## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050, 100, 200, 300, 400, 500, 600, and 700 series airplanes, and Model F28 Mark 0070, 0100, 1000, 2000, 3000, and 4000 series airplanes, that requires a one-time functional test to verify correct installation of the shoulder harnesses of the pilot's and co-pilot's seats and, if necessary, replacement of the shoulder harness assembly with a new or serviceable shoulder harness assembly. 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 failure of the shoulder harness, which could result in injury to the flight crew during extremely turbulent flight conditions or during emergency landing or stopping conditions.
