D.C.-area ATC Evacuations Followed 2025 Smoke Event Which Injured Controllers

Key Takeaways

• April 2025 smoke caused medical certificate loss for controllers
• March 13 voice switch fire halted traffic >2 hours
• March 27 battery backup fire triggered 90‑minute ground stop
• FAA plans replace 462 voice switches, 34 installed already
• ATC facilities average 36‑64 years old, modernization urgent

Summary

The Potomac Terminal Radar Approach Control (TRACON) experienced three smoke‑related incidents within a year, beginning with an unreported April 2025 event that caused nausea, dizziness and permanent loss of FAA medical certificates for several controllers. In March 2024 the facility was evacuated twice—once on the 13th after a voice‑switch panel burned, halting traffic for over two hours, and again on the 27th when an overheated battery backup sparked a 90‑minute shutdown. Both evacuations forced ground stops at DCA, IAD, BWI and RIC, creating cascading delays across the East Coast corridor. The incidents highlight aging ATC equipment and the FAA’s urgent push for modernization.

Pulse Analysis

The Potomac Terminal Radar Approach Control (TRACON) has been the epicenter of three smoke‑related incidents in the past year. An unreported April 2025 event filled the control room with fumes, leaving dozens of controllers with nausea, dizziness and, in several cases, permanent loss of their FAA medical certificates. The same facility was evacuated on March 13, 2024 after a voice‑switch panel burned, grounding traffic for more than two hours, and again on March 27 when an overheated battery backup in the break room triggered a 90‑minute shutdown. Each evacuation forced ground stops at Washington’s DCA and IAD, Baltimore‑Washington BWI, and Richmond RIC, rippling delays across the congested East Coast corridor.

These disruptions expose a systemic problem: the nation’s air‑traffic‑control infrastructure is aging at an alarming rate. A 2023 FAA report shows en‑route facilities average 56‑64 years, while terminal facilities like Potomac TRACON average 36 years, far beyond their design life. In response, the FAA’s recent modernization blueprint earmarks $12.5 billion, with $2 billion dedicated to facility consolidation and equipment upgrades. The agency has already installed 34 of the 462 digital voice switches slated for replacement by 2028, a critical step toward eliminating the obsolete hardware that sparked the March 13 fire.

Beyond technology, the incidents raise labor and safety concerns. Controllers must retain a valid medical certificate; smoke‑induced illnesses can force permanent certification loss, shrinking the already tight staffing pool. Unions fear that consolidation and automation could jeopardize jobs, while Congress scrutinizes the $12.5 billion spend amid competing budget priorities. Nevertheless, reliable ATC operations are essential for the nation’s economic engine, and prolonged ground stops translate into millions of dollars in airline revenue loss and passenger inconvenience. A swift, transparent upgrade path will be pivotal to restoring confidence in the National Airspace System.
