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.

POSTACCIDENT EXAMINATION DISCLOSED 'A MEASURABLE AMOUNT OF FUEL' IN BOTH TANKS, BUT NO FUEL IN THE CARBURETOR BOWL OR FUEL PUMP.
NTSB Probable Cause
FUEL STARVATION FOR UNDETERMINED REASONS, AND THE PILOT'S DELAY IN FLARING THE AIRPLANE. A FACTOR WAS: THE PILOT'S TOTAL LACK OF EXPERIENCE.
