Airworthiness Directive · Amendment 39-15241 · Fuselage
Airbus Model A300-600 Series Airplanes
Superseded. A later AD replaced this one: AD 2019-05-13. Comply with the one in force.
This AD applies to Airbus Model A300-600 series airplanes, manufacturing serial numbers (MSN) 0815 up to MSN 0821 inclusive, certificated in any category.
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:
Unless already done, do the following actions.
(1) Action No. 1, for the center wing box:
(i) At the later of the times in paragraphs (f)(1)(i)(A) and (f)(1)(i)(B) of this AD: Do an external ultrasonic inspection for cracking of the taperlocks fasteners of the center wing box, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006. If any crack is detected: Before further flight, contact Airbus for repair instructions, and repair.
(A) Before the accumulation of 19,800 total flight cycles or 41,200 total flight hours, whichever occurs first.
(B) Within 3 months after the effective date of this AD.
(ii) Repeat the inspection thereafter at intervals not to exceed 3,300 flight cycles or 6,900 flight hours, whichever occurs first, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006.
(iii) The repetitive interval specified in paragraph (f)(1)(ii) of this AD is valid until the threshold of Airbus A300-600 Airworthiness Limitation Items (ALI) Task 571006-02-1 is reached. After reaching this threshold, the ultrasonic inspection is to be done according to Task 571006-02-1, “Special detailed inspection (Ultrasonic) of wing junction at rib 1 horizontal flange of lower T section, between FR40 and FR47 inboard side, LH/RH,” of Airbus A300-600 Airworthiness Limitation Items Document AI/SE-M2/95A.0502/06, Issue 11, dated April 2006.
(2) Action No. 2, for the outer wing box:
(i) At the later of the times in paragraphs (f)(2)(i)(A) and (f)(2)(i)(B) of this AD: Do an external ultrasonic inspection for cracking of the taperlocks fasteners of the outer wing box, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006. If any crack is detected: Before further flight, contact Airbus for repair instructions, and repair.
(A) Before the accumulation of 15,200 total flight cycles or 31,700 total flight hours, whichever occurs first.
(B) Within 3 months after the effective date of this AD.
(ii) Repeat the inspection thereafter at intervals not to exceed 3,700 flight cycles or 7,700 flight hours, whichever occurs first, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006.
(iii) The repetitive interval specified in paragraph (f)(2)(ii) of this AD is valid until reaching the threshold of Airbus A300-600 Airworthiness Limitation Items (ALI) Task 571022-01-2, “Special detailed inspection (Ultrasonic) of wing-fuselage lower skin splice at rib 1 (wing side).” After reaching this threshold, the ultrasonic inspection is to be done according to Task 571022-01-2 of Airbus A300-600 Airworthiness Limitation Items Document AI/SE-M2/95A.0502/06, Issue 11, dated April 2006.
(3) Action No. 3, for the outer wing box:
(i) At the later of the times in paragraphs (f)(3)(i)(A) and (f)(3)(i)(B) of this AD: Do an internal x-ray inspection for cracking of the taperlocks fasteners of the outer wing box, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006. If any crack is detected: Before further flight, contact Airbus for repair instructions, and repair.
(A) Before the accumulation of 20,900 total flight cycles or 43,400 total flight hours, whichever occurs first.
(B) Within 3 months after the effective date of this AD.
(ii) Repeat the inspection thereafter at intervals not to exceed 1,800 flight cycles or 3,700 flight hours, whichever occurs first, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A300-53-6154, excluding Appendix 01, dated June 20, 2006.
(iii) The repetitive interval specified in paragraph (f)(3)(ii) of this AD is valid until reaching the threshold of Airbus A300-600 Airworthiness Limitation Items (ALI) Task 571022-02-2, “Special detailed inspection (XRAY) of wing-fuselage lower skin splice at rib 1 (wing side).” After reaching this threshold, the x-ray inspection is to be done according to Task 571022-02-2 of Airbus A300-600 Airworthiness Limitation Items Document AI/SE-M2/95A.0502/06, Issue 11, dated April 2006.
Note: 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.
