- 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
- 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
- Miscellaneous/other
- 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 reported that he filled his fuel tanks to full, for the first time since purchasing the airplane, to conduct a flight test to calculate fuel burn rate. A weight and balance calculation provided by the pilot showed that the airplane was over the maximum gross weight by about 25 lbs. During takeoff initial climb, he observed that the airplane was not climbing as he expected and realized he would not be able to clear the trees or powerlines ahead of his position. The pilot initiated a forced landing to a grass covered field, however, during the approach, he observed that the landing distance available was too short and landed with a side slip to arrest the airplane’s forward movement. Subsequently, the airplane landed hard, which resulted in substantial damage to wings and fuselage. The pilot that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's improper decision to take off with the airplane over its maximum allowable gross weight, which degraded its climb performance and led to a subsequent off airport landing.

- 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, cause areas. 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.
