Abstract
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR72-212A series airplanes, that requires installation of bushings on the lower attachment fittings of the flap support beam. 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 rupture of the lower attachment fittings of the flap support beam due to fatigue, and consequent damage to the flaps; these conditions could result in reduced controllability of the airplane.
