Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The pilot misjudging his altitude due to the white out conditions. Contributing to the accident was the pilots lack of experience in this aircraft and this type of operation.

Analysis

The pilot was making practice aerial applications in preparation for his CFR 137 certification. The main gear contacted the snow covered terrain during a low level maneuver. The aircraft then cartwheeled. The pilot reported only two hours of flight experience in this type of aircraft.
