AD 99-27-07

Required as indicated, unless accomplished previously.

To detect 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:

Inspections

(a) Prior to the accumulation of 5,000 total hours time-in-service, or within 250 hours time-in-service after the effective date of this AD, whichever occurs later, perform a detailed visual 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 2: For the purposes of this AD, a detailed visual inspection is defined as: ``An intensive visual examination of a specific structural area, system,installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by

the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access 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 visual 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. Repeat the inspections thereafter at intervals not to exceed 1,500 flight cycles. 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 the effective date of this AD: Inspect within 300 flight cycles after the effective date of this AD.

(2) For airplanes that have accumulated 8,500 or more total flight cycles, but fewer than 11,000 total flight cycles, as of the effective date of this AD: Inspect within 750 flight cycles after the effective date of this AD.

(3) For airplanes that have accumulated fewer than 8,500 total flight cycles as of the effective date of this AD: Inspect prior to the accumulation of 7,000 flight cycles, or within 1,500 flight cycles after the effective date of this AD, whichever occurs later.

(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.
