## Probable cause

The pilot's failure to maintain directional control of the airplane during landing.

## Findings

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

- [Performance/control parameters: directional control](https://openairdocs.org/ntsb-findings/01062020): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Stinson 108-1, 10 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md?model=9230404), [All aircraft, 3,958 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md)

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing-landing roll: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Stinson 108-1, 13 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=9230404), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

The pilot reported that he was landing at his destination in the conventional gear airplane. The airplane touched down normally and approximately 300 feet into the landing roll, the airplane veered to the left, which resulted in a right main gear collapse under the fuselage. The right wing tip was also bent. The pilot indicated that there were no mechanical anomalies
