FAA Permanently Limits Helicopter Flights Near Reagan Airport

The Federal Aviation Administration (FAA) has permanently restricted helicopter and powered-lift operations in airspace around Ronald Reagan Washington National Airport (DCA), formalizing emergency measures initially imposed after a fatal midair collision in January 2025 and fully implementing urgent safety recommendations from the National Transportation Safety Board (NTSB).

The action was announced via an interim final rule published in the Federal Register, adding a new subpart to Federal Aviation Regulation Part 93. The rule permanently prohibits helicopters and powered-lift aircraft in vertical-lift mode from flying in a defined area between the Memorial Bridge, Hains Point, and the Wilson Bridge, unless the flight qualifies as an essential operation. The FAA said the restrictions are intended “to mitigate the potential for midair collisions resulting from insufficient separation between fixed-wing aircraft operating to or from DCA and helicopters or powered-lift aircraft operating in vertical-lift mode.”

US Transportation Secretary Sean Duffy said the decision reflects the government’s response to the January 2025 crash involving a commercial airliner and a military helicopter near the airport. “After that horrific night in January, this administration made a commitment to do everything necessary to secure the skies over our nation’s capital and ensure that a tragedy like this never happens again,” Duffy said.

The interim final rule codifies measures previously enacted through temporary flight restrictions following the Jan. 29, 2025 collision over the Potomac River. The crash involved a US Army Sikorsky UH-60L Black Hawk helicopter and American Airlines Flight 5342, a regional jet operated by PSA Airlines. All 67 people aboard both aircraft were killed.

Investigators reported that the Black Hawk was flying along Washington Route 4, a helicopter corridor used for decades, at approximately 300 feet, exceeding the established 200-foot limit. The passenger jet was on approach to Runway 33, a less frequently used runway whose flight path intersects Route 4. The NTSB noted a history of close-proximity events between helicopters and fixed-wing aircraft in Reagan National airspace.

The FAA said the rule fully implements an urgent March 2025 NTSB recommendation, which called for permanently prohibiting helicopter operations on Route 4 when Runways 15 and 33 are active. FAA Administrator Bryan Bedford said, “We acted immediately after the January 2025 collision to reduce risks and are now making those measures permanent. This ensures improvements remain in place, and we continue working with the NTSB to prevent future accidents.”

Essential operations are narrowly defined and include lifesaving medical missions, active law enforcement, national security operations, continuity-of-government flights, and transport of the president or vice president. Routine training, proficiency checks, and nonessential personnel transport are excluded. The FAA emphasized that “essential helicopter operations in this area should be exceedingly rare.”

When an essential helicopter operation must occur within the restricted airspace, air traffic control will manage fixed-wing aircraft movements to reduce collision risk. The agency said these procedures are designed to provide additional separation during the limited circumstances in which helicopter access is permitted.

The FAA also highlighted additional post-crash safety measures, including:

• Eliminating mixed helicopter and fixed-wing traffic near the airport.

• Suspending departures from the Pentagon helipad until FAA and Department of Department of War procedures were updated.

• Removing visual separation requirements within a five-nautical-mile radius.

• Updating helicopter route charts in October 2025, eliminating Route 4 north of the Wilson Bridge and revising routes near Reagan National, Washington Dulles, and Baltimore/Washington International Airports.
