Accident Narrative
The pilot attempted to activate the radio-controlled runway boundary lights from approximately 10 miles away and also while in the traffic pattern, but was unsuccessful. He continued his descent to about 500 feet above the ground using the visual approach slope indicator (VASI) lights. The pilot stated that he had the airport in sight and felt well enough in sight to complete the landing.
The airplane touched down in approximately 18 inches of snow, 60 feet off the right side of the runway. The pilot reported that there was no mechanical malfunction. He said that as he got closer to the ground he realized it was snowmobile tracks and not the runway. He tried to go-around but the airplane impacted the ground, collapsing the nose gear.
Probable Cause
The probable cause, as determined by the official investigation, was the pilot's inadequate inflight decision to continue a landing without runway lights, and his delay in initiating a go-around. A related factor was the pilot's overconfidence in his ability.
