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

While on a cross country flight the pilot recognized that he had been using the wrong road to navigate to his destination. He decided to turn around and return to the departure airport. The pilot reported that he was concerned with the approaching night and decreasing light condition. As the amount of light continued to decrease he elected to make a precautionary landing on a road prior to reaching the departure airport. The pilot stated that either during the landing or taxi the underside of the wing was damaged by contact with a road marker. Further damage to the wing caused by contacting additional road markers occurred when the pilot taxied off the road to park the airplane and again when repositioning the airplane. The pilot reported that there were no known mechanical malfunctions or failures with the aircraft prior to the accident.
