A. Preparation for test

CAUTION: REMOVE THE PROTECTIVE COVERS FROM THE PROBES BEFORE YOU DO THIS PROCEDURE. IF YOU DO NOT REMOVE THEM, THE PROBES AND PROTECTIVE COVERS CAN BECOME DAMAGED OR BURNED.

(1) Remove the protective covers from the probes and sensors before you do this procedure (Ref. AMM TASK 10-11-00-555-014).

NOTE: When an engine ground run is carried out, it is necessary to enter a new flight number through the MCDU (at least one dummy character is sufficient) to get a new PFR.

(2) Obey wind limitations and safety precautions during engine ground operations (Ref. AMM TASK 71-00-00-869-005) (Ref. AMM TASK 71-00-00-869-006).
(3) Put chocks in position in front of each forward outboard Main Landing Gear (MLG)-wheel.

Tool Installation ** ON A/C NOT FOR ALL

1 Put the 98F10103500000 CHOCK-MLG,ENGINE RUN-UP in position against the wheel.
2 Pull up the tow bar in the top position until it touches the weld stops.
(4) Make sure that the engine inlet and exhaust covers are removed. Also, look at these areas to make sure that they are clear of unwanted objects.
(5) Make a visual check of the temperature sensors, fan inlet and exhaust areas. If snow or ice has collected in the fan duct, make sure that the fan turns freely. Also, make sure that the engine inlet, inlet lip, fan, spinner and fan exhaust duct are clear of ice or snow. If the fan does not turn freely melt the ice or snow with hot air before an engine operation.

WARNING: DEICING/ANTI-ICING FLUID IS DANGEROUS. USE RUBBER GLOVES AND EYE PROTECTION. KEEP THE FLUID AWAY FROM HEAT AND AN OPEN FLAME. PROVIDE ADEQUATE VENTILATION.

CAUTION: USE ONLY GLYCOL ALCOHOL AS A DEICING/ANTI-ICING MIXTURE. METHANOL CAN CAUSE CORROSION TO ENGINE PARTS MADE OF TITANIUM.

(6) If it is necessary, deice or anti-ice the fan blades with Kilfrost ABC3 (Material No.CP2499) .
(a) Prepare the deicing/anti-icing fluid with the table given below:

4. Procedure
Subtask 71-00-00-710-058-A ** ON A/C NOT FOR ALL

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:

AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:

ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.

CAUTION: DO NOT OPERATE THE ENGINE IF THE FUEL INLET PRESSURE IS NOT POSITIVE. THE FUEL IS NECESSARY TO LUBRICATE THE ENGINE FUEL PUMP AND THE HMU AND THUS PREVENT DAMAGE.

CAUTION: MONITOR THE START CYCLE VERY CAREFULLY WHEN THE STARTER AIR INLET PRESSURE IS LOWER THAN RECOMMENDED (SPECIAL OPERATION CONDITIONS). THIS CAN CAUSE LONGER TIMES TO GO TO IDLE AND HIGHER EGT PEAKS.

A. Do this test:

ACTION	RESULT
1.On the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START.	On the lower ECAM display unit: The ENGINE page comes into view. Make sure that: The air pressure is between 25 psi (1.7 bar) and 55 psi (3.8 bar). The oil quantity is correct. If necessary, fill the oil tank (Ref. AMM TASK 12-13-79-610-001). NOTE: The oil level in the oil tank can go down by 1.6 USgal (6 l) during start.
2.On the center pedestal, on the ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to ON. On the upper ECAM display unit: Monitor the important parameters N1, N2, EGT, FF. On the lower ECAM display unit: Monitor the oil pressure.	On the lower ECAM display unit, on the ENGINE page: The symbol for the starter valve opens. At approximately 16 percent N2, the A or B indication comes into view below IGN. At 50 percent N2: The symbol for the starter valve is in the closed position. The A or B indication goes out of view. NOTE: When the pack valves start to close the FAULT legend of the AIR COND PACK 1/2 pushbutton switches on the AIR COND panel 30VU come on until the pack valves are fully closed. NOTE: The engine operates at a stabilized ground idle only when there is a positive oil pressure indication.
	High oil pressure peaks can occur in cold weather because of high oil viscosity. The pressure decreases as the temperature of the oil increases. Ignition automatically starts at 16 percent N2 and the fuel automatically starts at 22 percent N2. The starter and the ignition automatically stop at approximately 50 percent N2. Engine light-off usually occurs at approximately 10 seconds after you beginning of the start attempt (starter shutoff valve open) and within 2-3 seconds after the FADEC relects the fuel on. If the engine light-off does not occur within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the ignition, the fuel flow, and dry motors the engine for 30 seconds. Twenty-five (25) seconds into the dry motoring time, the FADEC systems energizes the two igniters and at 30 seconds, selects the fuel to on. If when you tryed to start the engine for the second time there is no light-off within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the two igniters, the fuel flow and the starter. There is a dry motoring of the engine during after which the FADEC system will select a start abort. This will cause a start abort indication to come on on the upper ECAM display unit.
	If this occurs, on the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM. Set the ENG/MASTER 1(2) control switch to OFF. After the starter is cool, the operator must make a decision: try another auto or manual start or stop and correct the problem.
3.When the engine idle speed is stable, on the ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM. NOTE: It is recommended that the engine operates at or near idle for a minimum of 2 minutes before you increase to high power. You must move the throttle control lever, slowly, carefully and smoothly when possible. NOTE: You can use taxi time at or near idle as part of the 2 minute warm-up time.

5. Close-up
Subtask 71-00-00-869-071-A ** ON A/C NOT FOR ALL

A. At the end of the test stop the engine(s) (Ref. AMM TASK 71-00-00-710-028).
(1) On the overhead CTL & IND panel 25VU:
(a) Set the EXT LT/BEACON switch to OFF
(2) Stop the pneumatic supply to the aircraft:
(3) Disconnect the HP ground power unit or stop the APU.
(4) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).
