Airbus Model A300 B2 and B4 Series Airplanes, and Model A300 B4-600, B4-600R, and F4-600R (Collectively Called A300-600) Series Airplanes
Superseded. A later AD replaced this one: AD 2001-20-06. Comply with the one in force.
The following airplanes, certificated in any category: --Model A300 B2 and B4 series airplanes, except those modified by Airbus Modification 11932 (reference Airbus Service Bulletin A300- 57-0235, Revision 01, including Appendix 01, dated February 1, 1999; or earlier version); and --Model A300 B4-600, B4-600R, and F4-600R (collectively called A300- 600) series airplanes; manufacturer serial numbers (MSNs) up to and including MSN 787; except those modified by Airbus Modification 11932 (reference Airbus Service Bulletin A300-57-6088, Revision 01, including Appendix 01, dated February 1, 1999; or earlier version).
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A300 B2 and B4 series airplanes, and certain Model A300 B4-600, B4-600R, and F4-600R (collectively called A300-600) series airplanes. This action requires a one-time inspection to detect cracks in gear rib 5 (left and right) of the main landing gear (MLG) attachment fittings at the lower flange and vertical web, and repair if necessary. This action is necessary to detect and correct fatigue cracking of the MLG attachment fittings, which could result in reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
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.
