Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

THE PILOT DEPARTED VFR INTO IMC (FOG AND LOW CLOUD CEILINGS PRIOR TO RECEIVING HIS IFR CLEARANCE. THE AIRPLANE WAS AIRBORNE APPROXIMATELY 6 MINUTES BEFORE IT COLLIDED WITH TREES AND THE GROUND. THE INVESTIGATION REVEALED THE PILOT AND PASSENGERS HAD ATTENDED A FUNERAL THE DAY BEFORE THE ACCIDENT. ADDITIONALLY, BENZOYLECGONINE [COCAINE METABOLITES] LEVELS OF 0.101 UG/ML IN THE BLOOD AND 0.629 IN THE URINE WERE REVEALED IN THE PILOT'S TOXICOLOGICAL SAMPLES. A BENZOYLECGONINE LEVEL OF 0.906 UG/ML IN THE BLOOD WAS REVEALED IN THE TOXICOLOGY SAMPLE FOR THE PILOT'S WIFE. A HUMAN PERFORMANCE LEVEL STUDY CONDUCTED BY THE SAFETY BOARD REVEALED THAT IT IS 'POSSIBLE THAT THE COCAINE USAGE (BY THE PILOT) EXACERBATED FEELINGS OF EUPHORIA AND INCREASED THE LIKELIHOOD OF A PRIOR DECISION TO TAKEOFF WITHOUT AN IFR CLEARANCE AT A TIME WHEN HIS CAPABILITIES WERE SIGNIFICANTLY COMPROMISED.'
NTSB Probable Cause
THE PILOT'S LOSS OF SITUATIONAL AWARENESS/DISORIENTATION DUE TO THE INFLUENCES OF COCAINE, WHICH RESULTED IN THE LOSS OF AIRPLANE CONTROL IN INSTRUMENT METEOROLOGICAL CONDITIONS. FACTORS RELATED TO THE ACCIDENT WERE: PSYCHOLOGICAL IMPAIRMENT, FATIGUE AND ANXIETY.
