SUMMARY: We are adopting a new airworthiness
directive (AD) for the products listed above. This AD results from
mandatory continuing airworthiness information (MCAI) issued by the
aviation authority of another country to identify and correct an
unsafe condition on an aviation product. The MCAI describes the

This AD requires actions that are intended to address the
unsafe condition described in the MCAI.
