Investigation Summary
The accident highlighted a systemic failure in the management of the Special Flight Rules Area (SFRA) around Washington, D.C. The helicopter, callsign PAT25, was flying 'Route 4' along the Potomac River, a path that intersected the final approach for DCA's runway 33. On the night of the accident, a single controller was managing both local airport traffic and the helicopter transition routes, a combination of duties that led to a loss of situational awareness. The Black Hawk was flying at approximately 278 feet radio altitude, exceeding the published route maximum of 200 feet due to barometric altimeter error tolerances that the crew had not been adequately trained to account for. Simultaneously, the CRJ-700 was performing a circling maneuver to runway 33, placing the two aircraft on a collision course. Although the CRJ-700 received a TCAS Traffic Advisory 19 seconds before impact, the Black Hawk's ADS-B Out was not broadcasting, which limited the effectiveness of the airliner's collision avoidance system. The aircraft collided approximately 0.5 miles southeast of the airport, with the helicopter's rotor system striking the airliner's fuselage.
Final Conclusions
The NTSB concluded that the primary cause was the FAA's design of helicopter routes in close proximity to runway approach paths without adequate risk mitigation. The investigation found that the FAA had failed to act on previous recommendations to deconflict this airspace. Causal factors included the helicopter crew's failure to maintain visual separation, the ATC tower team's degraded performance under high workload, and the U.S. Army's failure to ensure pilots understood altimeter error tolerances. The board also noted that the 'see-and-avoid' concept is insufficient for high-density, complex terminal environments.

Systems & Failure Modes
TCAS I
The CRJ-700 was equipped with TCAS I, which provided traffic advisories but not resolution advisories (evasive maneuvers).
ADS-B Out
The helicopter's ADS-B Out system was either malfunctioning or turned off, preventing the airliner from receiving precise position data.
Barometric Altimeter
Error tolerances in the helicopter's altimeter, combined with external stores support system configuration, contributed to the crew flying higher than intended.
Interesting Facts
- 01The Black Hawk helicopter was not broadcasting ADS-B data at the time of the collision.
- 02The helicopter was flying at 278 feet, while the published maximum for Route 4 was 200 feet.
- 03A single controller was managing both the Local and Helicopter control positions, which was not normal for that time of day.
- 04The NTSB issued 74 findings and 50 safety recommendations following the investigation.
- 05The collision occurred at night, though visibility was reported as unlimited.
Safety Actions & Advisories
Helicopter Route Restrictions
The FAA prohibited operations on Helicopter Route 4 between Hains Point and the Wilson Bridge when DCA runways 15 and 33 are in use.
ADS-B Mandate
The NTSB recommended requiring all aircraft operating in ADS-B Out airspace to also be equipped with ADS-B In with cockpit traffic displays.
ATC Workload Management
New recommendations were made to implement time-on-position limitations for supervisory air traffic personnel and to reassess DCA's arrival rates.
