After a stopover at his private property after about a 30-minute break, the pilot conducted take-off with a fully occupied helicopter. Having taken off, while hovering at the altitude of approx. 2–3 m AGL, the helicopter started left-spinning. The pilot lost control of the helicopter, which, several spins later, crashed into a tree standing in the close proximity of the take-off place. Once the rotating surfaces touched an obstacle, the helicopter tilted sharply and having fallen on the ground, remained lying on the left side. The helicopter was damaged heavily due to its collision with an obstacle and crash on the ground. The pilot and passengers left the helicopter cabin unaided, and were not injured.

The cause of the air accident was an inappropriately chosen method of take-off and subsequently mismanaged piloting of the helicopter in hovering. A gust of wind and a little experience of the pilot with the take-off of a helicopter at the limit of the maximum take-off weight could have been joint influences in the cause of the accident.
