During initial climb-out on a southwesterly direction, while at an estimated altitude of 90 feet above the ground, and an estimated airspeed of 25 knots, the helicopter experienced an un-commanded reduction of engine power to flight idle. The 358-hour student pilot turned the helicopter 180 degrees, put the collective down, and applied right anti-torque pedal. The helicopter landed hard on a street, impacting on all four landing gear before bouncing back into the air. During the second ground impact, the left rear landing gear collapsed and the main rotor blades and tail rotor made contact with the ground. The winds at the time of the mishap were reported from 040 degrees at 8 knots. The reason for the reported loss of engine power could not be determined.
Probable Cause: The partial loss of engine power for undetermined reasons. A contributing factor was the lack of suitable terrain for the forced landing.
