NTSB narrative
The pilot landed the Piper PA-24-250, 200-300 feet beyond the displaced threshold of the 2,200 foot long dry, upsloping, grass runway. After touchdown he observed a deer standing slightly right of the runway centerline and chose not to attempt a go-around maneuver on the unidirectional runway because of the upsloping runway condition and tall trees at the north end. The pilot believed that the deer was too close to allow the aircraft to stop in time and thus maneuvered to the left side of the runway trying to avoid a collision. He applied full brakes and during the landing roll, the aircraft departed the left side of the runway encountering an embankment and ground looping to a stop. The pilot reported that the runway width was 50 feet with an approximate 25 feet of additional surface outboard of each side of the runway.
Probable cause
The pilot's failure to maintain adequate directional control. Contributing factors were the embankment and the deer.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
