## Abstract

This amendment adopts a new airworthiness directive (AD) that applies to EXTRA Flugzeugbau GmbH Models EA-300 and EA-300/S airplanes. This AD requires inspecting the upper longeron cutout bridge for cracks, repairing any cracks found, and modifying this area. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by this AD are intended to prevent structural damage to the fuselage caused by cracks in the upper longeron cutout bridge, which, if not detected and corrected, could result in loss of control of the airplane.
