Airworthiness Directives; Airbus Model A330 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 an incomplete discharge of the extinguishing agent in the fire zone, which could lead, in the worst case, in combination with an engine fire, to a temporary uncontrolled engine fire. We are issuing this AD to require actions to correct the unsafe condition on these products.
