Britain’s Civil Aviation Authority (CAA) has announced an independent investigation into the air traffic control software failure at NATS on September 8, 2026, that grounded thousands of flights and left hundreds of thousands of passengers stranded across airports in the UK and Europe.
Scale of Disruption and Calls for Accountability
The software failure disrupted multiple European airlines, forcing widespread cancellations and delays. Ryanair has repeatedly demanded the resignation of NATS CEO Martin Rolfe in the wake of the incident, criticizing the company’s handling of the crisis.
Scope of the Civil Aviation Authority Review
The CAA’s review will examine NATS’s report on the root causes of the technical failure, evaluate the impact on consumers, and
identify any further measures necessary to prevent recurrence. The investigation will also scrutinize NATS’ strategies for upgrading, replacing, and modernizing its critical operational systems.
Additionally, the regulator will assess how effectively NATS implemented recommendations from previous reviews and will incorporate lessons from international air traffic control best practices.
Official Statements and Reporting Deadlines
UK Transport Secretary Heidi Alexander said, “In recent weeks, passengers and airlines have been let down too many times, and I’m determined to get to the bottom of why.” She emphasized the expectation of “answers and action” following the investigation.
A spokesperson for NATS expressed support for the CAA’s review scope and
pledged full cooperation with the regulator throughout the process.
The CAA is expected to deliver an initial report to the Transport Secretary by the end of January 2027, with a final report due by March 8, 2027.
