Collision with terrain involving a Bell Helicopter Co 47G-3B1, VH-KHY, Bindoon, WA on 28 February 1993

The aircraft was conducting joy-flights near a Rock Festival. The pilot aborted a take-off attempt when it became clear to him that he would not obtain translational lift in time to clear trees at the end of the selected take-off area. He chose to air-taxi to a more suitable pad. To get to the pad, he had to air-taxi between two large trees. Whilst passing between the trees the pilot concentrated on rotor clearance and did not notice a wind gust which moved the aircraft towards the tree on the left. The main rotor hit a branch, forcing the pilot to take immediate recovery action. The aircraft landed heavily.
