Airbus Model A300 B4 Series Airplanes; Model A300 B4-600 Series Airplanes; Model A300 C4-605R Variant F Airplanes; Model A310-200 Series Airplanes; and Model A310-300 Series Airplanes
This AD applies to the Airbus airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; and Model A300 C4-605R Variant F airplanes; except those airplanes equipped with a fuel trim tank system (that have incorporated Airbus Modification 4801).
(2) All Model A300 B4-2C, B4-103, and B4-203 airplanes; Model A310-203, -204, -221, and -222 airplanes; and Model A310-304, -322, -324, and -325 airplanes.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B4-600 and A300 C4-600 series airplanes. That AD currently requires a one-time inspection to detect damage of the pump diffuser guide slots (bayonet) of the center tank fuel pumps, the pump diffuser housings, and the pump canisters; repetitive inspections to detect damage of the fuel pumps and the fuel pump canisters; and corrective action, if necessary. This new AD adds, for new airplanes, repetitive inspections of the pump bodies for cracking, damage, and missing and broken fasteners; repetitive inspections of the fuel pump canisters for a cracked flange web; and corrective actions if necessary. For all airplanes, this new AD also adds replacement of the fuel pump canisters with new reinforced fuel pump canisters, which ends the repetitive inspections. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to detect and correct damage of the center tank fuel pumps and fuel pump canisters, which could result in separation of a pump from its electrical motor housing, loss of flame trap capability, and a possible fuel ignition source in the center fuel tank.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes and Model A300 C4-605R Variant F airplanes: Within 15 days after May 19, 2004 (the effective date of AD 2004-08-03) (unless accomplished previously), perform detailed inspections as specified in paragraphs (f)(1) and (f)(2) of this AD, in accordance with paragraph 4.2 of Airbus All Operators Telex (AOT) A300-600-28A6075, dated February 20, 2003; or Revision 01, dated October 24, 2005.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive examination of a specific item, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at an intensity deemed appropriate. Inspection aids such as mirror, magnifying lenses, etc., may be necessary. Surface cleaning and elaborate procedures may be required.”
(1) Inspect the lower part of the pump diffuser guide slots (bayonet) of the center tank fuel pumps and the bottom of the pump diffuser housings to detect cracks, fretting, and other damage. Replace any damaged pump and the corresponding fuel pump canister with new parts before further flight in accordance with the AOT.
(2) Inspect the center tank fuel pump canisters to detect cracks. Replace any cracked fuel pump canister and the corresponding fuel pump with new parts before further flight in accordance with the AOT.
For Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes and Model A300 C4-605R Variant F airplanes: Within 600 flight hours after May 19, 2004, perform a detailed inspection of the fuel pumps, and an eddy current inspection of the fuel pump canisters, to detect damage. Do the inspections in accordance with paragraph 4.3 of Airbus AOT A300-600-28A6075, dated February 20, 2003; or Revision 01, dated October 24, 2005. Replace any damaged part with a new part before further flight in accordance with the AOT. Repeat the inspections at intervals not to exceed 3,000 flight cycles.
(h) For Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes and Model A300 C4-605R Variant F airplanes: Within 7,000 flight cycles after canister replacement as specified in paragraph (g) of this AD, perform an eddy current inspection of the fuel pump canisters to detect damage in accordance with Airbus AOT A300-600-28A6075, dated February 20, 2003; or Revision 01, dated October 24, 2005. Replace any damaged part with a new part before further flight in accordance with the AOT. Thereafter repeat the inspection at intervals not to exceed 3,000 flight cycles.
Note 2: Airbus AOT A300-600-28A6075 refers to Airbus Alert Service Bulletin A300-28A6061, Revision 04, dated August 1, 2002, as an additional source of service information for accomplishment of the eddy current inspection required by paragraphs (g) and (h) of this AD.
(i) For Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes and Model A300 C4-605R Variant F airplanes: At the applicable time specified in paragraph (i)(1) or (i)(2) of this AD, submit a report of findings (both positive and negative) of each inspection required by this AD, in accordance with Airbus AOT A300-600-28A6075, dated February 20, 2003. Information collection requirements contained in this AD have been approved by the Office of Management and Budget (OMB) under the provisions of the Paperwork Reduction Act of 1980 (44 U.S.C. 3501 et seq.) and have been assigned OMB Control Number 2120-0056.

(2) For any inspection accomplished before May 19, 2004: Submit the report within 10 days after May 19, 2004.
For Model A300 B4-2C, B4-103, and B4-203 airplanes; Model A310-203, -204, -221, and -222 airplanes; and Model A310-304, -322, -324, and -325 airplanes: At the applicable compliance time specified in paragraphs (j)(1) and (j)(2) of this AD, do a detailed inspection of the pump bodies for cracking, damage, and missing and broken fasteners; and do a high frequency eddy current (HFEC) inspection of the fuel pump canisters for a cracked flange web, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-0084, excluding Appendix 01, dated June 28, 2005 (for Model A300 B4-2C, B4-103, and B4-203 airplanes); or Airbus Service Bulletin A310-28-2159, excluding Appendix 01, dated June 28, 2005 (for Model A310-203, -204, -221, and -222 airplanes and Model A310-304, -322, -324, and -325 airplanes), as applicable. If any crack or damage to the pump bodies is found or any missing or broken fastener is found, before further flight, replace the fuel pump with a new fuel pump in accordance with the applicable service bulletin. Repeat the detailed inspection of the pump bodies thereafter at intervals not to exceed 3,000 flight cycles. If no cracked flange web is found, repeat the HFEC inspection of the fuel pump canisters thereafter at intervals not to exceed 3,000 flight cycles. Accomplishing the replacements specified in paragraph (1) of this AD terminates the repetitive detailed and HFEC inspections.
(1) For Model A300 B4-2C, B4-103, and B4-203 airplanes: Inspect before the airplane has accumulated 19,600 total flight cycles, or within 1,000 flight cycles after the effective date of this AD, whichever is later.
