The Australian Transport Safety Bureau (ATSB) has commenced a transport safety investigation into the collision with terrain of a Robinson R22 helicopter during aerial mustering operations at Limbunya Station, about 500 km south of Darwin.

The ATSB is deploying investigators from its Canberra office, with experience in helicopter maintenance and engineering, to the accident site to begin the evidence collection phase of the investigation.

Over coming days investigators will examine the helicopter wreckage, survey and map the accident site with a drone, and collect any relevant components for further examination and analysis at the ATSB’s technical facilities in Canberra.

Investigators will also obtain and review any recorded data, weather information, witness reports, and aircraft operator procedures and maintenance records.

The ATSB anticipates publishing a preliminary report, which will detail factual information established during the investigation’s initial evidence collection phase, in approximately 6-8 weeks.

The ATSB will publish a final report, detailing contributing factors and any identified safety issues, at the conclusion of the investigation.

However, should any critical safety issues be identified at any stage during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate safety action can be taken.
