Analysis

The pilot of a C172 flew into a telephone wire, lost control of the airplane and collided with the terrain while executing a simulated forced landing approach to a field about 8 miles west of Rio Vista, CA. The pilot stated that he was showing his passengers simulated forced landing approach to an open field. While in a descent, both of the pilots and the passenger saw a telephone wire in their flight path (at about 75 feet above ground level). The private pilot was unable to avoid the wire. The airplane's main landing gear cleared the wire but, the right side of the horizontal stabilizer caught the wire. The private pilot lost control of the airplane and collided with the terrain. There was no reported mechanical malfunction or failure to the airplane, prior to the accident.
