WARNING : DO NOT CLOSE AN OPEN (TRIPPED) CIRCUIT BREAKER RELATED TO A
_______ FUEL-PUMP. IF YOU CLOSE THE CIRCUIT BREAKER, THERE IS A RISK:
- OF FIRE OR OF AN EXPLOSION
- OF DAMAGE TO THE AIRCRAFT WIRING AND STRUCTURE.
(1) Examine the C/B-FUEL/CTR TK/PUMP2 SPLY (30QA).

- C/B-29QA(30QA) Tripped (Ref. TASK 28-21-00-810-829).
(b) Is closed (set), do the Functional Test of the Center-Tank Fuel Control (Manual Mode) (Ref. AMM TASK 28-21-00-720-001).
4. Fault Isolation
_______________
A. Procedure
(1) If a fuel low pressure indication is shown for the center tank fuel pump No. 2 (38QA):
- do a fuel transfer, (Ref. AMM TASK 28-21-00-710-007) use the center tank fuel pump No. 2 to do the fuel transfer.
(2) If the fuel starts to transfer go to step (3). If the fuel does not start to transfer:
(a) Set the CTR TK PUMP 2 P/BSW (34QA) to OFF (release out). This will de-energize the contactor 36QA.
(b) Open the right main landing gear door for access (Ref. AMM TASK 32-12-00-010-001).
(c) Get access to the center tank fuel pump No. 2, 38QA (Ref. AMM TASK 28-21-51-000-002).
(d) Before you do more steps make sure that fuel from a leak or spillage does not contaminate the areas (in zones 148 and 196) that follow:
- the center tank bottom skin adjacent to the right fuel pump 38QA
- the hydraulic compartment below the wing box (center tank) and forward side of the rear bulkhead at FR42
- the rear wall (spar) of the center tank in the right main landing gear bay
- the rear side of the bulkhead at FR 42 below the center tank.
1 If necessary:
_ a Repair all the leaks:
_
- (Ref. AMM TASK 51-76-12-300-001)
- (Ref. AMM TASK 51-76-12-300-002).
b Clean the area of the fuel spillage.
_
c Clean and dry the fuel pump supply cable and the end
_
connector 38QA-A.

(e) Disconnect the supply cable end connector 38QA-A from the fuel pump receptacle.
(f) If, in step (d) or (e), any damage can be seen in this area, go to step (k) 1_.
(g) Set the CTR TK PUMP 1 P/BSW (33QA) to ON (push in). This will energize the contactor 36QA and the 115VAC three phases will be supplied to the fuel pump connector 38QA-A.
(h) Do a test with an (intrinsically safe) multimeter to make sure that each of the 115VAC three phases are available at the connector 38QA-A (Ref. ASM 28-21/03).
(i) Set the CTR TK PUMP 2 P/BSW (34QA) to OFF (release out). This will de-energize the contactor 36QA. 中國航空網(wǎng) www.k6050.com 航空翻譯 www.aviation.cn 本文鏈接地址：A320 Trouble Shooting Manual 排故手冊 FUEL 燃油1(128)
