Wing Fuel Boost Pump Wiring 6/2002

Applicability: All Model A319/A320/A321 aeroplanes without both Airbus Industrie modifications 30861 and 31612 embodied or Airbus Industrie Service Bulletin (SB) A320-28-1093 incorporated.

Requirement: 1. If not previously accomplished, revise the Limitations Section of the Aeroplane Flight Manual (AFM) by inserting the following:

FUEL SYSTEM

In case any wing fuel tank fuel pump circuit breaker 1QA, 2QA, 7QA or 8QA is tripped, do not re-engage.

This may be accomplished by inserting a copy of this Directive or the revised Temporary Revision 2.04.00/31 into the AFM.

2. If wing fuel tank pump circuit breaker 1QA, 2QA, 7QA or 8QA trips, either:

remove the applicable fuel pump fairing and perform visual inspections of the following to detect any damage caused by electrical arcing and, if necessary, carry out the rectification specified in sub-paragraphs 2.a.(i), 2.a.(ii) or 2.a.(iii).

(i) Electrical wiring \- If any damage to the wiring is detected replace the wire with new wire or repair it in accordance with the Aircraft Wiring Manual (AWM), Electrical Standard Practices Manual (ESPM), Chapter 20.

(ii) Fairing \- If any damage to the fairing is detected replace the fairing with a new serviceable fairing using the appropriate installation and sealing procedures.

(iii) Wing skin within the fairing area \- If any damage to the wing structure is detected repair the damaged structure in accordance with the aircraft Structural Repair Manual (SRM) or another approved method.

Caution: When replacing the fairing following the inspection, ensure that fuel boost pump wiring is not pinched or otherwise damaged. Incorrect replacement of the fairing could cause damage to the wiring.
