On 16 August 2020, a Robinson R22 Beta, registration VH-YMU, was being utilised for cattle mustering operations in remote country, from the Rocky Point Yards, Northern Territory, south of the McArthur River Mine Aerodrome. At about 1200 Central Standard Time, the pilot was required to conduct an emergency forced landing. The helicopter landed heavily, resulting in substantial damage to the machine and serious injuries to the pilot. It was reported that the forced landing was as a result of failed engine to main rotor gearbox drive belts. Another helicopter operating nearby was landed at the accident site and the pilot of that helicopter transported the injured pilot of VH-YMU to the McArthur River Mine Site for evacuation and medical treatment.
