NTSB Narrative Summary Released at Completion of Accident

The pilot, an employee of the National Park Service, related he was returning to his position as a Park Ranger/Pilot after a three month furlough from the park service. The purpose of the accident flight was to regain proficiency in the Piper PA-18 airplane. The pilot said that during the landing roll on the fourth landing, he lost directional control of the airplane, and it ground looped to the left, which resulted in substantial damage to the airframe. Also, the pilot said he did not fly during his furlough, and that his total flight experience in the PA-18 airplane was approximately five hours.

NTSB Probable Cause Narrative

failure of the pilot to maintain directional control of the airplane, which resulted in an inadvertent ground loop and damage to the airplane. Factors associated with the accident were: the ice/snow covered runway, and the pilot's lack of experience in the make and model of airplane.
