FAA Finalizes Permanent Rules to Secure Reagan National Airspace After Deadly Mid-Air Collision
Aviation News Editor & Industry Analyst delivering clear coverage for a worldwide audience.
The FAA made permanent new safety rules for Washington D.C.'s Reagan National Airport airspace, requiring military ADS-B Out and ending visual separation after the deadly mid-air collision.
Key Takeaways
- •The FAA made permanent the temporary rules imposed after the January 29, 2025, mid-air collision near DCA, formalizing the final rule on Friday.
- •New regulations mandate all military aircraft use ADS-B Out for location broadcasting and prohibit air traffic controllers from using visual separation within five miles of Reagan National Airport.
- •The collision, which killed 67 people, occurred in an airspace that the NTSB reported had over 15,000 close proximity events between planes and helicopters from late 2021 to late 2024.
- •The permanent rules eliminate mixed helicopter and fixed-wing traffic in certain critical approach areas to enhance commercial aviation safety.
The Federal Aviation Administration (FAA) has announced the permanent adoption of critical safety rules for the crowded airspace surrounding Ronald Reagan Washington National Airport (DCA). The final rule takes effect on Friday, formalizing temporary restrictions put in place following the tragic mid-air collision last year. This move is a direct response to the accident involving an American Airlines jet and an Army helicopter.
Enhancing Airspace Safety
Transportation Secretary Sean Duffy emphasized the administration’s commitment. He stated the goal is to secure the skies over the nation’s capital. The new permanent rules focus on eliminating key risk factors identified in the wake of the disaster. The FAA's decision aims to prevent a similar tragedy from ever happening again.
Key Regulatory Changes
The final rule introduces several mandatory changes to air traffic control and aircraft operations near DCA. These protocols are designed to increase separation and enhance aircraft visibility. The changes directly address issues highlighted by the National Transportation Safety Board (NTSB) investigation.
- Mandatory ADS-B Out: All military aircraft must now broadcast their location using Automatic Dependent Surveillance-Broadcast Out (ADS-B Out) systems. This equipment was often not used by military aircraft before the crash.
- Eliminating Visual Separation: Air traffic controllers are prohibited from relying on visual separation for aircraft within five miles (eight kilometers) of Reagan National Airport. This ensures controllers maintain positive radar separation.
- Separation of Traffic: The FAA has taken steps to ensure that helicopters and fixed-wing airplanes no longer share the same airspace around DCA. This includes permanently closing helicopter Route 4 between Hains Point and the Wilson Bridge.
- Restricted Helicopter Operations: Certain non-essential helicopter operations are now permanently restricted near DCA. This is especially true when Runways 15 and 33 are in use.
The Collision Context
The permanent rules follow the collision on January 29, 2025, over the Potomac River. An American Airlines Flight 5342, a Bombardier CRJ700, was on approach to DCA. It struck a U.S. Army Sikorsky UH-60 Black Hawk helicopter. All 67 people aboard both aircraft were killed in the crash. It was the deadliest U.S. air disaster since 2001. The NTSB investigation revealed a history of safety concerns in the area. Data showed 15,214 close proximity events between planes and helicopters between October 2021 and December 2024. Of these, 85 were classified as very close, with less than 200 feet of vertical separation. The NTSB plans to hold a hearing next Tuesday to detail its full findings and recommendations.
Impact on Aviation Operations
For commercial airlines like American Airlines, the new rules provide a higher degree of safety assurance during approach into DCA. The elimination of visual separation removes a variable that contributed to the accident. For the military, the mandate to use ADS-B Out requires procedural and equipment compliance. This ensures their aircraft are fully visible to air traffic control and other transponder-equipped aircraft. The changes underscore the ongoing need for rigorous airspace management in high-density areas. FAA Administrator Bryan Bedford stated that these safety procedures will not be rolled back. The new regulations are expected to serve as a model for other congested terminal areas.
