## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB SF340A and SAAB 340B series airplanes, that requires a one-time visual inspection of the main landing gear (MLG) brake assemblies to determine the brake configuration, and reconfiguration, 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 prevent an incorrect brake combination configuration of the MLG, and consequent reduced controllability of the airplane during take-off and landing.
