## 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 the nose landing gear wheel nuts and associated inner and outer seals; and reidentification of the landing gear strut. This action is necessary to prevent separation of the wheels from the nose landing gear due to the failure of the outer wheel bearings, and consequent loss of control of the airplane during takeoff and landing. This action is intended to address the identified unsafe condition.
