e Reason This AD was prompted by mandatory continuing airworthiness information MCAI
originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI
identifies the unsafe condition as insufficient separation of ground terminations for individual power sources and static grounds.
The FAA is issuing this AD to detect and correct ground terminations with insufficient separation, which could lead to loss of primary and secondary power sources if the ground connection fails and consequent simultaneous loss of multiple airplane systems.

RIN 2120AL69

Extension of the Prohibition Against Certain Flights in Specified Areas of the Sanaa Flight Information Region FIR OYSC
Federal Aviation Administration FAA, Department of Transportation DOT.
ACTION: Final rule.
AGENCY:

This action extends the Special Federal Aviation Regulation SFAR prohibiting certain flights in the 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 hazards to persons and aircraft engaged in such flight operations due to significant, continuing safety-of-flight risks to U.S.
civil aviation operations in that airspace associated with the ongoing conflict between the Saudi Arabian-led Coalition and Iranian-aligned Houthi forces. The FAA extends the expiration date of this SFAR from January 7, 2022, until January 7, 2025. Additionally, the FAA republishes the approval process and exemption information for this SFAR, consistent with other recently published flight prohibition SFARs.
