## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-120, -120ER, -120FC, -120QC, and -120RT airplanes in operation. This AD requires replacing the protective tubes and conduits of the wiring harnesses of the refueling vent and pilot valves with non-conductive hoses; modifying the harness wiring and supports; and rerouting the harnesses to prevent interference with adjacent strobe light connectors; as applicable. This AD results from a fuel system review conducted by the manufacturer. We are issuing this AD to prevent a potential source of ignition near a fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion.
