Applicability: Model A300 B4-600R and A300 F4-600R series airplanes, certificated in any category, on which Airbus Modification 4801 (trim tank system) has been accomplished. Compliance: Required as indicated, unless accomplished previously. To prevent damage to the fuel pump and fuel pump canister, which could result in loss of flame trap capability and could provide a fuel ignition source in the center fuel tank, accomplish the following: Restatement of Requirements of AD 99-27-07 Inspections (a) Prior to the accumulation of 5,000 total hours, time-in-service or within 250 hours time-in-service after February 8, 2000 (the effective date of AD 99-27-07, amendment 39-11488), whichever occurs later, perform a detailed inspection for damage of the center tank fuel pumps and fuel pump canisters, in accordance with Airbus All Operators Telex (AOT) 28-09, dated November 28, 1998. Repeat the inspection prior to the accumulation of 12,000 total hours time-in-service, or within 250 hours time-in-service after accomplishment of the initial inspection, whichever occurs later. Thereafter, repeat the inspection at intervals not to exceed 250 hours time-in-service, until accomplishment of the initial inspection required by paragraph (b) of this AD. 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." (b) At the applicable time specified in paragraph (b)(1), (b)(2), or (b)(3) of this AD: Perform a detailed inspection to detect damage of the center tank fuel pumps and perform an eddy current inspection to detect damage of the fuel pump canisters, in accordance with Airbus Alert Service Bulletin A300-28A6061, dated February 19, 1999; or Airbus Service Bulletin A300-28-6061, Revision 04, dated August 1, 2002. Repeat the inspections thereafter at intervals not to exceed 1,500 flight cycles, until accomplishment of paragraph (d) of this AD. Accomplishment of the initial inspections required by this paragraph constitutes terminating action for the requirements of paragraph (a) of this AD. (1) For airplanes that have accumulated 11,000 or more total flight cycles as of February 8, 2000: Inspect within 300 flight cycles after February 8, 2000. (2) For airplanes that have accumulated 8,500 or more total flight cycles, but fewer than 11,000 total flight cycles, as of February 8, 2000: Inspect within 750 flight cycles after February 8, 2000. (3) For airplanes that have accumulated fewer than 8,500 total flight cycles as of February 8, 2000: Inspect prior to the accumulation of 7,000 flight cycles, or within 1,500 flight cycles after February 8, 2000, whichever occurs later. Corrective Action (c) If any damage is detected during any inspection required by this AD, prior to further flight, replace the damaged fuel pump or fuel pump canister with a new or serviceable part in accordance with Airbus Alert Service Bulletin A300-28A6061, dated February 19, 1999; or Airbus Service Bulletin A300-28-6061, Revision 04, dated August 1, 2002. New Requirements of This AD Modification (d) Within 18 months after the effective date of this AD: Modify the canisters of the center tank fuel pumps (including an operational test) by doing all the actions per paragraphs 3.A., 3.B., 3.C., and 3.D. of the Accomplishment Instructions of Airbus Service Bulletin A300-28-6069, Revision 01, dated May 28, 2002. Accomplishment of this modification ends the repetitive inspections required by paragraph (b) of this AD. (e) Accomplishment of the modification before the effective date of this AD per Airbus Service Bulletin A300-28-6069, dated September 4, 2001, is acceptable for compliance with the modification required by paragraph (d) of this AD.
