THE SYSTEM. SMALL SURFACE MOVEMENT IS PERMITTED AT HYDRAULIC POWER-UP OF AIRCRAFT.
CAUTION: DO NOT USE JET EXHAUST TO REMOVE SNOW OR ICE FROM THE AIRFRAME. THE HIGH PRESSURE AND HIGH TEMPERATURE OF JET EXHAUST CAN CAUSE DAMAGE TO THE AIRCRAFT.
CAUTION: DO NOT USE HIGH-PRESSURE JETS OR VAPOR TO DO THE ANTI-ICING/ DE-ICING PROCEDURE. THIS TYPE OF EQUIPMENT CAN PUT FLUID IN PARTS, AND CAN CAUSE DAMAGE TO EQUIPMENT, SPECIALLY TO:
  • ELECTRICAL EQUIPMENT SUCH AS HARNESSES, PROXIMITY SENSORS AND CONNECTORS (WITH SHORT CIRCUITS OR INCORRECT INDICATIONS AS A RESULT)
  • EQUIPMENT SUCH AS GEAR BOX SEALS, STEADY BEARINGS, ROTARY ACTUATORS AND UNIVERSAL JOINTS.
HIGH PRESSURE JETS CAN PUSH LIQUIDS INTO BEARINGS, JOINTS, BRAKES, ELECTRICAL CONNECTORS AND OTHER SEALED COMPONENTS. LIQUIDS THAT GET INTO THESE AREAS CAN CAUSE CORROSION, FREEZE DURING AIRCRAFT FLIGHT, REMOVE NECESSARY LUBRICANTS OR START INCORRECT ELECTRICAL FUNCTIONS.
1. Reason for the Job
This procedure gives guidelines for the removal of snow and ice from some areas of the aircraft.
NOTE: The source of all the data related to the fluids must be the manufacturer's recommendations for application and holdover times (supplied with the fluid). The ice protection procedures and all the data related to de-icing/anti-icing fluids are given in the SAE standards available on the website www.sae.org:
  • SAE AS 6285 (Aircraft Ground De-Icing/Anti-Icing Processes).
  • SAE AS 6286 (Training and Qualification Program for De-Icing/Anti-Icing of Aircraft on the Ground).
NOTE: The operators must use the procedures applicable to their special operating procedures and requirements.
NOTE: The data given in this procedure are guidelines only.
These guidelines and their experience and knowledge of the local weather conditions help the operators to make correct decisions.
It is the responsibility of the operators to make the decision about the applicable protection procedures.

3. Job Set-up
Subtask 12-31-12-660-079-A
A. De-Icing General Information
   (1) Refer to (Ref. AMM TASK 12-31-00-600-001) for:
  • The definition
  • The cold weather procedures
  • The de-icing and anti-icing guidelines
  • The materials that you can use
  • The general information on effects of icing
  • The de-icing and/or anti-icing equipment and materials.
Subtask 12-31-12-941-060-A
B. Safety Precautions
   (1) Put the wheel chocks in position (Ref. AMM TASK 10-11-00-555-015).
   (2) Install the safety devices on the landing gear (Ref. AMM TASK 32-00-00-481-001).
   (3) Make sure that the engines are stopped.
4. Procedure
Subtask 12-31-12-660-066-A
A. Removal of Snow and Ice from the Aircraft
   (1) Remove all signs of snow and ice from:
  • The wing leading edges
  • The flap and slat mechanisms
  • The flap and slat tracks
  • The rear spar area of the wing (above and in front of the flaps).
To do this, use:
   (2) Remove all signs of snow and ice from:
  • The landing gears (the wheels and the brake system)
  • The engine air intakes and the fan duct
  • The engine fan blades (this includes the rear side of the engine fan blades).
To do this, use:
  • A BRUSH - BRISTLED, SOFT or
  • A BROOM with soft bristles or
  • Hot water.

It is permitted to use forced air for the de-icing of the flaps/slats and mechanisms after a landing on a runway with contamination. The procedure and equipment must agree with SAE AIR6284.
Airbus does not recommend to use forced air mixed with de-icing fluid.
If the procedure to use forced air mixed with de-icing fluid is the only available procedure:
  • Decrease the fluid to the lowest possible pressure.
  • Do not spray fluid on the flap/slat actuator mechanisms.

For the flaps and flap track fairings, use only Type I de-icing fluid.
NOTE: De-icing fluid thickeners of Type II, III or IV will cause residue or gel.
When you use de-icing fluid, make an entry in the aircraft logbook. This is to tell persons to clean the flap/slat mechanisms immediately.
Subtask 12-31-12-210-058-A
B. If you think that snow will fall, put the aircraft in this configuration
   (1) Install the aircraft protection equipment (Ref. AMM TASK 10-11-00-555-013).
   (2) Make sure that you close all:
  • Access doors and panels,
  • Landing gear doors,
  • Passenger/crew doors and exits,
  • Cargo compartment doors,
  • Sliding windows.
   (3) Make sure that the flaps, slats, spoilers, speedbrakes and thrust reverser doors are retracted.
   (4) Make sure that the trimmable horizontal stabilizer is in the neutral position.
5. Close-up
