## Abstract

This amendment adopts a new airworthiness directive (AD) that is applicable to all EMBRAER Model EMB-135 and -145 series airplanes. This action requires repetitive inspections of the engine thrust reverser stow/transit switches, and corrective action, if necessary. This action is necessary 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. This action is intended to address the identified unsafe condition.
