## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Dassault Model Mystere-Falcon 50 series airplanes, that requires one-time detailed inspections for structural discrepancies of various fuselage attachments; and corrective actions, if necessary, to restore the structure to the original design specifications. This action is necessary to prevent early fatigue, corrosion, or fretting, which could result in structural failure of major components of the airplane and reduced structural integrity of the airplane. This action is intended to address the identified unsafe condition.
