## 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.
