The pilot was descending the helicopter from about 1,000 feet above ground level (agl) and setting up for a landing at an off-airport location. At 300 to 500 feet agl, the pilot felt a major vibration in the helicopter. He immediately initiated an autorotation and landed the helicopter. During the forced landing, the helicopter rolled over on its right side and sustained substantial damage. Examination of the engine revealed that the No. 3 connecting rod had failed. Material examination of the connecting rod showed the rod failed due to multiple fatigue cracks.
Probable Cause: The failure of the engine connecting rod due to fatigue.
