What Happened
On 7 December 2023, at 1930 local time, a Robinson R22 Beta 2 helicopter, registered VH-DLD, departed from Bloodwood Station, Northern Territory, on a private flight to Gorrie Station. The helicopter was last seen by witnesses on the ground at approximately 1945, and a search was initiated at about 2015. The wreckage was located on the afternoon of 9 December. The helicopter was destroyed and the pilot, the sole occupant, was fatally injured.
ATSB Findings
The Australian Transport Safety Bureau (ATSB) determined that the pilot departed after last light on a moonless night, but was not qualified to operate at night and the helicopter was not equipped for night flight—specifically, it lacked an artificial horizon. Although the pilot had some night flying experience, the absence of the minimum instruments and training made it unlikely that the pilot could orient the helicopter without external visual references.
Witnesses at Wyworrie Station observed the helicopter fly past at about 1945, noting very dark conditions and smoke from bushfires between Wyworrie and Gorrie. The pilot made a radio call to the Gorrie caretaker asking if hangar lights were on, which the caretaker interpreted as sounding disoriented. The last radio call, dark night conditions, and satellite imagery indicated the pilot likely flew into a smoke plume.
The wreckage was found approximately 7.5 km south of Wyworrie homestead and 6.1 km north-north-east of Gorrie homestead, on a track consistent with the direction to Gorrie. The forecast visibility reduction to 5 km in smoke likely placed the lights of both stations beyond visual range at the accident site. It is possible the pilot’s eyesight had not fully adapted to darkness, and the ATSB could not determine if the pilot was wearing prescription night driving glasses.
The ground scar, broken landing skids, and wreckage distribution indicated a nose-down, right roll attitude at impact, with high energy in both airspeed and rotor speed. The evidence suggests that after passing Wyworrie homestead, the pilot lost external visual references in smoke on a dark night, became spatially disoriented, and the helicopter collided with terrain uncontrolled at high speed.
Safety Message
The ATSB noted that night conditions can eliminate usable external visual cues, putting day VFR pilots at risk of spatial disorientation. They referenced their Avoidable Accidents No. 7 report and CASA Advisory Circular AC 61-05 v1.1 for guidance on night VFR operations. The ATSB encourages all involved in night flying to familiarize themselves with these resources.
