Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain CASA Model CN-235 series airplanes, that requires modification of the forward beam of the vertical stabilizer by the installation of a structural reinforcement plate. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent in-flight structural deformation or failure of the vertical stabilizer, resulting in reduced controllability of the airplane.
