Ground stops were implemented at multiple airports in the Washington D.C. area and Virginia on Friday afternoon. This action followed the detection of a chemical odor at the Federal Aviation Administration's (FAA) Potomac Terminal Radar Approach Control (TRACON) facility in Warrenton, Virginia. The ground stops were lifted by Friday evening, though flight delays persisted through the night and into the following day.
Ground stops affected multiple airports in the Washington D.C. area and Virginia on Friday afternoon after a chemical odor was detected at the FAA's Potomac TRACON facility. The issue was later identified as an overheated circuit board, and while the ground stops were lifted by evening, flight delays continued.
Incident Details
The Potomac TRACON facility, located approximately 50 miles from Washington D.C., is responsible for managing regional airspace and providing air traffic control services to the Baltimore-Washington and Richmond-Charlottesville areas. A chemical odor was reported within the facility.
Transportation Secretary Sean Duffy stated that an overheated circuit board was identified as the cause of the odor. The circuit board was subsequently replaced, and air traffic controllers were cleared to return to the building.
Emergency medical services (EMS) evaluated some employees who experienced mild symptoms; however, no personnel required hospital transport, and no injuries were reported.
Operational Impact
The detection of the odor led to ground stops initiated around 5:30 p.m. on Friday. Airports affected included:
- Thurgood Marshall Baltimore-Washington International (BWI)
- Reagan National (DCA)
- Dulles International (IAD)
- Richmond International Airport
- Charlottesville-Albemarle Airport
The ground stops were lifted by 7:45 p.m. on Friday. Despite the lifting, ground delays and flight disruptions continued.
Data indicated that between 25% and one-third of all flights departing from the affected airports experienced delays. Flight delays of up to three hours or more were reported, extending through Friday night into Saturday morning. Aviation experts anticipated ripple effects on flight schedules throughout the night and potentially into the next day.
Passengers reported experiencing extended waits on tarmacs and instances of deboarding before reboarding flights hours later.
Emergency Response
In response to the reported potential hazardous materials incident, the Fauquier County Fire Rescue System and Prince William County’s hazardous materials team responded to the TRACON facility.
