Analysis

The pilot, who was applying fertilizer to a rice field, stated that as he pulled up and initiated a turn to reverse direction on his second pass, the airplane began settling. He said he thought he encountered mechanical turbulence from a nearby tree line and the airplane got behind the power curve. He attempted to recover, however, the airplane continued to settle, struck power lines and impacted in a muddy field.
