| Confidence Rating: |  Accident investigation report completed and information captured |
The pilot reported that he had accomplished about six landings without incident prior to the final landing. During the landing roll, when the tailwheel contacted the surface, a severe vibration was felt. The aircraft immediately weathervaned to the right into the wind. Left rudder control and braking action were not effective and the aircraft subsequently ground looped. Post-accident inspection noted a loss of friction to the tailwheel anti-shimmy clutch. Both steering springs were also disconnected.
Probable Cause: Directional control was not maintained during the landing roll. A steering spring disconnected as a result of a tailwheel shimmy was a factor.
