Aircraft Accident/Incident Report

Staples, Texas 78670
Monday, March 5, 2012 11:36 CST

NTSB Narrative Summary Released at Completion of Accident

About 15 minutes into a cross-country flight, the pilot heard a "pop" that sounded "like metal breaking." He felt a violent vibration and loss of torque pedal response. The pilot reported that there was no change in rpm, and he performed a precautionary autorotation and landing due to the vibration. During the landing, the helicopter impacted the ground hard and the main rotor blades contacted the tailboom. On-scene and subsequent laboratory examination revealed no anomalies that would have precluded normal operation. The reason for the pop and subsequent vibration could not be determined.

NTSB Probable Cause Narrative

The pilot's failure to attain the proper descent rate during autorotation, which resulted in a hard landing. Contributing to the accident were the inflight vibrations and loss of torque pedal response for undetermined reasons.
