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.

AT 1444 THE PILOT REQUESTED A DEVIATION FOR WEATHER. AT 1510 THE PILOT ACKNOWLEDGED A REQUESTED CLEARANCE TO DESCEND FROM 10,000 TO 6,000 FEET. THERE WERE NO ADDITIONAL TRANSMISSIONS RECEIVED. THE AIRPLANE DESCENDED ON A SOUTHERLY TRACK AT AN AVERAGE AND MAXIMUM RATE OF DESCENT OF 5,137 AND 8,250 FPM RESPECTIVELY. GROUND SPEED AVERAGED 160 MPH. IMPACT OCCURRED IN A WINGS LEVEL ATTITUDE ABOUT 20 DEG NOSE LOW. THERE WERE THUNDERSTORMS IN THE AREA WITH LIGHTNING, HEAVY RAIN, HIGH WINDS, AND CLOUD TOPS TO 45,000 FEET. NUMEROUS BOTTLES OF INSULIN, SYRINGES WITH NEEDLES, AND A DIABETIC TEST KIT WERE FOUND IN THE PILOT'S BAGGAGE. THE COPILOT'S TOXICOLOGY EXAM REVEALED SIGNIFICANT AMOUNTS OF PHENOBARBITAL, A CONTROLLED SUBSTANCE. THE COPILOT WAS NOT INSTRUMENT RATED. AUTOPSIES OF BOTH PILOTS IDENTIFIED A LACK OF HAND OR FEET INJURIES.
NTSB Probable Cause
THE PILOT-IN-COMMAND FAILED TO MAINTAIN CONTROL OF THE AIRPLANE WHILE FLYING IN SEVERE WEATHER AND INSTRUMENT METEOROLOGICAL CONDITIONS. THE ADVERSE WEATHER CONDITIONS WERE A FACTOR.
