AD FAA-2011-0570

We are adopting a new airworthiness directive (AD) for all Airbus Model A300 series airplanes; Model A310 series airplanes; and Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model C4- 605R Variant F airplanes (collectively called A300-600 series airplanes). 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: * * * * * A recent analysis conducted by the manufacturer showed a particular risk for explosive failure of the * * * hydraulic accumulator. This condition, if not detected and corrected, might, for some aeroplane installations, lead to damage to all three hydraulic circuits, possibly resulting in loss of control of the aeroplane or could, for certain other aeroplane installations, lead to an undetected fire in the wheel bay. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
