Airbus Model A300 B4-600R and A300 F4-600R Series Airplanes
This AD applies to Airbus Model A300 B4-605R and B4-622R airplanes, and Model A300 F4-605R and F4-622R airplanes; certificated in any category; on which Airbus Modification 4801 has been accomplished; except airplanes on which Airbus Modification 12314 has been installed in production.
The FAA is superseding an existing airworthiness directive (AD), which applies to certain Airbus Model A300 B4-600R and A300 F4-600R series airplanes. That AD currently requires repetitive inspections for damage of the center tank fuel pumps and fuel pump canisters and replacement of any damaged parts, and mandates modification of the canisters of the center tank fuel pumps, which terminates the repetitive inspections. For certain airplanes, this new AD requires a one-time inspection of the attachment bolts of the outlet flange of the canisters of the center tank fuel pumps for bolts that are too short and do not protrude through the nut, and replacement of the bolts if necessary. This AD results from several reports that the attachment bolts for the canisters, modified by the requirements in the existing AD, are too short and do not fully protrude from the nuts. We are issuing this AD 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
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hours' time-in-service or within 250 hours' time-in-service after February 8, 2000 (the effective date of AD 99-27-07 (superseded by AD 2004-23-08), amendment 39-11488), whichever occurs later, perform a detailed inspection for damage of the center tank fuel pumps and fuel pump canisters,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 (g) 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.”
(g) At the applicable time specified in paragraph (g)(1), (g)(2), or (g)(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 (i) of this AD. Accomplishment of the inspection required by this paragraph constitutes terminating action for the requirements of paragraph (f) 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.
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.
(i) Within 18 months after December 20, 2004 (the effective date of AD 2004-23-08): Modify the canisters of the center tank fuel pumps (including an operational test) by doing all the actions in accordance with paragraphs 3.A., 3.B., 3.C., and 3.D. of the Accomplishment Instructions of Airbus Service Bulletin A300-28-6069, dated September 4, 2001; Revision 01, dated May 28, 2002; or Revision 02, dated October 17, 2003. After the effective date of this AD, Revision 02 of the service bulletin must be used for accomplishing the modification. Accomplishing this modification ends the repetitive inspections required by paragraph (g) of this AD.
For airplanes on which Airbus Service Bulletin A300-28-6069, dated September 4, 2001; or Revision 01, dated May 28, 2002, has been accomplished before the effective date of this AD: Within 18 months after the effective date of this AD, perform a one-time detailed inspection of the attachment bolts of the outlet flange of the canisters of the center tank fuel pumps for bolts that are too short and do not protrude through the nut, and replace the bolts as applicable, by doing all the actions in accordance with paragraphs 3.A., 3.B., 3.C., 3.D., and 3.E. of the Accomplishment Instructions of Airbus Service Bulletin A300-28-6087, dated April 8, 2005. Do any applicable bolt replacement before further flight.
Note 2: Airplanes modified in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-28-6069, Revision 02, dated October 17, 2003, are not subject to the requirements of paragraph (j) of this AD.
