Probable cause

The overspeed of the main rotor system for reasons that could not be determined based on the available information.

NTSB narrative

The private pilot stated that, while approaching the landing site at the conclusion of the 50-minute flight, the helicopter's main rotor experienced an overspeed condition. The pilot reduced the throttle but was unable to reduce the rotor rpm, and he initiated an autorotation to a field. The pilot reported that the helicopter's rotor had oversped about 2 weeks before the accident. A 50-hour inspection after the previous overspeed event did not reveal any anomalies. A postaccident visual examination of the helicopter by inspectors from the Federal Aviation Administration did not reveal any anomalies, and the reason for the overspeed of the main rotor system could not be determined.
