NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

After about 2 hours of flight, the aircraft was in cruise at 100 feet agl when the engine lost all power. The pilot landed in a field and drained water from the fuel. When he got the engine restarted, he attempted to take off, and during his takeoff roll the main landing gear entered a snow-covered area and the aircraft swerved into rocks. The pilot said that between flights he stored the aircraft with partially filled tanks in an area with high temperature variations over a 24-hour period. This practice enhances distillation of water in the tanks due to condensation.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's use of unsuitable terrain for takeoff. Factors were snow and rock covered terrain, inadequate aircraft preflight, improper aircraft servicing, and the fuel contaminated by water.
