Collision with terrain involving a Robinson Helicopter Co R22 BETA, VH-AOW, 28km NW Limbunya, NT on 9 November 1993

The helicopter was being used for feral animal culling with the pilot and a shooter on board. Weather conditions at the time were hot, and the helicopter was operating close to its maximum all up weight. While flying downwind the helicopter began to sink and the pilot overpitched the main rotor system while attempting to recover. The resultant loss of rotor RPM caused the helicopter to descend rapidly and strike a tree. Both occupants escaped with minor injuries but the helicopter was destroyed.
