## Probable cause

The pilot’s excessive application of brakes while landing, which resulted in a nose gear collapse.

## 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: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Ryan NAVION A, 1 case](https://openairdocs.org/ntsb-events/094/sequence.md?model=6150162), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md)
- [Landing-landing roll: Runway excursion](https://openairdocs.org/ntsb-events/300); cases with it: [Ryan NAVION A, 1 case](https://openairdocs.org/ntsb-events/300/sequence.md?model=6150162), [All aircraft, 3,643 cases](https://openairdocs.org/ntsb-events/300/sequence.md)

## Analysis

During the landing roll, the nose gear collapsed, and the airplane departed the runway, substantially damaging the fuselage and engine mounts. The pilot reported that he applied the brakes upon touchdown for a short field landing and believed the nose gear collapsed due to “pushing down the nose.” A postaccident examination of the landing gear system revealed no anomalies that would have precluded normal operation.
