What happened
On 11 February 2021, a Robinson R44 (registration VH-HKC) crashed into terrain in a remote area of Queensland during the period of astronomical twilight. The flight began from Reedy Springs, where the pilot departed in a hurry during a break in the weather without a formal alternate plan.
During the flight, the helicopter struck a powerline located on the Kennedy Development Road. Following this impact, the pilot continued to fly at a low altitude, likely using the road centerline illuminated by landing lights to navigate. After leaving the road, the pilot lost visual references due to the lack of ground lighting and the dark, overcast conditions. The aircraft subsequently descended into terrain at a speed of approximately 37 kt with a 13-degree nose-down flight path angle. The impact occurred with substantial energy, consistent with the engine delivering power to the rotors at the time of collision.
The investigation
The investigation focused on the pilot's decision-making and the aircraft's suitability for the flight conditions. Investigators found that the pilot did not hold a night VFR or instrument rating, and VH-HKC was not certified or equipped for night VFR or IFR operations.
At the time of the accident, the environment was extremely dark, with no lunar illumination and minimal terrestrial lighting. The investigation noted that the pilot had multiple opportunities to land safely or seek assistance via satellite phone or a personal locator beacon but chose to continue the flight. Furthermore, the pilot had been advised at previous stops to discontinue the flight, yet proceeded toward the destination despite the increasing darkness.
Findings
- The pilot attempted to maintain visual flight at low altitude during dark night conditions without adequate ground lighting.
- The pilot operated the aircraft at night without the necessary qualifications, experience, or appropriate equipment.
- The pilot continued the flight after the end of civil twilight despite having opportunities to land or seek assistance.
- The collision with a powerline served as a missed warning regarding the risks of flying in reduced visibility.
