| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that, about 3 minutes after takeoff, the helicopter yawed left. The pilot stated that he lowered the collective and initiated a descent for an autorotative landing and that the cabin then filled with smoke. He landed the helicopter uneventfully in a field and exited it. Subsequently, he noticed a fire in the engine compartment. Inspection of the engine revealed damage to the Nos. 5 and 8 bearings consistent with the reduced oil supply to the bearings during engine operation, which resulted in a catastrophic engine failure. Due to the severity of the damage to the bearing components, it could not be determined whether any preaccident malfunctions or failures existed in the bearing assembly that could have led to the reduction in the oil supply.
Probable Cause: A total loss of engine power due to oil starvation at the Nos. 5 and 8 engine bearings, which resulted in a catastrophic engine failure.
