- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Low altitude operation/event
- 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
- 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 commercial pilot was flying his company's helicopter during a low-altitude cattle herding flight. A witness saw the helicopter maneuvering over power lines; it subsequently descended in a nose-low attitude to ground contact and was consumed by postcrash fire. Both the power lines above the helicopter wreckage and the helicopter itself exhibited damage consistent with in-flight contact with the lines. An onscene examination of the wreckage did not reveal any preimpact anomalies that would have precluded normal operation of the helicopter.
Probable cause
The pilot's failure to maintain clearance from powerlines while maneuvering at low altitude.

Source notes (4)
- 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.
