DURING A TELEPHONE INTERVIEW, THE PILOT STATED THAT HE HAD JUST RECOVERED FROM A ONE TURN SPIN AND WAS IN LEVEL FLIGHT WHEN HE FELT THE AIRPLANE PITCH UP. HE ADDED A SMALL AMOUNT OF NOSE DOWN TRIM AND THE AIRPLANE PITCHED DOWN. HE STATED THAT AT THIS POINT 'THINGS DID NOT FEEL RIGHT'. HE PULLED BACK ON THE STICK AND IT DID NOT MOVE WELL, NOR WOULD IT CONTROL THE AIRPLANE. AFTER TRYING TO DETERMINE THE REASON FOR THE PROBLEM AND A ATTEMPT TO TURN TOWARDS A POSSIBLE LANDING AREA, THE PILOT DECIDED TO EGRESS FROM THE AIRPLANE. THE AIRPLANE ENTERED AN UNCONTROLLED DESCENT AND COLLIDED WITH THE TERRAIN. AN EXAMINATION OF THE WRECKAGE WAS CONDUCTED BY FAA INSPECTORS AT THE SCENE OF THE ACCIDENT.
