## Abstract

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 aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as fuel manifold leakage that could result in engine fire, in-flight shutdown or damage to the airframe. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
