What happened
During a practice single-engine approach to a 2,100-foot grass runway, the pilot intentionally shut down the left engine while on the downwind leg. While preparing for landing, the pilot observed another aircraft taking off in the opposite direction.
To avoid the departing airplane, the pilot executed a single-engine go-around and sidestepped to the right of the runway. During this maneuver, the flaps were retracted, but the landing gear remained in the down position. As the aircraft was unable to maintain a positive rate of climb, the pilot initiated a left turn toward a clear area.
Upon completing the turn, the left wing and the landing gear struck power lines. The impact pulled the aircraft to the ground approximately 300 feet west of the runway. The pilot was not injured in the accident, and no mechanical malfunctions were reported.
