Airworthiness Directive · Amendment 39-18963 · Wings
Airbus Airplanes
This AD applies to Airbus Model A300-B4-601, B4-603, B4-620, and B4-622 airplanes, and Model A300-B4-605R and B4-622R airplanes, certificated in any category, except airplanes on which Airbus Modification 10324 or 10325 has been embodied in production.
We are superseding Airworthiness Directive (AD) 2014-08-02 which applied to certain Airbus Model A300 B4-600 and A300 B4-600R series airplanes. AD 2014-08-02 required modifying the profile of stringer run-outs of both wings, including a high frequency eddy current (HFEC) inspection of the fastener holes for defects, and repairs if necessary. This new AD retains the actions required by AD 2014-08-02 and revises the compliance times. This AD was prompted by further analysis in the context of widespread fatigue damage (WFD), which concluded that shorter compliance times are necessary to meet specified requirements to address WFD. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2014-08-02, with revised compliance times and service information. At the time specified in paragraph (g)(1) or (g)(2) of this AD, whichever occurs earlier, modify the profile of stringer run-outs at rib 14 of both wings, including a high frequency eddy current inspection of the fastener holes for defects and all applicable repairs, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-57-6046, Revision 02, dated June 21, 2013; or Revision 03, including Appendix 01, dated February 4, 2015; except as required by paragraph (h) of this AD. Do all applicable repairs before further flight. As of the effective date of this AD, only Airbus Service Bulletin A300-57-6046, Revision 03, including Appendix 01, dated February 4, 2015, may be used.
(1) Before the accumulation of 42,500 total flight cycles, or within 2,000 flight cycles after May 21, 2014 (the effective date of AD 2014-08-02), whichever occurs later.
(2) Before the accumulation of 30,000 total flight cycles, or within 2,000 flight cycles after the effective date of this AD, whichever occurs later.
This paragraph restates the requirements of paragraph (h) of AD 2014-08-02, with revised service information.
(1) Where Airbus Mandatory Service Bulletin A300-57-6046, Revision 02, dated June 21, 2013, specifies to contact Airbus for repair instructions, this AD requires contacting the Manager, ANM-116, International Branch, Transport Airplane Directorate, FAA, or the European Aviation Safety Agency (EASA) (or its delegated agent) for repair instructions and doing those repairs before further flight.
(2) Where Airbus Service Bulletin A300-57-6046, Revision 03, including Appendix 01, dated February 4, 2015, specifies to contact Airbus for appropriate action: Before further flight, accomplish corrective actions in accordance with the procedures specified in paragraph (j)(2) of this AD.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
