FAA Halts Traffic at Washington Area Airports Over Odor at Facility

WASHINGTON, March 27 (Reuters) – ⁠The ⁠Federal Aviation Administration ⁠halted traffic at the three primary Washington, ​DC-area airports late on Friday after an odor was detected ‌at a Virginia air ‌traffic control facility, the agency said.

The FAA ⁠said ⁠the odor forced the evacuation of Potomac Consolidated Terminal ​RADAR Approach Control or TRACON, which controls airspace over numerous airports in the Washington region. The FAA issued ground ​stops at Reagan Washington National Airport, Washington Dulles, ⁠Baltimore and ⁠smaller airports in Charlottesville ⁠and ​Richmond around 6:40 p.m. EDT.

It is the second time ​in two weeks ⁠an odor at the facility in Warrenton, Virginia has snarled traffic.

A person briefed on the matter said the odor was a burning smell that appeared ⁠similar to an issue that prompted the FAA on March ⁠13 to halt air traffic. The FAA said on March 13 it had halted work because of a strong chemical smell tied to a circuit board that overheated.

Flightradar24, a flight tracking site, said inbound flights are holding or diverting. The airports have not had a departure since ⁠6:40 p.m. EDT. The FAA said an update was expected around 8 p.m. EDT.

FlightAware said 25% of flights at Baltimore and National were ​delayed and 11% at Dulles.
