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.

AFTER IMPACTING THE TOP OF THE TREES, THE HELICOPTER FELL TO THE GROUND. AFTER THE CRASH IT WAS FOUND THAT A SHORT IN THE FUEL QUANTITY TRANSMITTER UNIT HAD CAUSED THE FUEL GAUGE TO READ 20 GALLONS, WHEN THE TANK ACTUALLY HAD ABOUT ONE CUP OF FUEL REMAINING.
