Air travelers across the Washington, D.C. metropolitan area experienced significant disruptions on Friday, March 13, 2026, following an equipment malfunction at a critical air traffic control facility. The incident led to ground stops at multiple airports, including Ronald Reagan Washington National Airport (DCA), Washington Dulles International Airport (IAD), and Baltimore/Washington International Thurgood Marshall Airport (BWI).
The Federal Aviation Administration (FAA) confirmed the ground stops were initiated after a chemical odor was detected at the Potomac TRACON (Terminal Radar Approach Control) center in Warrenton, Virginia. This facility is responsible for managing airspace for a wide region, encompassing the Baltimore-Washington and Richmond-Charlottesville areas, including major hubs like Andrews Air Force Base and Richmond International Airport.
Cause of Disruption and Response
Transportation Secretary Sean Duffy announced via social media that the chemical smell originated from an overheated circuit board within the TRACON facility. Emergency services, including HAZMAT teams, responded to the scene to assess the situation.
More than 30 FAA personnel underwent medical evaluations as a precautionary measure, though all were subsequently cleared to return to duty once the facility was deemed safe. The affected circuit board was promptly replaced, allowing the ground stops to be lifted after approximately three hours.
Widespread Travel Delays and Cancellations
Despite the resolution of the technical issue, the impact on air travel persisted throughout the evening. Initial delays at Baltimore/Washington International exceeded two and a half hours, while Dulles International saw delays of up to three hours. Ronald Reagan National Airport experienced the most significant impact, with delays extending beyond three and a half hours.
Flight tracking data indicated a rising number of cancellations, particularly at Reagan National, which reported 136 cancellations and over 300 delays by Friday evening. Dulles and Baltimore airports each recorded more than 40 cancellations and over 200 delays. These disruptions were exacerbated as flight crews approached their maximum working hours, leading to further operational challenges.
Passenger Experience and Communication
Passengers at the affected airports faced prolonged waits, with many reporting limited information from airline staff. Travelers often relied on personal mobile devices for updates regarding their flight status. The incident highlighted the cascading effects of air traffic control issues on regional and national air travel networks, underscoring the interconnectedness of aviation infrastructure.
Broader Implications for Air Travel
Such incidents, while often resolved quickly, can have significant economic repercussions due to lost productivity, missed connections, and the operational costs incurred by airlines. They also underscore the critical importance of robust infrastructure and rapid response protocols within the national airspace system. The FAA continuously monitors and upgrades its systems to prevent such occurrences and ensure the safety and efficiency of air travel.
