Investigating agency: ATSB
The pilot of an amateur-built Wittman Tailwind aircraft, registered VH-TWQ, departed Evans Head Airport, Australia, with one passenger on board. The pilot was conducting a private flight under the visual flight rules from Evans Head, New South Wales to Boonah, Queensland.
The pilot flew in a north-north-westerly direction towards Boonah via the Richmond River valley. At 13:53, the pilot commenced a 180 turn overhead the township of Kyogle and diverted south back down the valley to Casino aerodrome, landing at 14:06.
At 14:54, the pilot took off from Casino and flew in a west-north-westerly direction. At 15:11, TWQ commenced a left turn and, shortly afterwards, collided with terrain. The pilot and passenger were fatally injured and the aircraft was destroyed.

Contributing factors
The pilot departed an interim landing site for Boonah under the visual flight rules with a high risk of encountering forecast cloud that reduced conditions below that required for visual flight.
It is likely the pilot encountered conditions of reduced visual cues and became spatially disorientated which led to a loss of control and collision with terrain.
