Investigating agency: NTSB
Confidence Rating: Accident investigation report completed and information captured
Narrative:
The commercial pilot reported that, during the agricultural application flight, the engine started to shake violently. The pilot executed a left turn and positioned the helicopter into the wind, but the helicopter started to descend, and the engine then lost power. The pilot conducted an autorotation, and the helicopter subsequently impacted the ground, which resulted in substantial damage to the tailboom. Postaccident examination of the engine revealed no evidence of preimpact mechanical malfunctions or failures that would have prevented normal operation.
Probable Cause: A loss of engine power for reasons that could not be determined because postaccident examination of the engine did not reveal any anomalies that would have precluded normal operation.
