FAR 91.1609 — Damascus FIR Prohibition
FAR 91.1609 (SFAR 114) prohibits U.S. operators and FAA airmen from flying in the Damascus FIR (OSTT). Learn exceptions, emergency deviations, and reporting.
FAR 91.1609 is Special Federal Aviation Regulation (SFAR) No. 114, which prohibits flight operations in the Damascus Flight Information Region (FIR), ICAO identifier OSTT (the airspace over Syria). It exists because the security environment in Syria poses serious risks to civil aviation.
The rule applies to:
- All U.S. air carriers and U.S. commercial operators
- All persons exercising the privileges of an FAA airman certificate (unless flying U.S.-registered aircraft for a foreign air carrier)
- All operators of U.S.-registered civil aircraft (unless the operator is a foreign air carrier)
There are two ways to legally operate in the Damascus FIR:
- Under a contract, grant, or cooperative agreement with a U.S. government department or agency, with FAA approval, or under an FAA-issued exemption.
- In an emergency requiring immediate action for the safety of flight — the pilot in command may deviate as needed.
If you deviate due to an emergency, non-Part 119/121/125/135 operators must file a written report with the responsible Flight Standards office within 10 business days. The SFAR is currently set to expire December 30, 2028.
