A fiber-optic cable was damaged by a construction contractor on October 14, 2026, at George Bush Intercontinental Airport (IAH) in Houston, Texas, causing a major disruption in air traffic control communications.
The Federal Aviation Administration (FAA) issued a ground stop for inbound flights to IAH on the evening of October 14, 2026. The agency warned that the ground stop could be expanded to affect additional flights, stating in an operations advisory, “IAH has lost major communications and users can expect the current ground stop to be extended and expanded.” The cable damage led to significant flight delays throughout the evening.
Operational Response and International Processing Delays
Repair crews were dispatched immediately to address the fiber-optic line damage at IAH. Houston Airports coordinated closely with airlines and U.S. Customs and Border Protection to manage the impact, particularly concerning lengthened processing times for international arrivals passing through customs due to the communication outage.
Other Houston Airports Unaffected
According to the FAA, William P. Hobby Airport and other airports within the Houston terminal area remained unaffected by the fiber-optic cable damage. No operational disruptions or ground stops were reported at these locations on October 14, 2026.
Related Incidents and FAA Modernization Efforts
This disruption at IAH followed a similar incident on October 13, 2026, at Raleigh-Durham International Airport, where
a contractor severed a fiber-optic cable during construction work. That event caused multiple FAA ground stops, flight cancellations, and arrival delays exceeding two hours. Both incidents underscore the ongoing challenges the FAA faces with aging air traffic communications infrastructure, which the agency is actively working to modernize.
