NEW MELLE, MO, USA
N44059
Piper PA-28-151
Shortly after takeoff, the elevator trim traveled to the nose up position. The pilot reported that he had to maintain 15 to 20 pounds of pressure on the control yoke to keep the airplane in a nose level attitude, and he had to hold the yoke about 2 inches from its forward stop. He was unable to rectify the situation, and he elected to make an off airport landing. During the landing, the airplane contacted fence posts, and both wings were separated from the fuselage. Postaccident inspection revealed that the wiring between the electric trim switch and the trim motor had shorted. This resulted in motor activation. The pilot stated the trim switch had been broken for 'years,' but he had never disconnected the wiring between the switch and the motor.
On July 28, 1996, at 1415 central daylight time, a Piper PA-28- 151, N44059, operated by a private pilot collided with a fence during an off airport forced landing in New Melle, Missouri. The pilot stated that he was having trouble controlling the pitch attitude of the airplane which resulted in the forced landing. The airplane was substantially damaged. The pilot was not injured and the passenger received minor injuries. The flight was operating in visual meteorological conditions and no flight plan was filed. The airplane departed Chesterfield, Missouri, at 1400 cdt. The pilot reported that shortly after takeoff the airplane started to nose-up. He reported he applied forward pressure on the control yoke and adjusted the manual trim. The nose of the airplane continued to rise and the pilot suspected a "micro burst" so he applied full power and enriched the mixture. He reported that after 30 seconds, he had to maintain 15 to 20 pounds of pressure on the control yoke to keep the airplane in a nose level attitude. He reported having to hold the yoke approximately 2 inches from its forward stop. The pilot stated he determined that it was not a weather problem so he elected to make an off airport landing. The pilot initiated a descent to a farm field but reported that he was too high and fast to land in the open field. He made a turn to parallel a road. The airplane was landed between two fence posts which resulted in both wings separating from the fuselage. The nose of the airplane contacted a gate. Post accident inspection of the airplane revealed the elevator trim switch wiring shorted causing the trim motor to activate resulting in the trim traveling to the full nose up position. The pilot reported the switch had been broken for "many years" but he had not disconnected the wiring between the motor and the switch.
the pilot's selection of an unsuitable area for an emergency/precautionary landing. Factors relating to the accident were: the pilot's continual operation of the airplane with a known deficiency (broken trim switch); an uncommanded activation of the elevator trim to the nose up position, which resulted from a short in the electrical wiring between a broken trim switch and the trim motor; and fence posts in the selected emergency landing area.
