SUMMARY This summary is for information only and is not approved for modification of the aircraft.
A. MODIFICATIONS
MODIFICATION CLASSIFICATION MAJOR None MINOR None NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the mass, balance, structural strength, reliability, operational characteristics affecting the airworthiness of the product. All other changes are major changes.
B. REASON
(1) History The APU Aft Fuel Feed Pump (FIN 3QC) may have a potentially unsafe condition.
Degradation of the varnish on the printed circuit board can result in arcing within the pump motor housings during specific failure case operations.
(2) Objective/Action The objective of this Service Bulletin is to identify any APU Aft Fuel Feed Pump (FIN 3QC) which may be potentially unsafe and remove them from operation.
Operators are required to inspect the Part Number of the installed APU Aft Fuel Feed Pump (FIN 3QC) and report the installed Part Number to AIRBUS.
The inspection can be satisfied either by monitoring the operator’s logbook for Part Number replacement history for the APU Aft Fuel Feed Pump (FIN 3QC) or by direct inspection on aircraft. The operator is held responsible for the accuracy of the chosen means of inspection.
Operators are further required to replace or upgrade the installed APU Aft Fuel Feed Pump (FIN 3QC), if required following inspection of the installed Part Number, and report to AIRBUS.
(3) Advantages Accomplishment of this Service Bulletin will identify and eliminate a potentially unsafe condition, if one is identified, and ensure that the operator´s aircraft has the required APU Aft Fuel Feed Pump (FIN 3QC) installed.
