Airworthiness Directives; Aerospatiale Model ATR42-200, -300, and -320 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR42-200, -300, and -320 series airplanes, that requires an inspection to detect corrosion of the rear spars of the wings, and corrective actions, if necessary. 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 detect and correct possible corrosion on the rear spars of the wings, which could result in reduced structural integrity of the wings.
