- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary

- First occurrenceThe 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
- Loss of control in flight
- 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

NTSB narrative
The pilot said that smoke coming from the forest fire indicated winds were from the east. He approached the fire from the north, circled in a counterclockwise direction, and began his approach to the landing zone from the west. On approach, the helicopter lost tail rotor effectiveness and spun to the right. A firefighter on the scene recorded the wind from the southwest at 15 knots, but this information was not relayed to the pilot. The helicopter was not equipped with a high altitude tail rotor kit.
Probable cause
the pilot's inadequate in-flight planning and decision making, and the loss of tail rotor effectiveness. A contributing factor was the right quartering tailwind.

- 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, coordinates. 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.
- API snapshot SHA-256: e25f413aed41e84e9f7ab31a15ced027c9bf780d7dc1eb5dd880b7247d3f0951; retrieved 2026-09-18T21:18:29.492Z.
