## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain EMBRAER Model EMB-135 airplanes, and Model EMB-145, -145ER, - 145MR, -145LR, -145XR, -145MP, and -145EP airplanes. This AD requires modification of the logic of the steering system of the nose landing gear (NLG) wheel. This AD results from reports of the loss of directional control of the airplane on the ground after an internal failure of the NLG wheel steering system. We are issuing this AD to prevent failure of the NLG wheel steering system, which could result in reduced controllability of the airplane.
