NTSB Narrative Summary Released at Completion of Accident

THE PILOT OBTAINED WEATHER INFORMATION FROM THE TV PRIOR TO DEPARTURE AND USED LORAN AS A MEANS OF NAVIGATION TO HIS DESTINATION. HE SAID HE OVERFLEW THE AIRPORT AND THEN EXTENDED SEVERAL MILES. WHILE MANEUVERING TO RETURN TO THE AIRPORT, THE AIRPLANE FLEW INTO RISING TERRAIN, STRIKING TREES. A WITNESS WHO HEARD THE CRASH DESCRIBED THE WEATHER AS FOGGY AT THE TIME OF THE ACCIDENT WITH VISIBILITY BETWEEN 100 AND 200 FEET. THE PILOT SAID HE WAS MANEUVERING AT 3000 FEET, HOWEVER, HE STRUCK A RIDGE AT APPROXIMATELY 2200 FOOT.
