The FAA will initiate a classified threat assessment, which will be coordinated with Intelligence Community partners, to support the agency’s determination of whether circumstances warrant the extension of the prohibition against certain flight operations in the territory and airspace of Libya by all: U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except when such persons are operating U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when the operator of such aircraft is a foreign air carrier, for an additional time to be determined. The FAA expects the extension of the flight prohibition will be necessary to address a continuing hazard to persons and aircraft engaged in such flight operations. The threat assessment will also support the agency’s determination of whether any modifications to the parameters of the flight prohibition, if extended, would be appropriate at this time, based on the risks to the safety of U.S. civil aviation.
