We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
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, reinforce the fuselage butt joint at FR 58 in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-53-6146, Revision 01, including Appendix 1, dated June 26, 2009.
(h) Accomplishment of the requirements of paragraph (g) of this AD terminates Airworthiness Limitations Items (ALI) Tasks 53.16.04-01-1 and 53.16.22-01-1 for these airplanes.
Note 1: In case of earlier accomplishment of Airbus Mandatory Service Bulletin A300-53-6146, Revision 01, dated June 26, 2009, before the recommended thresholds contained in the Threshold Table in paragraph 1.E.(2) of Airbus Mandatory Service Bulletin A300-53-6146, Revision 01, dated June 26, 2009, are reached, the operator should contact Airbus to define an additional appropriate inspection program.
Note 2: This AD differs from the MCAI and/or service information as follows: No differences.
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.
