4. Procedure
Subtask 71-00-00-710-132-F ** ON A/C NOT FOR ALL
A. Do the Normal Engine Manual Start Procedure as follows:
   (1) General
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: REVERSE WINDMILLING CAN OCCUR IF THE AIRCRAFT IS OPEN TO A STRONG TAIL WIND. CAREFULLY MONITOR THE START TO PREVENT A HOT START. REFER TO WIND DIRECTION AND VELOCITY OPERATIONAL LIMITATIONS DIAGRAM.
     (a) Do each step of the procedure in sequence. If you abort the start, you must do each step of the sequence again.
F Start Fault Diagnostics ** ON A/C NOT FOR ALL
     (b) During the start, keep the service air bleed inputs and accessory load to a minimum.
       1 If a tail wind prevents an easy start, position the aircraft toward the wind (Ref. AMM TASK 71-00-00-860-012).
   (2) Fill the oil tank by the procedure that follows to avoid overfilling the system
     (a) If the engine was shut down for more than 10 hours, motor the engine with the starter for a minimum of two minutes. Check the oil level after the rotor stops. Fill the oil tank as necessary (Ref. AMM TASK 12-13-79-610-011).
     (b) If the engine was shut down for less than 10 hours, check the oil level. Fill the oil tank as necessary (Ref. AMM TASK 12-13-79-610-011).
     (c) Before the first start after an overhaul, or if you drained the fuel or the oil compartments to repair the engine, prime the oil and fuel systems (Ref. AMM TASK 71-00-00-860-013).
CAUTION: THE HPC AND HPT ROTORS WILL HAVE IMPORTANT DAMAGE IF YOU DO NOT OBEY THE INSTRUCTION GIVEN IN THE TASK SPECIFIED BELOW.
   (3) Before engine start refer to procedure for a Bowed Rotor Start Prevention (Ref. AMM TASK 71-00-00-700-016).
   (4) Do the engine start
ACTION
RESULT
1.On the ENG panel 115VU:
  • Put 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 30 psi (2.1 bar) and 40 psi (2.8 bar).
    The oil quantity is correct.
NOTE: After IGN/START selection, wait about 5 seconds before selecting ENG MAN START ON.
2.On the OVERHEAD control and indicating panel 22VU:
  • Push the ENG/MAN START/1(2) pushbutton switch. Simultaneously start the timer for 30 seconds to perform a dry crank.
  • The ON legend of this pushbutton switch comes on.
  • On the lower ECAM display unit, on the ENGINE page:
    The symbol for the starter valve is in the open position.
NOTE: For second engine start, wait about 5 seconds after the electrical power transient (at 50 percent N2) before selecting the second ENG MAN START ON.
3.Make sure that the engine operates.
  • On the lower ECAM display unit, on the ENGINE page:
    Make sure that the oil pressure indication is positive.
NOTE: During pack valves closing, the FAULT legends of the AIR COND/PACK pushbutton switches come on until the pack valves are fully closed.
4.After 30 seconds on the ENG panel 115VU:
  • Set the ENG/MASTER 1(2) control switch to ON.
On the lower ECAM display unit, on the ENGINE page:
  • The AB indication comes into view below IGN
5.On the upper ECAM display unit:
  • Monitor the management parameters (EPR, N1, N2, EGT and FF).
At 43 percent N2:
The symbol for the starter valve is in the closed position.
  • The AB indication goes out of view.
6.On the lower ECAM display unit:
  • Monitor the oil pressure.

CAUTION: AFTER A FAILED OR ABORTED START, IF YOU DO AN AUTOMATIC START WHEN N2 IS MORE THAN 10%, THERE IS A RISK OF EGT OVERTEMPERATURE.
CAUTION: IF YOU FAIL TO DO THE STEPS THAT FOLLOW, A HUNG START CAN BE THE RESULT.
   (5) Monitor the engine start
NOTE: If you abort a start, do a manual start for the next start.
     (a) Monitor the N2 and the EGT carefully during the start for any unusual indications. Sluggish N2 acceleration is an indication of a possible hot or hung start. If this indication is accompanied by a fast increase in EGT, abort the start immediately.
     (b) If the EGT is more than the start temperature limit, shut the engine down immediately. Write down the length of the time and the highest temperature during overtemperature TSM 77-00-00-810-930 and TSM 77-00-00-810-931.
     (c) Abort the start if N1 turn does not occur immediately after an increase in EGT or by the time N2 is more than 34 percent.
     (d) Abort the start if more than 90 seconds is necessary for the engine to accelerate from FUEL ON to idle N2.
     (e) Abort the start if the EGT does not increase in less than 20 seconds after FUEL ON.
     (f) Abort the start if the fuel or ignition is accidentally stopped.
     (g) Abort the start if the oil pressure does not increase.
NOTE: If you abort the start, perform a dry motoring (Ref. AMM TASK 71-00-00-710-045) for 30 seconds to remove caught fuel or gases or until the EGT decreases below 250 deg.C (482 deg.F).
     (h) Make sure that EGT, N1 and N2 increase in less than 20 seconds (upper ECAM).
     (i) Make sure that the EGT has an usual increase.
     (j) Make sure that N1 and N2 have usual acceleration.
     (k) Continue to motor the engine until the EGT peaks, decreases, then becomes stable at MIN IDLE.
     (l) When the engine idle speed is stable, on the panel 115VU:
  • Put the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.
NOTE: POST SB 31-1331 only: When the engine start sequence has ended and the engine is at or above idle (with TLA<8°): on the upper ECAM DU, "AVAIL" is displayed in green (10 seconds) in the middle of the EPR dial in order to indicate that the engine start is successful.
     (m) On the panel 22VU:
       1 Release the ENG/MAN/START/1(2) pushbutton switch.
  • The ON legend of this pushbutton switch goes off.
   (6) Engine Warm-Up
     (a) No minimum warm-up time is necessary after a usual engine shutdown if the engine is started again in less than two hours.
     (b) If the engine was shutdown for more than two hours, operate the engine at MIN IDLE for five minutes. This keeps thermal stresses to a minimum. The engine must be warmed-up until the oil temperature is a minimum of -10 deg.C (+14 deg.F) before you move the throttle control lever forward.
