## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-120 series airplanes, that requires inspections of certain components, and corrective action, if necessary. The actions specified by this AD are intended to prevent deterioration and deformation of the mass-balance weights of the aileron, which could affect the surface balance of the aileron and result in loss of aileron control and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
