NTSB narrative
The pilot reported that during a routine test flight, he felt an abnormal vibration and decided to divert to a nearby airport. After noting the wind conditions, the pilot entered the airport traffic pattern and proceeded to execute a wheel landing in the tailwheel-equipped airplane. As the tailwheel settled onto the runway, the airplane immediately veered to the right. Despite the pilot's control and brake inputs, the airplane continued to veer to the right and exited the runway. Subsequently, the airplane came to rest in a nose-low attitude adjacent to the runway surface. Examination of the airplane by a Federal Aviation Administration inspector revealed that the left and right top and bottom wing assemblies and fuselage were structurally damaged. Flight control continuity was established throughout the airplane to all flight controls. Movement of the tailwheel by hand revealed that it locked into its normal turning radius and subsequently broke free with little pressure. No anomalies could be found with the airframe; however, examination of the runway revealed a black rubber transfer mark with a width corresponding to the width of the airplane's tailwheel. The mark was not linear, but had a zigzag shape consistent with the tailwheel shimmying.
Probable cause
Loss of control during the landing roll for undetermined 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. 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.
