NTSB narrative
The pilot reported that, during takeoff, he felt a shimmy in the tailwheel-equipped airplane. During the subsequent three-point landing, the airplane veered left immediately upon touchdown. The airplane departed the left side of runway and ground looped, which collapsed the right main landing gear and substantially damaged the right wing. An NTSB structures engineer’s review of postaccident photographs of the tailwheel assembly determined that deformation and fracture features on the fitting flanges on the extruded base of the tailwheel assembly were from a twisting motion about the single bolt that secured the tailwheel assembly to the suspension assembly, consistent with that resulting from a tailwheel shimmy event. The accident circumstances and damage evidence are consistent with a failure of the tailwheel assembly due to improper movement or rotation around the tailwheel attachment bolt during the shimmy event during takeoff, which resulted in a subsequent loss of control of the airplane during landing. However, the investigation could not determine if the shimmy event resulted from a loose attachment bolt, or if the movement around the attachment bolt resulted from the shimmy event.
Probable cause
The pilot’s inability to control the airplane during landing due to tailwheel assembly damage sustained during a previous shimmy event that occurred for reasons that could not be determined based on the available evidence.

- 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, cause areas. 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.
