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.

IT SLID 96 FT & CAME TO REST ABOUT 175 FT EAST OF THE RWY. THE BROKEN CARBURETOR WAS REMOVED & DISASSEMBLED. NO PREIMPACT PART FAILURE OR NOTICEABLE CONTAMINATION WAS FOUND. THE ENG WAS OPERATIONALLY CHECKED; IT STARTED & OPERATED WITH NO PROBLEMS THAT WOULD HAVE CAUSED THE ACDNT. THE TEMP & DEW POINT WERE 36 & 27 DEG, RESPECTIVELY. ACCORDING TO CARB ICE CHARTS, CONDITIONS WERE CONDUCIVE TO CARBURETOR ICE. THE ACDNT OCCURRED AFTER THE PLT HAD INITIATED AN INTERSECTION TAKEOFF WITH ABOUT 1960 FT OF RWY REMAINING.
NTSB Probable Cause
CARBURETOR ICE DUE TO THE PILOT'S IMPROPER USE OF POWERPLANT CONTROLS; AND FAILURE OF THE PILOT TO MAINTAIN ADEQUATE AIRSPEED, WHILE MANEUVERING (TURNING LEFT), WHICH RESULTED IN AN INADVERTENT STALL. FACTORS RELATED TO THE ACCIDENT WERE: FAILURE OF THE PILOT TO USE ALL AVAILABLE RUNWAY, AND CARBURETOR ICING CONDITIONS.
