## Abstract

We are adopting a new airworthiness directive (AD) for XtremeAir GmbH Model XA42 airplanes equipped with an engine mount part number XA42-7120-151. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the diagonal strut of the engine mount frame. We are issuing this AD to require actions to address the unsafe condition on these products.
