A. Preparation for Test

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.

(1) Obey the wind limitations and safety precautions during engine ground operations (Ref. AMM TASK 71-00-00-869-802) and (Ref. AMM TASK 71-00-00-869-803).
(2) Put chocks in position in front of each forward outboard MLG wheel.

NOTE: If engine start is followed by a high power run, use 98F10103500000 CHOCK-MLG,ENGINE RUN-UP.

Tool Installation

(3) Make sure that the engine inlet and exhaust covers are removed. Make sure that these areas are clear of unwanted objects.
(4) 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.
(5) If it is necessary, de-ice or anti-ice the fan blades. Refer to task Engine Start In Cold Weather Conditions (Ref. AMM TASK 12-31-71-660-803).
(6) Look at the general condition of the fan spinner and fan blades, core exhaust nozzle, LPT and external surfaces of the cowls.
(7) Make a check of the drain ports for fuel, oil and hydraulic leaks (Ref. AMM TASK 71-00-00-790-805). Also make sure that fuel drained from the engine does not cause a fire.

NOTE: In case of extreme cold weather condition (OAT < -20 deg.C), fuel leaks from the drain may occur and should not be considered as abnormal. Therefore, check for fuel leaks at the drain mast shall be performed with the engine fully stabilized at idle.

(8) Remove covers from TAT, AOA, and PITOT probes.

(8) On the HYD/FUEL panel 40VU:
(a) If there is fuel in the Center tank, make sure that MODE SEL is in AUTO (the MAN legend off).
(b) Push all the FUEL/PUMPS pushbutton switches (the OFF legends of these pushbutton switches go off).
(9) Supply the aircraft pneumatic system from a HP ground power unit or the APU (Ref. AMM TASK 36-12-00-860-805) or (Ref. AMM TASK 36-12-00-860-806).

NOTE: The minimum recommended starter air supply pressure is 25 PSI, when the start valve is open.
Two external pneumatic power units may be used in parallel, if the pressure/flow relation is expected to be marginal.

(10) On the overhead CTL & IND panel 25VU:
(a) Set the EXT LT/BEACON switch to ON.

4. Procedure
Subtask 71-00-00-710-281-A

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.

WARNING: SET THE THRUST LEVERS TO IDLE BEFORE YOU START THE ENGINE. IF YOU DO NOT DO THIS, THE THRUST LEVEL WILL RAPIDLY INCREASE AND CAN CAUSE DANGEROUS CONDITIONS.

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 ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START. Before you start, it is recommended to erase all the engine alerts and warnings.	On the lower ECAM Display Unit (DU): The ENGINE page comes into view. Make sure that: The recommended minimum starter air-pressure with the start valve open is 25 psi (2 bar) after the start. The oil quantity is correct. If necessary, fill the oil tank (Ref. AMM TASK 12-13-79-610-805). NOTE: The oil level in the oil tank can decrease by 1.85 USgal (7.0 l) during the start.
2.On OVERHEAD CTL & IND panel 22VU: Push the ENG/MAN/START/1(2) pushbutton switch.	The ON legend of this pushbutton switch comes on. On the lower ECAM DU, on the ENGINE page: The symbol for the starter valve is in the open position.
3.Make sure that the engine operates: Push the ENG/MAN/START/1(2) pushbutton switch.	On the lower ECAM DU, on the ENGINE page: Make sure that the oil pressure indication is positive. NOTE: In cold weather conditions, important oil pressure surges can occur. NOTE: The oil level in the oil tank decreases by 1.85 USgal (7.0 l). NOTE: If you use a starter air pressure that is less than the recommended level, a slow N2 acceleration and a subsequent rpm hang-up can occur. Make sure that you obey the starter limits that follow: The starter is not engaged when the core speed is above 63 percent. The permitted duty cycles completed with one of the two procedures that follow: * Three cycles one after the other. Each cycle has a duration of two minutes and there is a rest period of 60 seconds at the end of each cycle. After these three cycles, wait for 15 minutes to let the starter become cool before you try a new start or motoring. * One five-minute cycle followed by a cooling period of five minutes.This cycle is applicable for periodic maintenance activities.
4.When N2 gets the maximum motoring speed (minimum 20 percent) and one minute after the ENG/MAN/START/1(2) pushbutton switch is pushed, on ENG panel 115VU: Set the ENG/MASTER 1(2) control switch to ON. On the upper ECAM DU: Monitor main parameters N1, N2, EGT and FF. On the lower ECAM DU: Monitor the oil pressure.	On the lower ECAM DU, on the ENGINE page: The AB indication comes into view below IGN. At a minimum of 63 percent N2: The symbol for the starter valve is in the closed position. The AB indication goes out of view. NOTE: The stall and low fan speed indications will show on the upper ECAM DU. Because the automatic start sequence is bypassed, abort the start when the parameters are near or above the limits. Refer to the notes. NOTE: The engine light-off will usually occur two to three seconds after you set the ENG MASTER control lever to the ON position. If the light-off does not occur in 15 seconds, abort the start. NOTE: Immediately abort the start if: The Exhaust Gas Temperature (EGT) quickly increases, and A slow N2 acceleration occurs. These can be the symptoms of: An incorrect fuel scheduling A faulty instrumentation Engine damage A low starter air-pressure or too much engine damage. Monitor the upper ECAM DU for possible messages. You can continue a start with a slow N2 acceleration from light-off to idle, and a low EGT indication (unsatisfactory fuel schedule). You must correct the start with temperatures of more than 1337 deg.F (725 deg.C). The temperatures of a usual start are less than 932 deg.F (500 deg.C).
5.When the engine idle speed is stable, on ENG panel 115VU: Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.	NOTE: When the engine is at idle, the oil pressure must be positive. You must immediately stop the engine if you have a stable pressure that is below a minimum of 17 psi (1 bar). During cold weather operations, oil pressure surges to full scale can occur because of high oil viscosity. The pressure must decrease while the oil temperature increases. Thus, if the oil pressure stays above the usual range after the oil temperature is stable in the limits, you must stop the engine and examine the cause.
6.On OVERHEAD CTL & IND panel 22VU: Release the ENG/MAN/START/1(2) pushbutton switch.	The ON legend of this pushbutton switch goes off. NOTE: It is recommended that the engine operates at or near idle for a minimum of three minutes before you increase it to high power. You can use the taxi-time at or near idle as part of the three minutes warm-up time.
