Probable cause

The pilot's inadequate preflight weather evaluation and the unsuitable terrain encountered during the precautionary landing at night. Contributing to the accident was the pilot becoming lost after inadvertently encountering fog while en route, the night lighting conditions, and the fence that the gyrocopter impacted during the landing rollout.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that the ground visibility was about 4 miles at the time of his departure. The intended destination was the pilot's farm, located about 17 miles northwest of the departure airport. While en route, about 2 miles from the intended destination, the airplane encountered fog and the pilot decided to return to the departure airport. The pilot stated that he "lost direction" and performed a precautionary landing in a field. During the landing rollout the gyrocopter impacted a fence and nosed over. The vertical fin, rudder, horizontal stabilizer, rotor head, rotor blades, and propeller were damaged. The weather conditions at the departure airport were visibility 4 miles with mist, broken ceiling at 200 feet above ground level (agl), overcast ceiling at 2,800 feet agl, temperature 4 degrees Celsius, and dew point 3 degrees Celsius. The accident occurred at night, about 12 minutes after civil twilight had ended. The pilot noted that the accident could have been prevented if he had called a neighbor prior to departure to determine what the actual weather conditions were near his intended destination.
