- 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
- In flight collision with object
- 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, transmission
- 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 pilot made two approaches to the east end of the grass airstrip. On the first approach he performed a touch-and-go, and on the second he did not touch down, but instead flew low over the length of the runway. At the end of the second approach, the pilot pulled up steeply, climbed a few hundred feet, and then entered a steeply banked right turn, resulting in a course reversal. After the reversal, he entered a rapidly descending slip toward the west end of the runway. Just after terminating the slip, the aircraft impacted 40 foot high power lines that were located about 20 feet from the runway threshold.
Probable cause
The pilot's failure to maintain clearance from a transmission wire while on final approach. A factor was a 40-foot high transmission wire located approximately 20 feet from the end of the airstrip.

- 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.
