## Findings

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

- [Object/animal/substance: animal(s)/bird(s)](https://openairdocs.org/ntsb-findings/03022045): Environmental issues › Physical environment · Ability to respond/compensate (probable cause); cases with it: [Cirrus Design SR22, 5 cases](https://openairdocs.org/ntsb-findings/03022045/cases.md?model=2130001), [All aircraft, 358 cases](https://openairdocs.org/ntsb-findings/03022045/cases.md)

## Sequence of events

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

- [Takeoff: Birdstrike](https://openairdocs.org/ntsb-events/901) (defining event); cases with it: [Cirrus Design SR22, 3 cases](https://openairdocs.org/ntsb-events/901/sequence.md?model=2130001), [All aircraft, 253 cases](https://openairdocs.org/ntsb-events/901/sequence.md)

## Analysis

The pilot reported that, during the takeoff roll, multiple geese flew across the runway. One goose struck the propeller, and another struck the windshield. Subsequently, the airplane yawed to the right into tall grass, and the airplane then spun 180° and came to rest with the landing gear sheared off. The airplane sustained substantial damage to the fuselage and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
