THE PLT AND HIS TWO PAX HAD JUST ARRIVED AT THE JACKSON HOLE AIRPORT (JAX) APPROXIMATELY 30 MINUTES PRIOR TO THE ACCIDENT. THE PLT DROPPED OFF HIS PAX AND STEPPED INTO OPERATIONS FOR A SHORT BREAK. HE THEN RETURNED TO THE ACFT BY HIMSELF FOR A RETURN FLT TO CALIFORNIA. IT WAS A VERY DARK NIGHT WITH A 2000 FT OVERCAST AND NO VISIBLE HORIZON. THE PLT HAD DEPARTED REDDING, CA AT 1357 HOURS AND HAD BEEN ON CONTINOUS FLT DUTY FROM THAT TIME UNTIL THE TIME OF THE ACCIDENT. A WITNESS STATED THE PLT SEEMED TO BE TIRED AND HUNGRY. THE ACFT WAS OBSERVED MAKING A NORMAL NIGHT TAKEOFF. WITNESSES STATED THAT AS THE ACFT TURNED FROM CROSSWIND TO DOWNWIND IT APPEARED THAT THE PLT HAD TROUBLE CONTROLLING THE ACFT. AFTER THE ACFT MADE A FEW EXTREME UP AND DOWN MANEUVERS, IT APPEARED TO PROCEED TO THE EAST. THE NEXT TIME THE ACFT WAS OBSERVED, IT WAS AGAIN CLIMBING AND DESCENDING RAPIDLY AND SUBSEQUENTLY IMPACTED THE GROUND IN A VERTICAL DIVE.
