Final rule.

This action extends the prohibition against certain flight operations in specified areas of the Sanaa Flight Information Region (FIR) (OYSC) 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 three years, from January 7, 2025, until January 7, 2028. The FAA finds this action necessary to address significant, unacceptable safety-of-flight risks to U.S. civil aviation operations in the specified areas of the Sanaa FIR (OYSC) stemming from heightened regional tensions associated with Houthi weapons employment and operational activities. Most recently, Houthi forces have engaged in increased weapons employment and operational activities related to the Israel-Gaza Conflict, leading in some cases to air defense responses. The FAA also takes into account the Houthis' recent history of having conducted long-range attacks emanating from the Sanaa FIR (OYSC) in other directions, notably against Saudi Arabia and the United Arab Emirates (UAE) in 2022. The FAA also republishes the approval process and exemption information for this Special Federal Aviation Regulation (SFAR), consistent with other recently published flight prohibition SFARs.
