## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to all EMBRAER Model EMB-120 series airplanes. This action requires revising the Airplane Flight Manual, installing a placard on the main instrument panel, and removing the "LIGHT-HEAVY" inflation switch of the leading edge deicing boots. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This action is intended to ensure that the flight crew is provided with accurate indications of the severity of ice accretion and appropriate procedures and actions to prevent reduced controllability of the aircraft due to accretion of ice on the airplane.
