2008 A Qantas A330-300 aircraft operating from Perth to Singapore on 27 December 2008 was involved in an incident approximately 260 nautical miles (480 km) north-west of Perth at 1729 WST, while flying at FL360. The autopilot disconnected and the crew received an alert indicating a problem with Air Data Inertial Reference Unit #1. The crew performed a reset procedure and returned to Perth uneventfully. The ATSB included the incident in their accident investigation of an earlier incident on Qantas Flight 72. The incident again fuelled media speculation regarding the significance of the Harold E. Holt naval communications facility, with the Australian and International Pilots Association calling for commercial aircraft to be barred from the area as a precaution until the events could be better understood, while the manager of the facility claimed that it was "highly, highly unlikely" that any interference had been caused.
