We are adopting a new airworthiness directive (AD) for the products listed above. 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:
Unless already done, do the following actions.
(1) For Model Mystère-Falcon 900 airplanes: Do the actions specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD.
