Airworthiness Directives; Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fatigue damage with a crack propagation through the fastener line of the wing shroud box bottom panel, resulting in panel detachment and potential injuries to persons on the ground. We are issuing this AD to require actions to correct the unsafe condition on these products.
