## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to all EMBRAER Model EMB-135 and -145 series airplanes, that currently requires repetitive inspections of the engine thrust reverser stow/transit switches, and corrective action, if necessary. This amendment continues to require the existing requirements and identifies the installation of certain new transit switches, which constitutes terminating action for the repetitive inspections. This action also changes the applicability. The actions specified by this AD are intended to prevent erroneous signals in the Engine Indicating and Crew Alerting System (EICAS) caused by internal corrosion of the thrust reverser stow/transit switches, which could result in uncommanded loss of engine power in flight, or unnecessary aborted takeoffs on the ground.
