While en route to a field for an aerial pesticide application, the helicopter pitched nose down and impacted the ground. Two roads ran perpendicular to the accident site; one ran east/west, and the other ran north/south. The pilot departed from a service truck in a southwest direction. The destination field was 2 miles southwest of the service truck. As the pilot crossed the east/west road, he made a wide, left turn, traveling northbound. At the intersection of the two roads, the helicopter maneuvered up and over power lines that were parallel to the east/west road. The helicopter turned left about 90 degrees (west), followed by another left turn of 90 degrees (south). The nose suddenly pitched down, and the helicopter impacted the ground. The wreckage site was 1/2 block north from the intersection of the two roads. Post examination of the airframe and engine did not reveal any preimpact anomalies.
Probable Cause: loss of control for undetermined reasons.
