Extension of the Prohibition Against Certain Flights in Specified Areas of the Sanaa Flight Information Region (FIR) (OYSC)

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. The FAA finds this action necessary to address the continued hazards to persons and aircraft engaged in such flight operations from the ongoing fighting and instability in Yemen, as well as terrorist and militant activity. The FAA also republishes, with minor revisions, the approval process and exemption information for this flight prohibition Special Federal Aviation Regulation (SFAR); makes a technical correction to the SFAR to show that operations on jet route M999 are permitted; makes editorial changes to this SFAR to clarify prohibited and permitted operations; makes a minor editorial change to the title of the rule; and makes other minor revisions for consistency with other recently published flight prohibition SFARs.
