R NOTE : Airbus recommends that the park brake is set to ON when
____
R possible. You cannot set the PARK BRK to ON if you have hot
R brakes. If you cannot set the PARK BRK to ON, it is possible
R to continue but you must make sure the chocks are in the
R correct position.
R (10) Make sure that the chocks are in position. The correct position for
R the chocks are:
R (a) If the ramp is flat (no slope):
R - move the aft chocks away from the tires. During the refuel,the
R NLG tires will roll aft as the MLG shock absorber compresses
- make sure that the chocks do not touch the MLG tires. The
R weight of the fuel can lower the aircraft and cause the chocks
R to be caught under the tires.
R (b) If the ramp has a slope:
R - make sure that the chocks down from the tires touch the NLG and
R MLG tires
R - make sure that the chocks up from the tires do not touch the
R NLG and MLG tires.
R
R NOTE : This makes sure that only chocks on one side of each tire
____
R will be caught so that it is easier to release them.
(11) Make sure that there is no equipment below the aircraft which can
cause damage. The weight of the fuel can suddenly compress the
landing gear and lower the aircraft.

NOTE : The degree of cleanliness of the hydraulic fluid used for
____
replenishing (topping up of the hydraulic systems and
hydraulic cart reservoirs) must agree with class 7 of the NAS
specification 1638 (initial state).
C. Hydraulic Ground Power Cart
Only hydraulic ground power carts with a hydraulic reservoir must be
used.
The fluid sampling operation for contamination of the hydraulic fluid
must be monitored and the sample analysis record kept on file.
D. Hydraulic Fluid Property In-Service limits.
The hydraulic fluid property in-service limits are:
- The physical properties,
- The chemical properties.
(Ref. Fig. 002)
NOTE : The maximum water contents permitted by the manufacture in
____
hydraulic fluids is 0.8 %. But this limit together with very high
temperatures decreases the life of the hydraulic fluids. Airbus
Industrie thus recommends to decrease the limit to 0.5 % which
will increase the life of the hydraulic fluid.
(1) The quality of the hydraulic fluid must be in the limits given in
Fig. 002.
(a) If the water or chlorine content of the hydraulic fluid are equal
or more than the permitted values:
Clean it with the HYDRAULIC PURIFIER (HSPA181-380J):
- (Ref: 12-36-29-615-001)
- (Ref: 12-36-29-615-002)
- (Ref: 12-36-29-615-003)
Or change the hydraulic fluid:
- (Ref: 12-36-29-600-001)
- (Ref: 12-36-29-600-002)
- (Ref: 12-36-29-600-003)
(b) If the acidity, density or viscosity of the hydraulic fluid are
more than the permitted values:
Change the hydraulic fluid:
- (Ref: 12-36-29-600-001)
- (Ref: 12-36-29-600-002)

LUBRICATION - DESCRIPTION AND OPERATION
_______________________________________
1. _______
General
The lubrication instructions define:
- the specification of the lubricant to be used
- the points to be lubricated
- the special precautions to be observed.
A. Equipment and Materials
Depending on the type of lubrication, you can use:
- a grease gun
- an oil can
- a brush
- a clean lint-free cloth
- an aerosol spray.
B. Lubricant Grease Specifications
(1) The references of lubricants and greases are given in the list of
materials required for aircraft servicing and maintenance (Ref. ATA
20-31).
(2) Airbus recommendations related to the mixing of greases
(a) Do not mix greases that have different specifications.
NOTE : Refer to SIL12-008 for more information on mixing of
____
greases.
(b) After selection of a grease specification, always use a grease
that has the same specification.
(c) If it was necessary to mix greases that have different
specifications (specially greases with clay thickeners and
greases with lithium thickeners), decrease the MPD service
intervals by half for approximately 3 or 4 services.
NOTE : This will give a better purge in the related mechanism.
____
(d) For a satisfactory purge in the mechanism, continue to put the
new grease into the grease fitting while the old grease comes
out. Stop when you see only the new grease come out.

(2) Before you start a lubrication operation, carefully clean the grease
nipples lubricating-holes.
You must do the lubrication immediately.
Make sure that the grease nipples have balls and springs.
(3) Make sure that the old grease comes out of the pressure relief valves
and on each side of the spherical bearings (unless there is an
indication of the quantity of grease to be used).
(4) After lubrication, remove all unwanted grease. Wipe the grease nipple
with a clean, lint-free cloth.
Make sure that the balls and springs are in position.

USE OF MANUAL (MAGNETIC) FUEL QUANTITY INDICATORS - DESCRIPTION AND OPERATION
_____________________________________________________________________________
1. _______
General
Manual Magnetic Indicators (MMIs) can be used to find the quantity of fuel
in the tanks when the aircraft is on the ground. Electrical power is not
required to operate the MMIs.
Before the MMIs are used it is necessary to find the aircraft attitude
value.
To find the quantity of fuel in the tanks it is necessary to use conversion
tables and this data:
- the MMI readings
- the aircraft attitude value
- the specific gravity of the fuel.
The MMIs each contain a Magnetic Level Indicator (MLI) and its related
Magnetic Level Indicator Housing (MLIH), these are fully described in (Ref.
28-43-00) and for their use (Ref.12-11-28).

AIRCRAFT PROTECTION - DESCRIPTION AND OPERATION
_______________________________________________
1. _______
General
Safe operation of aircraft in cold weather conditions raises specific
problems. Aircraft downtime and delays in flight schedules caused by cold
weather problems can be minimized by a program of preventive cold weather
servicing.
Procedures for cold weather servicing during cold weather must be developed
by the operator. This servicing must meet their specific requirements based
on :
- their cold weather experience

C. De-icing and Anti-icing Guidelines
R CAUTION : DO NOT MAKE THE ANTI-ICING/DE-ICING FLUID IN TANKS HOT TOO MANY
_______
R TIMES OR FOR LONG PERIODS. IF YOU DO, THE QUANTITY OF WATER IN
R THE FLUID WILL DECREASE AND THERE WILL BE A POSSIBLE
R DEGRADATION OF THE FLUID PERFORMANCE.
(1) De-Icing and Anti-Icing Glossary
(a) De-icing is a procedure to remove frost, ice, snow and slush from
the aircraft surfaces.
(b) De-icing fluids are usually applied heated. Typical de-icing
fluids are:
- Heated water,
- Newtonian fluids (ISO or SAE or AEA Type I ANTI-ICING AND DE-
ICING MATERIALS (Material No. 10-001)),
- Mixtures of water and Type I fluid ANTI-ICING AND DE-ICING
MATERIALS (Material No. 10-001),
- Non-Newtonian fluids (ISO or SAE or AEA Type II ANTI-ICING AND
DE-ICING MATERIALS (Material No. 10-003) or Type IV ANTI-ICING
AND DE-ICING MATERIALS (Material No. 10-004)),
- Mixtures of water and Type II ANTI-ICING AND DE-ICING MATERIALS
(Material No. 10-003) or Type III ANTI-ICING AND DE-ICING
MATERIALS (Material No. 10-005) or Type IV ANTI-ICING AND DE-
ICING MATERIALS (Material No. 10-004) fluids.
(2) Follow the fluid manufacturers guidelines to increase the
temperature of de-icing and anti-icing fluids.
De-icing and anti-icing fluids are not heated in tanks too many times
or for long periods because:
- The quantity of water in the fluids will decrease and
- There will be a possible degradation of the fluid performance.
.For Type I fluids ANTI-ICING AND DE-ICING MATERIALS (Material No.
10-001), water loss can cause unwanted aerodynamic effects.
.For Type II ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-
003) and Type IV ANTI-ICING AND DE-ICING MATERIALS (Material No.
10-004) fluids, thermal exposure and/or water loss can decrease
fluid viscosity which causes shorter holdover times.
One or more of the conditions that follow can decrease fluid
performance:
- Not much fluid used
- Trucks that do not operate with heating system on for long periods
of time
- High temperatures in fluid tanks,
- High temperatures in water tanks which directly touch the fluid
tanks (no insulation between tanks).

R (3) Anti-icing is a procedure wich gives protection from the formation of
R frost or ice and snow accumulations on the treated surfaces of the
R aircraft for a limited period of time (the holdover time).
R (4) Anti-icing fluids are usually applied cold directly onto a clean
R aircraft surface.
Typical anti-icing fluids are:
- Newtonian fluids (ISO or SAE or AEA type I ANTI-ICING AND DE-ICING
MATERIALS (Material No. 10-001)),
- Mixtures of water and Type I fluid ANTI-ICING AND DE-ICING
MATERIALS (Material No. 10-001),
- Non-Newtonian fluids (ISO or SAE or AEA Type II ANTI-ICING AND DE-
ICING MATERIALS (Material No. 10-003) or Type III ANTI-ICING AND
DE-ICING MATERIALS (Material No. 10-005) or Type IV ANTI-ICING AND
DE-ICING MATERIALS (Material No. 10-004)).
- Mixtures of water and Type II ANTI-ICING AND DE-ICING MATERIALS
(Material No. 10-003) or Type III ANTI-ICING AND DE-ICING MATERIALS
(Material No. 10-005) or Type IV ANTI-ICING AND DE-ICING MATERIALS
(Material No. 10-004) fluids.
R (5) Non-Newtonian fluids (Type II or Type III or Type IV) have a
R viscosity that decreases when the air flow over the fluid increases.
R (6) Newtonian fluids (Type I) have a low viscosity that only changes with
temperature.
(7) Holdover time is the estimated time during which anti-icing fluids
R will prevent the formation of frost or ice and snow accumulations on
R the treated surfaces of the aircraft. The holdover time starts at the
beginning of the anti-icing treatment.
R (8) De-icing/anti-icing is a combination of the de-icing and the
R anti-icing procedures and it is possible to do these procedures in
R one or two steps.
R (9) One-step de-icing/anti-icing uses an anti-icing fluid, usually
R heated. The fluid removes the ice from the aircraft and then stays on
R the aircraft and gives limited anti-ice protection.
R (10) Two-step de-icing/anti-icing has two fully separate steps :
R First, do the de-icing of the aircraft (remove frost, ice, slush and
R snow accumulations).
R Then, immediately do an anti-icing procedure.
R NOTE : Two step de-icing/anti-icing is the Airbus and EASA-preferred
____
R method because one-step de-icing, with Type II, III or IV,
R only causes build up of residues in the aircraft.

R After long periods of de-icing/anti-icing, it is recommended
R to do a check of areas and cavities that are not in the
R aerodynamic airflows (such as balance bays and wing and
R stabilizer rear spars) for thickened fluid residues.
Subtask 12-31-00-860-053
D. General Information on Effects of Icing
R (1) Aircraft performance certification is based on the performance of the
R aircraft with an uncontaminated or clean structure.
R (2) Ice, snow and frost or combinations of these will change the airflow,
R and have an effect on lift and drag. They also increase the aircraft
R weight.
R (3) The aircraft, and especially its surfaces that give lift and
R stability, must be aerodynamically clean. If they are not, safe
operation is not possible.
R (4) If the fuel temperature is lower than freezing point and the aircraft
R is in precipitation, clear ice can form on the wings (wing tank
R area), even if the outside temperature is as high as 15 deg.C (59.00
deg.F).
R (5) An aircraft that is ready for flight must not have ice, snow, slush
R or frost on its critical flight surfaces (Wings, vertical and
R horizontal stabilizers and rudder).
Thin hoarfrost is permitted on the upper surface of the fuselage.
NOTE : Thin hoarfrost is usually a white crystalline deposit which
____
R usually develops equally on external surfaces on cold nights
R without clouds. It is sufficiently thin that you can see
R surface features (lines or markings) below it.
R NOTE : A frost layer of less than 3 mm (0.1181 in.) on the wing lower
____
R surface (in the area of fuel tanks) is permitted without
R effect on take-off performance if it is caused by cold fuel
R (low fuel temperature, OAT higher than freezing point and high
R humidity).
R This is not applicable to THS.
EFF :
ALL 12-31-00

UZB
(6) A contamination check of the aircraft must include all parts of the
aircraft. You must do this visual inspection from a position which
R gives a clear view of all surfaces. Because you cannot always see
R collected clear ice easily, we recommend that you do an inspection of
R the critical surfaces (wings, vertical and horizontal stabilizers and
R rudder) with your hands.
R (7) Weather conditions determine when de-icing/anti-icing of the aircraft
R is necessary.
(8) During checks on the ground, electrical or mechanical ice-detectors
must not replace physical checks.
(9) If the aircraft arrives at the gate with the flaps/slats in a
R position other than fully retracted, you must do an inspection of
R these flaps/slats, and de-ice them before retraction if necesary.
Subtask 12-31-00-860-054
E. De-icing and/or Anti-icing Equipment and Materials
(1) Type I Fluids
R Type I fluids ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-001)
R are usually used for aircraft de-icing and have only a limited effect
R when used for anti-icing.
R Type I fluids have a minimum of 80 % by volume of either:
- Monoethylene-glycol
- Diethylene-glycol
- Monopropylene-glycol
- or a mixture of these glycols.
R The other 20% are:inhibitors to restrict corrosion and increase the
R flash-point
R - Inhibitors, to inhibit corrosion and increase the flash-point.
R
R - water and wetting agents.
R These fluids have a low viscosity which only changes with
R temperature.
R The freezing point of a water/glycol mixture will change with the
R quantity of water contained in the fluid. The lowest freezing point
R of concentrated Type I fluid will be approximately -10 deg.C
R (+14.00 deg.F). A 60/40 Type I fluid-to-water mixture ( freezing
R point below -50 deg.C (-58.00 deg.F)) will give protection for
R lowest temperatures. But because of its lower viscosity, it will
R flow off the wing more easily. Therefore, a 50/50 Type I
R fluid-to-water mixture is usually used.

UZB
R (2) Type II ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-003), or
R Type III ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-005), or
R Type IV ANTI-ICING AND DE-ICING MATERIALS (Material No. 10-004)
R fluids have a minimum of 50% by volume of either:
- Monoethylene-glycol
- Diethylene-glycol
- Monopropylene-glycol
- or a mixture of these glycols.
R The other 50% is:
R - Inhibitors,to prevent corrosion and increase the flash-point
R - Water and wetting agents,to help the fluid form a uniform film over
R the aircraft surfaces
R - Thickening agents, to help the fluid to adhere to the aircraft
R surfaces for longer periods.
R The holdover time is longer for Type II or Type III or Type IV
R fluids than for Type I fluids.
(3) Holdover times
Holdover times are the estimated times that the applied anti-icing
R fluid will prevent the formation of frost, ice and the accumulation
R of snow on the treated surfaces of an aircraft.
R When you do a one-step de-icing/anti-icing procedure (not recommended
R by Airbus), the holdover time starts when you apply the fluid.
R When you apply the first step of a two-step de-icing/anti-icing
R procedure, the holdover time starts when you apply the fluid.
R The holdover times given are for general information only. Conditions
R can make the protection times shorter:
R - severe weather
R - strong winds and jet blasts
R - the age and condition of the fluid
R - the method used to apply the fluid.
(4) Equipment
(a) Mobile equipment
R Truck-mounted de-icing/anti-icing equipment must usually be
R compatible for the application of Type I, Type II, Type III and
Type IV fluids.
R De-icing and anti-icing fluids can show degradation (for example
R viscosity decreased) because of too much mechanical shearing.
R Therefore, you must only use compatible pumps and spraying
R nozzles recommended by fluid manufacturers.
To be compatible with AEA guidelines, centrifugal pumps can be
used with Type I fluids.

(b) Static facilities
Purpose-built de-icing/anti-icing facilities, available at some
R airports, consist of spray nozzles installed on a gantry. The
R gantry moves at a given speed above the aircraft or the aircraft
R moves below the gantry. The rate of fluid application can be
R computer-controlled to give regular and fast fluid application.
(c) Protective clothing
R When you use de-icing/anti-icing fluids, you must use the usual
R precautions related to chemicals. You must put on protective
R clothing, protective glasses and apply an approved cream on the
R exposed skin.

(1) Remove any ice from :
- the wing leading edge
- the slats
- the flaps
- the spoilers
- the ailerons
(2) You must retract the wing flaps and slats during periods of snowfall
and icing conditions. If it is necessary to operate these controls,
make sure that they are clear of accumulation before retraction.
(3) If an aircraft arrives with the slats and flaps in a positon other
than fully retracted during a period of ice or snow conditons, those
slats and flaps which are extended must be inspected for ice and snow
accumulation before retracting.
(4) All control surfaces must have no ice, snow or frost. After the
deicing operation, do a check of the associated hinges, tracks,
actuators and servo controls for trapped moisture that can freeze.

(2) The winter preparation program should include the flap and slat
lubrication.
NOTE : In climates where the atmosphere is both particularly cold and
____
humid (mist/fog) use your experience to reduce the lubrication
task intervals during winter operations.
NOTE : In extreme climates and low ambient temperatures it may be
____
difficult to lubricate the flap and slat systems correctly. If
hangar space is not available then it is recommended to do the
lubrication tasks at a station where the approppriate
facilities are available or where the ambient temperature is
above 0 deg.C (32.00 deg.F).
NOTE : Increases in grease stiffness may occur if water present
____
within a lubricant forms discrete lumps of ice, the associated
increases in system friction may then result in torque limiter
operation.
(3) When you do the lubrication tasks take care to ensure that all the
old grease is removed in order to reduce the risk of an increase in
grease stiffness.

Job Set-up
Subtask 12-31-28-869-050
A. General Information
This procedure gives the cold weather maintenance practices for the fuel
system when:
- an aircraft is operated or stored in conditions with ground
temperatures of between 0 deg.C (32 deg.F) and -54 deg.C (-67 deg.F)
or
- the fuel temperature in the tanks is less than -5 deg.C (23 deg.F).
The fuel storage and handling conditions can have an important effect on
the amount of water in solution with the fuel. In unsatisfactory
conditions, each 3785 liters (1000 USgal) of fuel can contain up to 0.76
l (0.2 USgal) of water. Water can get into the tanks in different ways:
- the fuel supplied to the aircraft contains water
- the air in the tank contains moisture (water)
- during descent large quantities of moist air can enter the tank
- fuel which is open to dampness or wet atmospheric conditions will
contain larger quantities of water than fuel stored in sealed
containers.
In cold conditions, much of this water can come out of solution and fall
to the bottom of the tank. It then collects at the lowest parts of the
tank and can form ice. The formation of ice (and the presence of water)
in the fuel tanks can have an effect on the accuracy and/or performance
of the quantity indication system. It can also cause engine or corrosion
related problems.
Approved anti-ice additive can be added, in the correct proportions, to
the fuel which is supplied to the aircraft. This can prevent water in the
fuel from freezing and let it be drained from a tank with a fuel
temperature below 0 deg.C (32 deg.F). The ice in the fuel tank can be
melted through these procedures:
- ambient air heat in a hangar
- a refuel with warm fuel
- warm air heat from a blower, until the temperature of the whole of the
bottom skin is 1 deg.C (34 deg.F). This procedure is usually done in a
hangar, but can be used outside if a hangar is not available
- a combination of these methods.
NOTE : Ice can form on the inside of the fuel tank close to the water
____
drain valve. When you drain fuel from the tank for a water
analysis check, fuel flows over the ice and collects water. This
EFF :
ALL 12-31-28

can cause incorrect analysis results. The procedure that follows
should remove most of the water/ice from the fuel tank.
You must do the water drain procedure regularly to make sure that
all the water is drained from the tank low points.

B. Safety Precautions
WARNING : OBEY THE FUEL SAFETY PROCEDURES.
_______
(1) You must obey the fuel safety procedures (Ref. TASK 28-00-00-910-001)
when you do work on the fuel system.
R (2) Put the SAFETY BARRIER(S)S in position.

A. Water Draining of the Tanks
(1) If a water drain does not open with the usual pressure, find the
cause. The valve could be frozen because of the low temperature.
(2) Water draining of the tanks (aircraft in a hangar):
(a) If possible, refuel the aircraft with warm fuel.
(b) Use a surface contact thermometer to measure the temperature of
the bottom skin of the tank to be drained.
(c) If necessary, use an approved hot air blower to warm the bottom
skin of the tank to be drained. Make sure the temperature of the
bottom skin does not increase to more than 50 deg.C (122.00
deg.F).
NOTE : The temperature of all the bottom skin should be 1 deg.C
____
(33.80 deg.F) or more measured one minute after the
removal of the hot air blower.
(d) Drain accumulated water (Ref. TASK 12-32-28-281-001) 30 minutes
after the aircraft has been refuelled (and before the bottom skin
temperature decreases below 0 deg.C (32.00 deg.F)).

(3) Water draining of the tanks (aircraft outside):
CAUTION : MAKE SURE THAT THE TEMPERATURE OF THE AIR FROM THE HOT AIR
_______
BLOWER IS NOT MORE THAN 50 DEG.C (122 DEG.F).
IF THE TEMPERATURE IS MORE THAN 50 DEG.C (122 DEG.F) YOU
CAN CAUSE DAMAGE TO THE AIRCRAFT.
(a) If possible, refuel the aircraft with warm fuel.
(b) Use a surface contact thermometer to measure the temperature of
the bottom skin of the tank to be drained.
NOTE : To do the procedure the temperature near to the drain
____
valves should be 1 deg.C (33.80 deg.F) or more. It is
possible that not all of the ice will be melted, thus the
drain procedure will not be fully successful.
(c) Use an approved hot air blower to warm the bottom skin of the
tank to be drained. Make sure the temperature of the bottom skin
does not increase to more than 50 deg.C (122.00 deg.F).
NOTE : The temperature of the bottom skin near to the drain valve
____
should be 1 deg.C (33.80 deg.F) or more measured one
minute after the removal of the hot air blower.
(d) Drain the accumulated water (Ref. TASK 12-32-28-281-001) 30
minutes after the aircraft has been refuelled (and before the
bottom skin temperature near to the drain valves decreases below
0 deg.C (32.00 deg.F)).

A. General
(1) When the ambient temperature decreases, the pressure in the tires
also decreases.
A 3 deg.C (5.4 deg.F) change in temperature causes a 1% change in
tire pressure.
NOTE : The tires wear faster if the pressure in the tires is low.

Subtask 12-31-32-660-051
B. Recommendations
(1) Check the tire pressure
If the aircraft is parked in cold weather conditions (cold soak) for
more than one hour, do a check of the tire pressure.
If necessary, correct the pressure with nitrogen (Ref. TASK 12-14-32-
614-001).
NOTE : Do not use air to correct the tire pressure. If the ambient
____
temperature is below 0 deg.C (32.00 deg.F), moisture in the
air can change to ice in the valve and cause a permanent leak.
(2) Remove ice and/or snow from the landing gear
NOTE : De-ice the landing gear no more than 1 hour before flight.

(2) Ice can collect in the lower fuselage areas especially when the
aircraft flies from warm, humid climates to cold climates. In some
conditions, the ice can collect during more than one flight.
NOTE : Water/ice in the lower fuselage can cause failure of the radio
____
altimeter.
(3) When you do a check for ice in the lower fuselage, look for ice in
the aft area before you look in the forward area. Ice usually
collects more easily in the aft area than in the forward area. Water
evaporation is faster in the forward area because of the warm air
from the avionics compartment.
Subtask 12-31-51-660-051
B. Check for Ice
(1) Remove a floor panel from the forward end of the aft cargo
compartment. (Ref. TASK 53-42-14-000-001)
(2) Look for ice in the lower fuselage.
(3) If you find ice below the aft cargo compartment, look for ice below
the forward cargo compartment.
(4) Install the floor panel (Ref. TASK 53-42-14-400-001).
(5) Frequency of check
You must adapt the frequency of the check to the climatic conditions
in which the aircraft operates. In the worst condition one check per
week should be sufficient initially.
