Airworthiness Directives; Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120, -120ER, -120FC, -120QC, and -120RT Airplanes

الملخص

The FAA proposes to adopt a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes. This proposed AD would require 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 proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing 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.
