- Aircraft age
- Not recorded
- 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
- Part 91: General Aviation
- Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
- Approach · VFR pattern final
- 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 engine power
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
- Substantial
Cause areas
- Pilot in command › Directional control, not maintained
- Pilot in command › Flare, improper
- Pilot in command › Recovery from bounced landing, not possible
- Reason for occurrence undetermined
- Weather condition › High density altitude
Approximate · Coordinates as recorded by the NTSB; no uncertainty radius is established.
NTSB narrative
PLT STATED AFTER ACCIDENT THAT HE HAD A MINOR ENG PROBLEM PRIOR TO DEPARTURE FROM BIG TIMBER. HE STATED THAT THE PROBLEM WAS CORRECTED AND THE FLIGHT COMMENCED TO BILLINGS. WHILE ON FINAL APPROACH TO RWY 04 AT BILLINGS THE PLT EXPERIENCED A PARTIAL LOSS OF PWR. HE WAS ABLE TO LAND ON THE RWY BUT BOUNCED THE ACFT SEVERAL TIMES ON TOUCHDOWN. THE PLT WAS UNABLE TO RECOVER AND THE ACFT DEPARTED THE SIDE OF THE RWY. THE DENSITY ALT WAS CALCULATED TO BE 6,344 FT. NO REASON FOR THE PARTIAL LOSS OF PWR COULD BE DETERMINED.

Source notes (5)
- 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.
- API snapshot SHA-256: f5b6ca678e3e7c3ad4bb1b2ae0953ad3754484e01757074732c5d2b36eec5620; retrieved 2026-09-23T14:10:03.306Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: destination. The narrative states "THE FLIGHT COMMENCED TO BILLINGS" and the partial power loss came "WHILE ON FINAL APPROACH TO RWY 04 AT BILLINGS"; the destination was not recorded.
