What the NTSB Record States About Cause: Factual Summary of DCA25MA108
The NTSB opens its conclusions with the words, "The National Transportation Safety Board determines the probable cause(s) of this accident to be:" What follows is quoted from the final report, attributed to the NTSB and published February 17, 2026. This page adds no cause of its own.
The NTSB states the probable cause as: "The Federal Aviation Administration's (FAA) placement of a helicopter route in close proximity to a runway approach path; their failure to regularly review and evaluate helicopter routes and available data, and their failure to act on recommendations to mitigate the risk of a midair collision near Ronald Reagan Washington National Airport (DCA); as well as the air traffic system's overreliance on visual separation in order to promote efficient traffic flow without consideration for the limitations of the see-and-avoid concept. Also causal was the lack of effective pilot-applied visual separation by the helicopter crew, which resulted in a midair collision."
The report continues that "Additional causal factors were the tower team's loss of situation awareness and degraded performance due to the high workload of the combined helicopter and local control positions and the absence of a risk assessment process to identify and mitigate real-time operational risk factors," and that "Also causal was the Army's failure to ensure pilots were aware of the effects of error tolerances on barometric altimeters in their helicopters, which resulted in the crew flying above the maximum published helicopter route altitude."
The NTSB then lists contributing factors, including the limitations of the traffic awareness and collision alerting systems on both aircraft; "an unsustainable airport arrival rate, increasing traffic volume with a changing fleet mix, and airline scheduling practices at DCA"; the Army's lack of a fully implemented safety management system; the FAA's failure to implement previous NTSB recommendations, "including Automatic Dependent Surveillance–Broadcast In"; and "the absence of effective data sharing and analysis among the FAA, aircraft operators, and other relevant organizations."
Alongside that narrative, the report attaches short coded findings to both aircraft, and several echo the themes above, such as "Task overload - ATC personnel," "Traffic congestion - Contributed to outcome" and "Dark - Contributed to outcome."
For a family, the stake is that the NTSB names several organizations and conditions, not a single cause. These are safety conclusions, not a court's findings of legal fault. A family reading them may ask which of the named organizations and practices relate to their loss, and an attorney can help explain how the legal questions differ from the safety ones.
