What happened
The pilot reported that the accident occurred following the recent modification of his aircraft, specifically the installation of a tail wheel assembly. After touching down on runway 12, the pilot attempted to maintain control during the rollout phase. However, he lost directional control of the aircraft shortly after landing. The loss of control resulted in the airplane ground looping.
At the time of the incident, the wind conditions were calm, with a wind direction from 120 degrees at a speed of 5 knots. The pilot noted that he had accumulated 600 hours of flight time specifically in taildragger aircraft prior to this event.
The investigation
A post-accident examination of the airplane was conducted to determine the mechanical status of the aircraft. Inspectors found no evidence of any pre-existing mechanical malfunctions or failures that could have contributed to the loss of control.
