One year after Reagan National midair collision, investigators detail failures and permanent airspace safety changes

A deadly collision near Reagan National

On Jan. 29, 2025, a U.S. Army UH-60 Black Hawk helicopter and an American Airlines regional passenger jet collided near Ronald Reagan Washington National Airport and fell into the Potomac River. All 67 people aboard the two aircraft were killed, making it the deadliest U.S. aviation disaster since 2001.

As the one-year mark approaches on Jan. 29, 2026, federal investigators are preparing to detail contributing factors and outline safety recommendations intended to prevent a similar event in the tightly constrained airspace surrounding the nation’s capital.

What investigators have established so far

Investigators have identified multiple, overlapping issues rather than a single failure. Findings disclosed over the past year indicate the Black Hawk was flying above the maximum altitude authorized for the helicopter route as it neared the airport, reducing vertical separation from arriving aircraft. Investigators have also examined conflicting altitude information tied to the helicopter’s instruments, including indications the altimeter data used by the crew may have been unreliable.

The sequence leading to impact also involved air traffic control clearances that relied on “visual separation,” a procedure under which pilots maintain separation from another aircraft they report seeing. Investigators have indicated that communications issues occurred in the final moments, including transmissions that may not have been fully received in the helicopter cockpit.

The investigation has focused on route design, cockpit instrumentation, communication clarity, and operating practices that allowed aircraft to converge in close proximity.

Key moments in the approach

• Late evening Jan. 29, 2025: the passenger jet begins descending toward Reagan National.

• Shortly before the crash: controllers request a runway change for the jet, while the Army helicopter proceeds along a route over the river.

• Minutes later: the helicopter crew reports the jet in sight and is cleared to use visual separation; the aircraft collide seconds later.

Regulatory and operational changes implemented

Following the crash, the Federal Aviation Administration put in place restrictions intended to separate helicopter and fixed-wing traffic around Reagan National. Those measures have since been formalized into permanent rules and procedures that include barring controllers from using visual separation in defined airspace near the airport and requiring consistent position broadcasting by military aircraft using ADS-B Out, with limited exceptions.

In addition to permanent restrictions, helicopter routes and charted procedures around Reagan National have been revised over time to increase distance from arriving and departing airline traffic, with updated zones and transitions designed to provide greater separation.

Community impact and continuing scrutiny

The passenger manifest included members of the U.S. figure skating community returning from a development camp held in conjunction with the 2025 U.S. Figure Skating Championships in Wichita, Kansas. The loss intensified public attention on how mixed helicopter and airline operations are managed in the National Capital Region.

Investigators are expected to continue pressing for changes that address airspace design, aircraft equipment use, and operating procedures—areas that remain under scrutiny as the region balances routine military, medical, law enforcement, and commercial aviation activity.
