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 upper frame of the firewall for the auxiliary power unit (APU). This AD results from the discovery of a hole in the upper frame of the firewall for the APU. We are issuing this AD to ensure that the APU compartment is isolated from the rest of the airplane in the event of an APU fire. If the APU compartment is not isolated, smoke could enter the passenger cabin in the event of an APU fire.
