Probable cause
The failure of the pilot to maintain rotor rpm during a downwind turn. A factor in the accident was the inadequate altitude to recover from the loss of rotor rpm.

Read the full NTSB narrative
The helicopter pilot turned downwind at 30 feet above the ground. The winds were between 15 knots and 30 knots. The main rotor rpm decayed, and the pilot was unable to regain rpm by lowering the collective, disengaging the engine speed governor, and increasing the throttle. During the ensuing forced landing, the helicopter bounced and rolled onto its side. The pilot stated that he did not have tail rotor authority at the low rotor rpm when the helicopter bounced. The engine was operated on a test stand, and exceeded the minimum power requirements for a serviceable engine. No anomalies were noted with the engine, governor, or governor controller.
