Analysis

The pilot and his wife departed wichita, Kansas with a destination of phoenix, Arizona. Eight minutes after takeoff, while in a climb to 15,000 feet, the passenger contacted departure control and communicated that she thought that her husband might be dead. While departure control was getting a pilot to assist in the situation, the passenger, who was not a pilot attempted to fly the aircraft. A witness reported a rapid series of climbs and descents just before both horizontal stabilizers and the rudder separated from the aircraft. The aircraft then entered a spin terminating with ground impact. The aircraft was consumed by a post-crash fire.
