Chemical odor triggers one-hour ground stop across four major DC-area airports
Four key airports serving the Greater Washington, Baltimore, and Richmond regions halted all flights for over an hour on Friday evening due to a strong chemical smell emanating from overheated circuit boards at nearby air traffic control facilities. The Federal Aviation Administration issued temporary ground stops affecting Ronald Reagan National Airport (DCA) as controllers struggled with visibility caused by fumes leaking into the Potomac facility, prompting significant delays and cancellations for travelers in Virginia's capital region.
Key Points
-
1A ground stop issued by the FAA halted flights across four major airports in and around Washington, DC due to a strong chemical odor emanating from an air traffic control facility.
-
2The issue was traced back specifically to Ronald Reagan National Airport (DCA) where overheated circuit boards were identified as the source of both smell and equipment malfunction.
-
3Flights remained grounded for approximately one hour on Friday evening before resuming operations after authorities confirmed no danger existed at controllers' workstations.
Developments
A strong chemical smell detected by officials led to an air traffic control shutdown affecting all three major airports serving the D.C. area due to overheating equipment inside Potomac TRACON's facility; however, firefighters confirmed no danger after replacing a faulty circuit board and operations resumed shortly thereafter.
Four major Washington-area airports halted landings on Friday evening due to a strong chemical smell emanating from Potomac TRACON that impaired air traffic controllers. This ground stop caused flight delays across the region, with roughly 25% of departing flights delayed and some reaching two hours long before operations resumed after 7 p.m., though landing restrictions remained in place at the time of reporting.
Four major Washington, D.C., area airports halted operations for over an hour due to a strong chemical odor emanating from Potomac TRACON that impaired air traffic controllers' ability to manage flights. This declaration caused flight delays across these hubs and the region's busiest airspace between 25% and one-third of departing aircraft were affected, with ground stops remaining in place after evening departures began at seven p.m. ET on Friday.
Flights across Ronald Reagan National Airport (Dulles), Baltimore/Washington Thurgood Marshall International Airport were temporarily halted due to a chemical odor caused by an overheated circuit board at the Potomac TRACON facility. The two-hour ground stop disrupted hundreds of flights during spring break travel, with delays ranging from one hour to over three hours across multiple airports in Washington and Virginia regions
