- Collision with terrain/object (non-CFIT)
- 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 was flying with a pilot rated passenger who was becoming familiar with the flight characteristics of the airplane. As they turned final for the runway, the airplane began a rapid descent. The. pilot took control of the airplane and added full power for a go-around; however, he was unable to recover. The airplane subsequently struck an airport light pole, lost directional control, and came to rest inverted in a gravel parking lot, resulting in substantial damage to the wings and fuselage. The pilot stated he did not monitor the developing situation fast enough to recover. He reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation.
Probable cause
Pilot’s inadequate supervision of the pilot rated passenger’s actions, which led to a high descent rate and collision with obstacles.

Source notes (4)
- 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, coordinates, 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.
