THE CERTIFICATED NON-INSTRUMENT RATED COMMERCIAL PILOT AND THREE PASSENGERS DEPARTED ON A RETURN PORTION OF A CROSS COUNTRY FLIGHT OVER HIGH MOUNTAINOUS TERRAIN. THE PILOT OBTAINED A WEATHER BRIEFING FOR THE FIRST PORTION OF THE FLIGHT, BUT NOT FOR THE RETURN FLIGHT. A WITNESS REPORTED THAT THE MOUNTAIN TOPS IN THE AREA OF THE ACCIDENT WERE OBSCURED BY CLOUDS. WHILE IN A LEFT TURN, THE AIRPLANE STRUCK SNOW COVERED TERRAIN AT THE END OF A BOWL SHAPED CANYON, ABOUT 400 FEET BELOW THE TOP OF A RIDGE LINE. NO MECHANICAL MALFUNCTIONS WERE FOUND WITH THE AIRPLANE.
Probable Cause: The pilot's inadequate weather evaluation; inadequate in-flight planning and decision making; and the pilot's continued VFR flight into instrument meteorological conditions.
