NTSB narrative
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.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
