The ATSB is investigating an engine failure or malfunction involving a Boeing 737, VH-VYH, at Sydney Airport, New South Wales, on 8 November 2024. The aircraft was operating as Qantas flight QF520, scheduled from Sydney to Brisbane, Queensland.
During take-off from runway 34R at Sydney Airport at about 1240, the aircraft's right engine sustained a failure or malfunction. The flight crew declared an emergency to air traffic control and returned to Sydney, landing on runway 34L. After being visually inspected and cleared by the Aviation Rescue Fire Fighting Service (ARFFS), the aircraft was taxied back to the gate and the passengers and crew disembarked normally. It was reported that some engine debris had exited the engine through the tailpipe and started a grass fire which was extinguished by the ARFFS. No other aircraft damage was evident.
As part of the evidence collection phase of the investigation, ATSB investigators have obtained and examined maintenance records, recorded data such as flight data and radio recordings, and have interviewed the flight crew. The engine and components are being examined at an appropriate facility.
The ATSB is awaiting information from an external party and is unable to further progress the investigation until that third party input has been received. As a result, the investigation has been deferred.
A final report will be released at the conclusion of the investigation. Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
