### TITLE: FUEL- MAIN FUEL PUMP SYSTEM - INTRODUCE GROUND FAULT INTERRUPTERS (GFI) TO CENTER TANK FUEL PUMPS **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR 150736J3138 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. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The center tank fuel pumps (Pump 1 FIN 37QA / Pump 2 38QA) are supplied by control relays (FIN 35QA / 36QA). These relays are installed in electrical panel 107VU. To protect the pump feeder supply cable from the electrical panel 107VU and the pump windings against ’earth’ faults, additional earth leakage protection is required. Mod. No. 150690J2866 was issued to evaluate the additional earth leakage protection available by replacing a control relay with Ground Fault Interrupter (GFI). As a result of this mod, an evaluation Service Bulletin A320-28-1903 was issued to some operators to evaluate the application of Mod. No. 150690J2866. Additional earth leakage protection was evaluated through installation of a GFI 70QA in electrical panel 107VU instead of control relay FIN 36QA. This Service Bulletin introduces Mod. No. 150736J3138. This modification introduces GFIs and related bases into the electrical supply circuits of the center tank fuel pump 1 (FIN 37QA) and pump 2 (FIN 38QA) on A318, A319 and A320 aircraft. These GFIs have the same ’footprint’ as the existing relay/micro-contactors and physically replace them on the electrical panel. The new GFI sockets are fool-proofed to prevent incorrectly fitment of a normal relay/micro-contactor or inappropriate GFI device.

# @A318/A319/A320/A321 SERVICE BULLETIN SUMMARY These GFIs will replace the existing 3-phase relay/micro-contactors. The function of the GFI is to electrically isolate the pump if a ground fault condition occurs downstream of the GFI. The GFI gives additional earth leakage protection to the downstream circuit. Accomplishment of this Service Bulletin will not change the characteristics of the aircraft.

**CONF 002, 004, 006 thru 007 MATERIAL QTY PER A/C SEE NOTES Consumable CMLA01 1 Kit 281188A02R00 1 **CONF ALL B. CONCURRENT REQUIREMENTS None C. REASON (1) History The center tank fuel pumps (Pump 1 FIN 37QA / Pump 2 38QA) are supplied by control relays (FIN 35QA / 36QA). These relays are installed in electrical panel 107VU. To protect the pump feeder supply cable from the electrical panel 107VU and the pump windings against ’earth’ faults, additional earth leakage protection is required. Mod. No. 150690J2866 was issued to evaluate the additional earth leakage protection available by replacing a control relay with Ground Fault Interrupter (GFI). As a result of this mod, an evaluation Service Bulletin A320-28-1903 was issued to some operators to evaluate the application of Mod. No. 150690J2866. Additional earth leakage protection was evaluated through installation of a GFI 70QA in electrical panel 107VU instead of control relay FIN 36QA. (2) Objective/Action This Service Bulletin introduces Mod. No. 150736J3138. This modification introduces GFIs and related bases into the electrical supply circuits of the center tank fuel pump 1 (FIN 37QA) and pump 2 (FIN 38QA) on A318, A319 and A320 aircraft. These GFIs have the same ’footprint’ as the existing relay/micro-contactors and physically replace them on the electrical panel. The new GFI sockets are fool-proofed to prevent incorrectly fitment of a normal relay/micro-contactor or inappropriate GFI device. (3) Advantages These GFIs will replace the existing 3-phase relay/micro-contactors. The function of the GFI is to electrically isolate the pump if a ground fault condition occurs downstream of the GFI. The GFI gives additional earth leakage protection to the downstream circuit. Accomplishment of this Service Bulletin will not change the characteristics of the aircraft. (4) Operational/Maintenance Consequences None

# @A318/A319/A320/A321 SERVICE BULLETIN (2) Accomplishment Timescale Accomplishment of this Service Bulletin is recommended at or before 48 months from the issue of this Service Bulletin. This Service Bulletin has been classified Recommended. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to change this classification to Mandatory. It is anticipated that the AD will confirm the (thresholds and/or intervals and/or date) given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale. F. APPROVAL The technical content of this document is approved under the authority of Design Organization Approval No. EASA.21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances. The estimates do not include the time to prepare, plan or inspect the work. Manufacture and procurement of parts and tools, drying times for paints, sealants, etc., and general administration work are also not included. **CONF 001 Task 281188-831-895-001: MODIFICATION Get Access 2.00 On Aircraft Modify the Equipment and the Wiring in the Contactor Box 107VU 3.00 Tests 1.50 Close-Up 1.50 TOTAL MANHOURS 8.00 ELAPSED TIME (HOURS) 8.00 **CONF 002 Task 281188-831-895-001: MODIFICATION Get Access 2.00 On Aircraft Modify the Equipment and the Wiring in the Contactor Box 107VU 6.00 Tests 1.50 Close-Up 1.50
