## Analysis

THE 74 YEAR OLD PILOT AND HIS WIFE WERE ON A TRIP TO ATTEND A FUNERAL.  A WITNESS, WHO HEARD THE AIRPLANE OVERHEAD, REPORTED THAT IT SOUNDED LOW AND AT LEAST ONE ENGINE WAS OPERATING.  HE REPORTED THAT WHEN HE LOOKED UP, THE AIRPLANE WAS IN A DIVE, SPINNING SLOWLY; HOWEVER, THE AIRPLANE DID NOT MAKE A COMPLETE REVOLUTION.  RADAR DATA SHOWED THE AIRPLANE IN A LEFT DESCENDING TURN AT APPROXIMATELY 2000 FEET PER MINUTE.  THE AIRPLANE IMPACTED THE GROUND ABOUT 3 MILES WEST OF THE AIRPORT IN A NEAR VERTICAL DESCENT, AND MUCH OF THE FORWARD SECTION HAD PENETRATED THE GROUND.  THERE WAS A POST-CRASH FIRE.  EXAMINATION OF THE AIRPLANE AND VARIOUS ACTUATORS CONFIRMED THAT THE LANDING GEAR WAS RETRACTED, FLAPS WERE EXTENDED 5 DEGREES, ELEVATOR AND AILERON TRIM WERE NEUTRAL, AND THE RUDDER WAS POSITIONED 3 DEGREES LEFT.  EXAMINATION OF THE ENGINE CONFIRMED INTERNAL/ROTATIONAL DAMAGE.
