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.

THE PILOT REPORTED THAT AT THE END OF A SPRAY RUN, THE ENGINE LOST POWER. HE STATED THAT THE ENGINE RPM DROPPED TO ZERO, THE AIRSPEED WAS ZERO, AND HE ESTABLISHED AN AUTOROTATION. ACCORDING TO THE PILOT, THE HELICOPTER TOUCHED DOWN ON ROUGH HILLY TERRAIN, BOUNCED AND ROLLED OVER ON ITS RIGHT SIDE. LATER, WHEN THE AIRCRAFT WAS RECOVERED, A CRACK WAS FOUND IN THE FUEL SERVO UNIT ADJACENT TO THE MIXTURE ADJUSTMENT. REPORTEDLY, THIS CRACK WOULD HAVE ADMITTED EXCESSIVE AMOUNTS OF AIR INTO THE SERVO UNIT AND WOULD HAVE RESULTED IN A LOSS OF POWER.
