## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Fokker Model F27 Mark 050 series airplanes. This action requires a one-time inspection to detect cracking of the fuselage between stations 15375 and 16275, at the skin splice above the cabin windows; and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to detect and correct such cracking, which could result in depressurization of the cabin and reduced structural integrity of the airplane fuselage.
