NTSB Narrative Summary Released at Completion of Accident

During the landing roll, the pilot braked to a stop with the nose wheel atop a snow drift. The pilot released the brakes and the airplane rolled backward. When the pilot reapplied the brakes the aircraft rocked rearward, pivoting on the main landing gear, and the tail struck the ground, damaging two fuselage bulkheads.

NTSB Probable Cause Narrative

The pilot's selection of unsuitable terrain for landing. Factors associated with the accident are snow drifts across the runway, and excessive braking during the rearward roll.
