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.

AN INVESTIGATION REVEALED THAT THE FUEL SYSTEM WAS CONTAMINATED WITH DEBRIS FROM THE DETERIORATING CARBURETOR ACCELERATOR PUMP. A FUEL SAMPLE WAS TAKEN FOR AN ANALYSIS, WHICH REVEALED THE FUEL WAS A MIXTURE OF AVGAS & AUTOMOTIVE GASOLINE.
NTSB Probable Cause
FUEL CONTAMINATION FROM A DETERIORATING PART IN THE CARBURETOR. THE TREES AND IMPROPER MAINTENANCE/SERVICING OF THE AIRCRAFT WERE PROBABLE CONTRIBUTING FACTORS.
