- Total loss of engine power (non-mechanical)
- Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
- Wire, transmission
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The 10,100-hour pilot reported that during the flight, he heard a loud bang followed by a subsequent decrease in engine and rotor rpm. The pilot increased the throttle and regained engine and rotor rpm. The pilot added that during a precautionary landing, the engine lost power and the helicopter landed hard in an open field. A witness adjacent to the accident site reported seeing the helicopter strike a power line just prior to landing. Examination of the airframe and engine revealed no anomalies. The reason for the loss of engine power was undetermined.
Probable cause
The loss of engine power for undetermined reasons.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2004-08-01.
