## Abstract

This action reissues a prohibition of certain flight operations in the Damascus (OSTT) Flight Information Region (FIR) by all U.S. air carriers; U.S. commercial operators; persons exercising the privileges of an airman certificate issued by the FAA, except such persons operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except where the operator is a foreign air carrier. The FAA finds that this action is necessary to safeguard against continuing hazards to persons and aircraft engaged in such flight operations.
