Brief

Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.

What happened

On 22 March 2018, an Airbus A320-232 was on descent into Cairns, Queensland (Qld) when it encountered severe turbulence. A cabin crew member in the rear of the aircraft sustained a broken ankle as a result.

The aircraft was flying in and out of cloud at the time of the occurrence and the pilot reported that the weather radar only showed green patches, indicating nil significant turbulence. The seat belt signs were therefore not illuminated.

The pilot reported that no turbulence was forecasted or expected. No encounters with turbulence had been reported prior to the occurrence.

Safety message

The ATSB research report Staying safe against in-flight turbulence (AR-2008-034) details that while turbulence is normal and occurs frequently, it can be dangerous. It is rarely a threat to passenger aircraft or to pilot control of the aircraft. In a typical turbulence incident, 99% of people on board receive no injuries. The report discusses what you can do to stay safe.
