- Initial climb
- 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
- Fuel starvation
- 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 engine lost power after takeoff and the pilot landed in a nearby field, where both wings collided with fence posts. The pilot reported that the left fuel tank was about 1/4 full and the right fuel tank was empty. He had the left fuel tank selected during start up and taxi. As he did his pre-takeoff engine run-up checks, he switched fuel tanks per his normal procedure but did not return the selector valve to the left tank prior to departure. Both wings sustained substantial damage during the accident sequence.
Probable cause
A loss of engine power during takeoff due to fuel starvation as a result of the pilot’s selection of an empty fuel tank prior to departure.

- 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.
