Analysis

During an aerial application flight at night, the airplane's vertical stabilizer collided with a transmission wire. Subsequently, the vertical stabilizer & rudder were dislocated & directional control was lost. Realizing he had lost directional control, the pilot allowed the acft to immediately touchdown & land. While on the landing roll, the acft hit a 'water line.'
