Final report, still had at least 60 litres of fuel, engine had stopped prior to crash.
Findings
As the helicopter climbed to about 650 ft above ground level, the engine lost power. The reason for the power loss was not determined. A detailed examination of the engine and airframe was not performed, limiting the ability to identify the reason for the power loss
The power loss was not immediately recognised which limited the opportunities for a safe forced landing. During the forced landing, the helicopter did not have sufficient height to reach the selected landing area and collided with rooftops
