Airworthiness Directive · Amendment 39-17826 · Wings
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2017-15-03. Comply with the one in force.
This AD applies to Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; and Airbus 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 adopting a new airworthiness directive (AD) for certain Airbus Model A300 B4-600 and A300 B4-600R series airplanes. This AD was prompted by reports of cracks found in certain bottom wing skin stringers during full-scale fatigue testing and in service. This AD requires modifying the profile of stringer run-outs of both wings, including a high frequency eddy current inspection of the fastener holes for defects and, if necessary, repairs. We are issuing this AD to prevent cracking in the bottom wing skin stringers, which could result in reduced structural integrity of the wings.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Before the accumulation of 42,500 total flight cycles, or within 2,000 flight cycles after the effective date of this AD, whichever occurs later, 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 Mandatory Service Bulletin A300-57-6046, Revision 02, dated June 21, 2013, except as required by paragraph (h) of this AD. Do all applicable repairs before further flight.
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.
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.
