Incident Summary
A helicopter sustained substantial damage when it impacted vehicles and terrain during takeoff following a reported loss of engine power while in flight. The pilot and two passengers suffered minor injuries in the occurrence.
Pilot's Account
The pilot reported that all instrument indications were normal before departure. After a normal rate-of-climb takeoff, the aircraft experienced a momentary partial power loss. The pilot noted that altitude was insufficient to reduce collective to minimize power applications, and the helicopter began descending rapidly toward a parking lot filled with vehicles below. The pilot stated there was no other suitable terrain available for landing.
Witness Statement
A witness observed the helicopter nose over and move forward while gaining altitude. The witness then turned to speak with someone nearby but was drawn back by a change in the sound emanating from the helicopter.
Engine Examination
Following the accident, the engine was subjected to a test run. The test produced full rated power, indicating the engine was capable of normal operation after the event.
