Cyber-Related Outage of Collins Aerospace MUSE Disrupts European Airports as Brussels Orders Mass Cancellations

Officials say the failure is limited to passenger processing systems with manual workarounds in place and no impact on air traffic control.

Overview

  • The disruption began Friday night and continued into Sunday as airports relied on manual check-in and baggage procedures while Collins Aerospace worked to restore its MUSE software.
  • Brussels Airport reported the heaviest impact, asking airlines to cancel about half of Sunday departures and nearly 140 outbound flights on Monday to manage queues.
  • London Heathrow and Berlin saw delays and some cancellations, with Heathrow advising travelers to check with airlines, while Frankfurt and Zurich reported no impact.
  • Collins Aerospace and parent RTX confirmed a “cyber-related disruption” affecting select airports, emphasizing the issue was confined to electronic check-in and bag drop functions.
  • European and national cybersecurity bodies, including the European Commission, the UK’s NCSC and Germany’s BSI, are monitoring the incident, which has no identified perpetrator and has not affected aviation safety.
