## Summary

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain EXTRA Flugzeugbau GmbH (EXTRA) Models EA-300 and EA-300/S airplanes. The proposed AD would require inspecting the upper longeron cutout bridge for cracks, repairing any cracks found, and modifying this area. The proposed AD is the result of mandatory continued airworthiness information (MCAI) issued by the airworthiness authority for Germany. The actions specified by the proposed 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.
