What happened
While performing an aerial application spray run, the pilot began executing a left turn and experienced the onset of a stall buffet. The flight path was characterized by nearby high terrain and power lines. During the maneuver, the pilot lost visual contact with the power lines. To avoid a collision with these utility lines, the pilot elected to maintain the left-hand turn despite the presence of high terrain in the intended direction of travel.
As the turn continued, the aircraft's airspeed and altitude both experienced a steady decay. The uninjured pilot was unable to recover the flight path before the airplane struck the ground at minimum airspeed with the wings in a level position. Following the impact, a postcrash fire ignited and completely consumed the aircraft.
