## Abstract

The FAA is adopting a new airworthiness directive (AD) for all EMBRAER Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This AD requires modifying electrical harnesses located at the left- and right-hand wing roots; and re-routing and modifying the harness of the right-hand outboard flap actuator. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent chafed electrical harnesses, which could result in a potential source of ignition for fuel vapors near a fuel tank and consequent fire or fuel tank explosion.
