The FAA has issued an interim final rule permanently restricting the operation of helicopters and powered lift in the vertical-lift flight mode in a defined area of airspace near Ronald Reagan Washington National Airport (KDCA). This formalizes measures temporarily enacted after the fatal Jan. 29, 2025 midair collision over the Potomac River.
Published in the Federal Register on Friday, the rule adds a new subpart to FAR Part 93 and prohibits helicopters and powered-lift aircraft operating in vertical-lift mode from flying in a designated area between the Memorial Bridge, Hains Point, and the Wilson Bridge unless conducting an essential operation. According to the rule, the restrictions are intended “to mitigate the potential for midair collisions resulting from insufficient separation between fixed-wing aircraft operating to or from KDCA and helicopters or powered-lift operating in the vertical-lift flight mode near KDCA.”
