Airworthiness Directive · Amendment 39-18828 · Fuselage
Airbus Airplanes
This AD applies to all Airbus Model A300 B4-603, B4-620, and B4-622 airplanes; Model A300 B4-605R and A300 B4-622R airplanes; and Model A300 C4-605R Variant F airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-603, B4-620, and B4-622 airplanes; Model A300 B4- 605R and A300 B4-622R airplanes; and Model A300 C4-605R Variant F airplanes. This AD was prompted by an in-service detection of cracks in the fuselage skin lap joints. This AD requires an ultrasonic inspection of certain skin lap joints, and repair if necessary. We are issuing this AD to address the unsafe condition on these products.
Before 29,500 flight cycles since the first flight of the airplane, or within 2,000 flight cycles after the effective date of this AD, whichever occurs later, do an ultrasonic inspection for cracks of the skin lap joint below STR 28 at FR 72 to FR 76 and do all applicable repairs before further flight, in accordance with the Accomplishment Instruction of Airbus Service Bulletin A300-53-6184, dated November 12, 2015, except as required by paragraph (h) of this AD. Repeat the ultrasonic inspection thereafter at intervals not to exceed 5,400 flight cycles.
Where Airbus Service Bulletin A300-53-6184, dated November 12, 2015, specifies to contact Airbus for repair instructions, and specifies that action as “RC” (Required for Compliance), this AD requires repair before further flight using a method approved in accordance with the procedures specified in paragraph (j) of this AD.
Although Airbus Service Bulletin A300-53-6184, dated November 12, 2015, specifies to submit certain information to the manufacturer, and specifies that action as RC, this AD does not include that requirement.
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.
