## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB SF340A and SAAB 340B series airplanes, that requires modification of the insulation pads in the lower side of the fuselage at the wing aft area. 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 loose insulation from interfering with an aileron control cable, which could result in reduced aileron control.
