## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain EMBRAER Model EMB-135 and EMB-145 series airplanes. This proposal would require replacement of certain brake control units (BCU) with new units. This action is necessary 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.
