Abstract
We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, -300F, and -400ER series airplanes. This AD requires an inspection to determine if certain motor operated valve actuators for the fuel tanks are installed, and related investigative and corrective actions if necessary. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent an ignition source inside the fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
