## Abstract

This action extends the prohibition against certain flight operations in the Damascus Flight Information Region (FIR) (OSTT) 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 where the operator of such aircraft is a foreign air carrier. The FAA finds this action to be necessary to address a potential hazard to persons and aircraft engaged in such flight operations. This action also includes minor editorial changes to this Special Federal Aviation Regulation (SFAR), consistent with other recently published flight prohibition SFARs.
