Aircraft Accident/Incident Report

San Luis Obispo, California 93401
Friday, December 30, 1994 21:30 PST

NTSB Narrative Summary Released at Completion of Accident

THE ACCIDENT SITE IS ON THE SOUTH FACE OF A MOUNTAIN AT 3,000 FEET MSL. THE MOUNTAIN IS PART OF THE COASTAL MOUNTAIN RANGE WHICH SEPARATES SAN LUIS OBISPO FROM THE GREATER SAN JOAQUIN VALLEY, WHERE THE PILOT'S DESTINATION IS LOCATED. CEILINGS IN THE AREA WERE MEASURED BETWEEN 2,600 AND 2,300 FEET. THE NON INSTRUMENT-RATED PILOT RECEIVED TWO WEATHER BRIEFINGS PRIOR TO DEPARTURE AND WAS ADVISED THAT MARGINAL VFR CONDITIONS EXISTED WITH SAN LUIS OBISPO REPORTING A MEASURED CEILING OF 3,500 BROKEN AND VISIBILITY 10 MILES. THE BRIEFER ADDED AN OBSERVATION FROM AN AIRPORT ABOUT 20 MILES SOUTH OF SAN LUIS OBISPO, WHICH HAD CEILINGS OF 3,000 FEET OVERCAST. THE BRIEFER THEN PROVIDED THE PILOT WITH THE SAN JOAQUIN VALLEY OBSERVATIONS INDICATING CLEAR CONDITIONS BELOW 12,000 FEET. THE PILOT RESPONDED, 'THAT'S GOOD ENOUGH FOR US'. THE PILOT STATED HIS INTENDED CRUISE ALTITUDE AS, 'ABOUT FORTY FIVE HUNDRED FEET ONCE WE GET PAST THESE CLOUDS'. THE BURNED AND FRAGMENTED WRECKAGE WAS SPREAD OVER 260 FEET ON A 10-DEGREE DESCENDING PATH ON THE MOUNTAINSIDE. NO MECHANICAL FAILURES WERE IDENTIFIED IN THE WRECKAGE EXAMINATION.

NTSB Probable Cause Narrative

the pilot's intentional flight into an area of known marginal weather conditions during a night cross-country flight and the flight's subsequent inadvertent entry into instrument meteorological conditions at an altitude insufficient to remain clear of the surrounding terrain.
