The Australian Transport Safety Bureau (ATSB) is investigating the collision with terrain involving Robinson Helicopter Company R44, registration VH-OCL, 8 km 340 degrees from  Kumarina Roadhouse Airport, Western Australia on 3 November 2022.

During initial climb, the helicopter’s rotor RPM began to decay and the low RPM warning horn and light activated. The pilot attempted recovery but was unable to restore rotor RPM. The helicopter subsequently collided with terrain resulting in substantial damage. Two passengers sustained serious injuries and one passenger sustained minor injuries.

The evidence collection phase of the investigation will include interviewing the pilot and witnesses, and the collection of other relevant evidence, including any recorded data, weather information, aircraft and pilot records.

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.
