TASK 12-32-28-281-001-ADrain Water Content

WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOUSTART A TASK ON OR NEAR:- THE FLIGHT CONTROLS- THE FLIGHT CONTROL SURFACES- THE LANDING GEAR AND THE RELATED DOORS- COMPONENTS THAT MOVE.MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/ORCAN CAUSE DAMAGE TO THE EQUIPMENT.

1. Reason for the JobRefer to the MPD TASK: 281100-01DRAIN WATER CONTENT

NOTE: This task can be done together with TASK 12-32-28-281-003-A (Sample Fuel forMicrobiological Contamination Analysis) and TASK 12-32-28-281-80200 (Sample Fuelfor Hydraulic-Oil Contamination Analysis). If you do the Microbiological/Hydraulic-OilContamination Analysis, the applicable drain tool and the container must be cleaned as given inthe AMM tasks.

NOTE: If possible, do the water drain procedure before the flight or the refuel procedure. If you do thisprocedure after the flight or the refuel procedure, you must:- Wait for one hour for the separation of the water and the fuel.

NOTE: It is permitted to do this procedure when the APU is in operation only if the fuel tank pumps areset to OFF.

NOTE: For the gravity procedure AIRBUS recommends that there must be more than 10% content offuel in each tank. If you have less than 10% content of fuel, then the indirect water drain valveswill have a decreased flow. It is recommended that you use the suction procedure when youhave less than 10% content of fuel.

Subtask 12-32-28-941-054-BA. Safety Precautions

WARNING: OBEY THE FUEL SAFETY PROCEDURES.

(1) You must obey the fuel safety procedures when you do work on the fuel system (Ref. AMM TASK 28-00-00-910-001) .

(2) Put the safety barriers in position.(3) Make sure that the ground safety locks are installed on the landing gear

(Ref. AMM TASK 32-00-00-481-001) .(4) On the panel 400VU:

Make sure that the landing-gear control-lever 6GA is in the DOWN position Put a warning notice in position to tell persons not to operate the landing gear.

(5) Put a WARNING NOTICE(S) in position to tell persons not to operate the landing gear doors.(6) If the fuel temperature is less than 0 DEG.C (32.00 DEG.F) and/or the water drain valves are

frozen, to keep the flight turnaround times, either: Do the cold weather maintenance procedure to warm the water drain valve

(Ref. AMM TASK 12-31-28-660-001) or

Remove the fuel samples 30 minutes after the refuel procedure.

NOTE: Removal of the fuel samples after 30 minutes will not remove the water content assatisfactorily as samples removed one hour after the refuel procedure.

NOTE: Do not apply unusually high force to open the water drain valve.

(7) If the APU is in operation during this procedure, you must make sure the fuel tank pumps areset to OFF.

Subtask 12-32-28-010-050-BB. Get Access

(1) For access to the center tank water drain valves, open the applicable access panels: For water drain valve 94QM, open access panel 195BB For water drain valve 95QM, open access panel 196BB.

Subtask 12-32-28-480-050-AC. Preparation of the Equipment

(1) To get access to the high water drain valves from the ground, attach the: ADAPTING PIPE - WATER DRAINING FROM FUEL (98A28101000000)

or the PIPE ADAPTING-WATER DRAINING (98D28104000000)

to the bottle and funnel of the PURGER - WATERDRAIN (98A28104000000) .

** ON A/C ALLSubtask 12-32-28-281-050-BA. Fuel Sampling for Water Contamination

(1) Gravity ProcedureNOTE: Make sure that the fuel tanks are filled to a minimum of 10% of capacity. This is

necessary to cover the water drain valve outlet, so that the water drain valves canoperate satisfactorily. Refer to SIL for data SIL 28-079.

(a) For the wing-tank water drain valves:CAUTION: MAKE SURE THAT THE PLUNGER OF THE TOOL ALIGNS CORRECTLY

WITH THE WATER DRAIN VALVE. INCORRECT ALIGNMENT OF THETOOL CAN CAUSE:- THE WATER DRAIN VALVE TO STAY IN THE OPEN POSITION AFTER

THE TOOL IS REMOVED- A FUEL LEAK.

1 Push the center of the applicable water drain valve with the PURGER - WATERDRAIN (98A28104000000) . Drain approximately 1.0 l (0.26 USgal) of fuel from thewater drain valve.

NOTE: A rubber shield prevents fuel leakage.

2 Remove the PURGER - WATER DRAIN (98A28104000000) from the water drainvalve.

3 Examine the water drain valve for leakage. If the valve does leak, use the PURGER- WATER DRAIN (98A28104000000) to push (in) and release (out) the center of thevalve three or four times. No leaks are permitted.

(b) For the center-tank water drain valves:1 Push the center of the applicable water drain valve with the TOOL -

PURGING (98A28104000002) . Drain approximately 1.0 l (0.26 USgal) of fuel fromthe water drain valve.

NOTE: A rubber shield prevents fuel leakage.

2 Remove the TOOL - PURGING (98A28104000002) from the water drain valve.3 Examine the water drain valve for leakage. If the valve does leak, use the TOOL -

PURGING (98A28104000002) to push (in) and release (out) the center of the valvethree or four times. No leaks are permitted.

MECH. INSP.

NOTE: This step is very important at the center tank water drain valves 94QM and95QM, where access is not easy.

(c) Put the fuel sample into a CONTAINER-CLEAN, STERILIZED, TRANSPARENT GLASSor CONTAINER-FUEL RESISTANT, TRANSPARENT PLASTIC. If you do not do theanalysis immediately, seal the container.

(d) Do the sample removal procedure at all of the water drain valves.(2) Suction Procedure

(a) You must use an approved type of PUMP - SUCTION for use on a fuel system. You mustobey the applicable safety precautions.

(b) On the TOOL-PURGING (97A28002117002) fully retract the nut (5), the screw (4) andthe plunger assembly (1).

CAUTION: MAKE SURE THAT THE PLUNGER OF THE TOOL ALIGNS CORRECTLYWITH THE WATER DRAIN VALVE. INCORRECT ALIGNMENT OF THE TOOLCAN CAUSE:- THE WATER DRAIN VALVE TO STAY IN THE OPEN POSITION AFTER THE

TOOL IS REMOVED- A FUEL LEAK.

(c) Put the hexagonal end of the bush (2) into the bottom of the water drain valve.(d) Turn the bush (2) through 30 DEG.(e) Turn the nut (5) until it touches and seals against the bottom skin.(f) Attach the PUMP - SUCTION to the hose (3).(g) Put the outlet of the PUMP - SUCTION to the CONTAINER 10 L(2 1/2 USGAL).(h) Hold the bush (2) and turn the screw (4) clockwise to its stop. This causes the plunger (1)

to open the drain valve. Fuel can now flow into the PUMP - SUCTION.(i) Start the PUMP - SUCTION.(j) Continuously monitor the fuel flow into the CONTAINER 10 L(2 1/2 USGAL).(k) Drain approximately 1.0 l (0.26 USgal) of fuel (as a sample) from the drain valve.(l) When sufficient sample is drained, turn the screw (4) counter-clockwise to its stop.(m) Stop the PUMP - SUCTION.(n) Remove the PUMP - SUCTION from the hose (3).(o) Turn the nut (5) until it does not touch the bottom skin.(p) Turn the hexagonal end of the bush (2) 30 DEG and remove the TOOL-

PURGING (97A28002117002) .(q) Examine the drain valve for leaks.(r) Do this procedure at all of the water drain valves.

Subtask 12-32-28-750-050-AB. Water Contamination Test

MECH. INSP.

(1) Let the sample become stable.(a) If the sample moves into two layers it contains water. Continue to drain from the water

drain valve until it has no water.

WARNING: DO THE TEST ONLY IN AN APPROVED AREA. THIS WILL HELP TOPREVENT CONTAMINATION AND EXPLOSIONS.

(b) If the sample stays in one layer, it can be all fuel or all water. To find if the sample is fuelor water, do the test that follows:

ACTION RESULT1.If you have a HYDROKIT available putthe contents into the sample.

If the powder stays white, the sample isfuel and the test is complete.

or If the white powder changes color to

purple, the sample is water. Continue totake samples and test until all the waterhas been removed.

2.If you do not have a HYDROKITavailable, add water to the sample.

If the sample moves into two layers,then the sample is all fuel and the test iscomplete.

or If the sample stays in one layer, then the

sample is water. Continue to take samplesuntil all the water has been removed.

NOTE:

You can use the same procedureto do an analysis on a sample froma fuel tanker. Remove the samplefrom the supply connector of thefuel tanker.

5. Close-upSubtask 12-32-28-410-050-BA. Close Access

(1) Make sure that the work area is clean and clear of tools and other items.(2) Close the applicable access panels:

For water drain valve 94QM, close access panel 195BB For water drain valve 95QM, close access panel 196BB.

Subtask 12-32-28-942-050-AB. Removal of Equipment

(1) Make sure that the work area is clean and clear of tools and other items.NOTE: To discard the water samples, refer to the local regulations.
