The pilot, during a night flight, was unsuccessful at locating the destination, Tradewater Airport (8M7), so he deviated to and landed at Princeton-Caldwell County Airport. There he became concerned about his airplane being unsecured at an unattended airport and the threat of inclement weather forecasted to occur overnight. He arranged for a friend to use the headlights of a car to illuminate the grass strip at 8M7, so the pilot could return and land. The pilot flew back, circled the airport, spotted the headlights, and began the approach. According to the pilot, "Just prior to crossing the threshold markers, I saw the roof of the automobile in the beam of my landing light, and felt contact and sensed the airplane tumbling and a second contact when the airplane came to rest upside down." According to the FAA, the main wheel struck the back window of the car. The pilot said the accident could have been prevented if he had not been so anxious to fly the airplane to 8M7 where it would be hangared.
