NTSB narrative
The pilot stated that the tailwheel-equipped airplane started veering to the right during the landing roll. Despite his control inputs, the airplane continued to veer to the right, exited the runway, and tipped onto its left wing tip, damaging the left elevator, before coming to rest upright within a snow bank. According to the pilot, the left tailwheel steering link (spring retaining clip), Univair Part number 2133, was missing from the tailwheel assembly and a search failed to locate it on the runway or near the airplane. A missing tailwheel steering link would allow the tailwheel to freely caster.
Probable cause
The loss of directional control during the landing roll due to the separation of the tailwheel spring retaining clip for unknown reasons.

- 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, coordinates. 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.
