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

NTSB narrative

The pilot departed under visual flight rules (VFR) and was flying under a cloud layer at an altitude that was approximately 500-800 feet above the trees. When the VFR conditions worsened, he "stayed on instruments," at an altitude of 3,500 feet msl, and shortly thereafter, the airplane impacted terrain, approximately 500 feet from the summit of a 2,937-foot mountain. When asked what caused the accident, the pilot stated, "Controlled flight into terrain." Witnesses reported at the time of the accident, the mountain was obscured by a cloud layer from its summit, down to about 2,000 feet, and the lateral visibility was approximately 200 feet. Examination of the airplane revealed no pre-impact mechanical deficiencies. The pilot received his instrument rating 5 years prior to the accident, and had logged a total of 5.4 hours of instrument time during 4 flights since then. The pilot's most recent instrument experience was 3 years prior to the accident, when he logged 0.5 hours of actual instrument time.

Probable cause

The pilot's continued VFR flight into IMC conditions, and his failure to maintain terrain clearance, which resulted in a controlled flight into terrain. Factors in the accident were the low cloud ceiling and the pilot's lack of recent instrument time.

  • 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: investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
