Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
En route · cruise
First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
In flight collision with terrain/water
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Visual flight rules (VFR) flight into instrument meteorological conditions (IMC)
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Destroyed

NTSB narrative

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.

Probable cause

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.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1994-12-31.
