## Abstract

This action extends the 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 a U.S. airman certificate, except when such persons are operating a U.S.-registered aircraft for a foreign air carrier; and operators of U.S.-registered civil aircraft, except when such operators are foreign air carriers. The FAA finds that this action continues to be necessary to address a potential hazard to persons and aircraft engaged in such flight operations.
