(1) Examine the C/B-FUEL/L WING TK/PUMP 1 SPLY (1QA).
(2) If the C/B-1QA:
(a) Is open (tripped), do Fuel - L(R) Wing Tank Pumps 1, Power Supply (Normal) - C/B-1QA(2QA) Tripped (Ref. TASK 28-21-00-810-827).
(b) Is closed (set), do the Operational Test of the Wing-Tanks Fuel Control (Ref. AMM TASK 28-21-00-710-001).

A. Procedure
(1) If a fuel low pressure indication is shown for the left wing tank fuel pump No. 1 (21QA):
- do a fuel transfer (Ref. AMM TASK 28-21-00-710-007) use the left wing tank fuel pump No. 1 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 L TK PUMPS 1 P/BSW (13QA) to OFF (release out). This will de-energize the contactor 17QA.
(b) Before you do more steps, make sure that the wing area adjacent to the left outer fuel pump 21QA fairings and cover is not contaminated with fuel from a fuel leak or spillage.
1 If necessary:
_ a Repair all the leaks:
_
- (Ref. AMM TASK 51-76-12-300-001)
- (Ref. AMM TASK 51-76-12-300-002)
- (Ref. SIL 57-0086).
b Clean the area of the fuel spillage.
_
(c) Remove all the fuel pump 21QA cable fairings (Ref. AMM TASK 28-21-49-000-001) and cover assembly (Ref. AMM TASK 28-21-51-000-001). 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 FUEL 燃油1(65)
