Faults in the data transmission network that supports air traffic control services were detected before 6:00 on October 16, 2026, causing disruptions at multiple Italian airports. The national air navigation service provider Enav implemented flow management measures from 6:00 to temporarily reduce the capacity for handling aircraft in Italian airspace to maintain safety amid increasing traffic.
At least four flights were cancelled at Rome Fiumicino airport on routes to Milan Linate, Riyadh, Tirana, and Trieste. Other flights out of Rome Fiumicino experienced delays of up to 60 minutes. The disruptions extended to Milan Linate, Milan Malpensa, and Naples Capodichino airports,
where cancellations and delays were also reported.
Enav Statements on Operational Safety
Enav confirmed that normal air traffic management without capacity reduction was maintained until 6:00 on Friday. It emphasized that the flow management measures were necessary due to the persistent faults and a rise in air traffic, stating, “From 6:00, in view of the steady increase in air traffic and the persistence of the faults, in order to continue guaranteeing the highest level of operational safety, flow management measures have been introduced, which mean a temporary reduction in the capacity to handle aircraft in Italian airspace.” Enav also ruled out any connection between the
faults and hacking or sabotage.
Enav continues to investigate the causes of the data network disruptions and is working to restore full system functionality.
Passenger Impact and Advisory
Passengers traveling through Italian airports on October 16, 2026, faced delays and cancellations linked to the data network fault affecting air traffic control. Airport operators strongly urged travelers to verify the status of their flights directly with their airlines before arriving at the airports.
