What happened

The pilot was flying to the destination airport at night on the second day of a long cross-country trip. Radar data showed that when the airplane was about 12 miles from the destination airport, it began to descend. The airplane eventually descended into trees and terrain about 6 miles from the destination airport, at an elevation nearly 400 feet below the airport's traffic pattern altitude, and 1,400 feet below the maximum elevation figure published for that area.

A state police helicopter dispatched to search for the airplane following the accident reported that the terrain surrounding the accident site was "surprisingly" dark, and that some of the only nearby ground lighting came from a parking lot about 1 mile beyond the accident location and along the airplane’s course . According to the aeronautical information manual, lights along a straight path can easily be mistaken for runway lights at night. The pilot’s logbook indicated that he had flown 1 hour at night in the accident airplane in the preceding year. Given the pilot's lack of recent night flying experience, it is possible that he initiated the early descent because he had mistaken the nearby parking lot lights for those of the destination airport.

Postaccident examination of the airplane showed no evidence of preaccident failure or malfunction that would have precluded normal operation.
