The ATSB is investigating a turbulence event involving Boeing 737, VH-VYK, being operated on flight QF520 from Sydney to Brisbane on 4 May 2024.
It was reported that as the aircraft was passing 9,000 ft on descent with the seatbelt sign on and cabin crew not yet seated, the aircraft encountered turbulence. One of the cabin crew members sustained a serious ankle injury. The flight crew notified ATC and an ambulance crew was waiting for the aircraft on arrival.
The evidence collection phase of the investigation will involve interviewing witnesses and involved parties, examination of maintenance records, retrieving and reviewing recorded data, and the collection of other relevant information.
Should a critical safety issue be identified during the investigation, the ATSB will immediately notify relevant parties, so that appropriate safety action can be taken.
A final report will be published at the conclusion of the investigation.
