## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Landing: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Stinson 108, 7 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=9230402), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

During landing the pilot lost control of the airplane and it veered off the left side of the runway. On departing the runway, the airplane nosed over and came to rest inverted, which resulted in substantial damage to the wing struts and spar, fuselage, and the vertical stabilizer and rudder. Inspectors from the Federal Aviation Administration examined the airplane at the scene and found no anomalies. On speaking with the pilot, the pilot told them that he had lost control.
