The DC-area airports are once again facing disruptions, this time due to a strong odor reported at the Potomac Consolidated Terminal Radar Approach Control (TRACON) facility in Warrenton, Virginia. This incident, which occurred on March 27, 2026, caused significant delays and 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 issue was traced back to an overheated battery inside an IT cabinet at the TRACON facility.

Why it matters

This incident is particularly concerning as it comes on the heels of a similar issue just a month prior, highlighting the delicate balance and interconnectedness of the air travel industry. Any disruption at this key air traffic control facility can have a ripple effect across the entire system, affecting thousands of travelers. The ongoing partial government shutdown has further exacerbated the impact of these delays.

The details

The March 27 incident was caused by a strong odor reported at the Potomac Consolidated TRACON facility, which manages a large portion of the region's airspace. The odor was traced back to an overheated battery inside an IT cabinet. This led to the evacuation of the facility and ground stops at the nearby airports. A similar incident had occurred just a month prior on March 13, when a strong odor was reported due to faulty equipment being worked on by a contractor, also resulting in an evacuation and ground stops.
