On 30 November 2022, at 1315 Pacific Standard Time (2115 Coordinated Universal Time), an Arion Lightning aircraft, registered N60MY, departed controlled flight on approach to Zamperini Field (California, United States), and collided with terrain short of the runway. The two occupants were fatally injured.
The United States National Transportation Safety Board (NTSB) investigated this occurrence. As Australia was the State of Manufacture of the aircraft's engine (Jabiru 3300), the NTSB requested appointment of an Accredited Representative from the ATSB. To facilitate this request, the ATSB as the Accredited Representative initiated an external investigation under the provisions of the Transport Safety Investigation Act 2003.
On 5 December 2024, the NTSB released the final investigation report into this accident. Accordingly, the ATSB has concluded its involvement in the investigation. A copy of the report can be requested from the NTSB at https://www.ntsb.gov. Any enquiries relating to the investigation should be directed to the NTSB.
