Summary
We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed 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:
Due to several crack findings in the area of wing centre box lower aft corner at FR47, this area of structure has been subjected to accomplishment of several inspection Service Bulletins rendered mandatory in accordance with Airworthiness Limitation Items requirement for A300 aircraft and Airworthiness Directive (AD) F- 2004-159 for A300-600 aircraft [which corresponds to FAA AD 2005-23- 08]. This AD is published * * * in order to control or correct the development of cracks, which could affect the structural integrity of the aircraft.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
