## Probable cause

The pilot's use of excessive braking during landing, which resulted in a nose-over.

## Findings

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

## Sequence of events

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

- [Landing-landing roll: Nose over/nose down](https://openairdocs.org/ntsb-events/096) (defining event); cases with it: [Stinson SR-9C, 1 case](https://openairdocs.org/ntsb-events/096/sequence.md?model=8631508), [All aircraft, 2,287 cases](https://openairdocs.org/ntsb-events/096/sequence.md)

## Analysis

The pilot reported that, during the landing roll, he applied brakes, and the airplane nosed over. The airplane sustained substantial damage to the left wing and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot added that he should have used "less…brakes."

## Factual narrative
