| Requirement: | 1. Unless already accomplished in accordance with AD/A320/102, relocate the relay 11QG from relay box 103VU to the shelf 95VU in accordance with the instructions given in SB A320-24-1092 Revision 4.2. Unless already accomplished in accordance with AD/A320/102, for aircraft on which SB A320-24-1092 original issue or Revision 1 or Revision 2 have been received, verify that:a. the 4 contacts installed in terminal block FIN209VT12 correspond to part number (P/N) NSA937910EA2000,b. if the P/N is different from NSA937910EA2000, install contacts P/N NSA937910EA2000 in accordance with the instructions given in SBA320-24-1092 Revision 3 or Revision 4.3. Unless already accomplished, perform the additional test required after the relocation of the relay 11QG, in accordance with SB A320-24-1092 Revision 4.Note: DGAC AD 2002-365(B) refers. |
| Compliance: | For Requirements 1 and 2 - before 15 May 2000, or within 500 hours time in service after 9 September 1999 or before further flight.For Requirement 3 - Within 600 flight hours from the original effective date of this AD (3 October 2002). |

| Background: | AD/A320/102 was based on DGAC AD 1999-263-134(B), mandating the embodiment of Service Bulletin (SB) A320-24-1092 Revision 3. The SB calls for the relocation of the engine/master 1 relay 11QG to avoid any risk of simultaneous cut-off of the fuel supply to both engines by the low pressure shut-off valves by water ingress in relay box 103VU. Revision 3 replaced Revisions 1 and 2 which contained erroneous instructions. |
| On 20 July 2002, DGAC AD 1999-263-134(B) was cancelled and replaced with DGAC AC 2002-365(B) which mandates the adherence to SB A320-24-1092 Revision 4. It requires additional testing following the relay relocation.Amendment 1 is issued to reflect the cancellation of DGAC AD 1999-263-134(B) and release of DGAC AC 2002-365(B) which mandates SB A320-24-1092 Revision 4.This AD replaces AD/A320/102 which is cancelled. It incorporates the initial requirements of DGAC AD 1999-263-134(B). |
