In the event of a pump failure, inspect the failed pump, the other pump located in the same half wing and their canister, and carry out any necessary rectifications in accordance with the instructions of Airbus SB A320-28-1102 Revision 2 or later DGAC approved revisions.3.

Within 162 months from first entry into service of the aircraft. |\n| | This Amendment becomes effective on 30 April 2007. |\n| Background: | On one A320 aircraft, labels were found floating in the fuel tank of the wing. These flexible plastic labels are stuck to the wing structure to identify rib numbers and manhole fastener references. The varnish coating and adhesive deteriorate in contact with fuel and the labels become detached. Floating labels in the fuel tank could be ingested by the fuel pumps which could lead to failure of the pump.The original issue of this AD addressed the identified unsafe condition by mandating an operational limitation, a repetitive inspection of fuel pumps and a repetitive inspection of fuel tanks.Amendment 1 of this AD enlarged the applicability to include MSN 982, 1051 and 1083, made reference to the latest revision status of the service documents and mandated the installation of new fuel strainers. The installation of new fuel strainers provides terminating action to the inspections detailed in this AD.Amendment 2 removes from the applicability those aircraft which were found not to be originally marked with the labels concerned by this AD.The original issue of this AD became effective on 20 July 2005.Amendment 1 of this AD became effective on 15 March 2007. |\n\n![](image.001.png) \nDavid Punshon \nDelegate of the Civil Aviation Safety Authority\n\n23 April 2007","sortOrder":0},{"sectionNumber":"AD/A320/180 Amdt 2","sectionType":"part","heading":"AD/A320/180 Amdt 2","content":"## AD/A320/180 Amdt 2","sortOrder":1},{"sectionNumber":"Fuel Tank Decals","sectionType":"part","heading":"Fuel Tank Decals","content":"## Fuel Tank Decals","sortOrder":2},{"sectionNumber":"6/2007 DM","sectionType":"part","heading":"6/2007 DM","content":"## 6/2007 DM","sortOrder":3}],"analysis":{"flash_summary_failed":{"failed":true,"reason":"A positive credit balance is required for all requests, including BYOK, so fallback providers remain available.
