Repeat chemical odor at Potomac TRACON forces brief ground stops at Reagan, Dulles and BWI

Airports serving Washington, D.C., Baltimore and some Virginia cities briefly halted flights after a strong chemical smell at the Potomac TRACON prompted evacuation and FAA ground stops at Reagan National, Dulles and BWI. The FAA later lifted the stop; a similar incident two weeks earlier involved an overheating circuit board.

Briefing

What Hype is tracking

  • The FAA imposed brief ground stops at Reagan National (DCA), Dulles (IAD) and BWI before lifting restrictions, directly disrupting arrivals and departures across the Washington–Baltimore airspace and creating immediate operational risk for carriers and airports.
  • This is the second ATC facility evacuation this month and follows a recent overheating circuit‑board replacement, highlighting equipment reliability and contingency-readiness issues for terminal radar approach facilities; see prior ATC evacuations [source:c4e4e5e1-c613-4376-81e2-2c32bdca6560] and recent Reagan National ATC upgrades [source:73e4b4e0-a3c0-4e1f-bae8-e4352feb413d].
