Probable cause
The pilot's failure to maintain directional control of the airplane. Contributing to the accident were the snow berm and the pilot's lack of total experience in the type of operation (ski equipped airplanes).
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
Just after touchdown on the plowed half of the runway the right ski contacted the edge of the snow berm, causing the airplane to ground loop. The pilot stated that in retrospect she should have landed on the unplowed half of the runway.
