- 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
- Initial climb
- 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
- 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
- Fuel starvation; Tree(s)
- 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 PLT/OWNER OF THE NEW HOME BUILT ACFT MADE SVRL TAXI CHECKS BEFORE THE 1ST FLT. CHECKS WERE MADE WITH THE NOSEWHEEL OFF THE RWY & A LIFT-OFF TO ABOUT 10 FT AGL. DURING TAKEOFF, AT ABOUT 100 FT AGL, THE ENG LOST POWER. THE PLT ELECTED TO LAND ON THE OVERRUN AT THE DEP END OF THE RWY, BUT THE ENG BEGAN RUNNING AGAIN, SO HE ELECTED TO CONT THE TAKEOFF & RETURN TO THE RWY FOR LANDING. HOWEVER, THE ENG LOST POWER AGAIN & THE PLT WAS FORCED TO LAND IN TREES BEYOND THE DEP END OF THE RWY. A POST-ACDNT EXAM OF THE ACFT REVEALED THE FUEL VENT WAS BLOCKED BY A MUD DAUBER NEST.
Probable cause
FUEL STARVATION DUE THE FUEL VENT BEING BLOCKED BY A MUD DAUBER NEST AND THE PILOT'S FAILURE TO FIND THE OBSTRUCTION (INADEQUATE PREFLIGHT) BEFORE TAKING OFF. TREES BEYOND THE DEPARTURE END OF THE RUNWAY WERE A RELATED FACTOR.

- 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: 6568d5967a8d3ea15f509fe3d2aae99495c3cf72e835bb3eb41cfa60a8eb9b38; retrieved 2026-09-21T23:57:58.747Z.
