Airworthiness Directives; Aerospatiale Model ATR72-212A Series Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Aerospatiale Model ATR72- 212A series airplanes. This proposal would require installation of bushings on the lower attachment fittings of the flap support beam. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed 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.
