## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-135 and EMB'145 series airplanes, that requires replacement of certain brake control units (BCU) with new units. The actions specified by this AD are intended to prevent uncommanded application of 50 percent braking in one pair of wheels, which could result in the airplane skidding off the runway. This action is intended to address the identified unsafe condition.
