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.

ACCORDING TO THE PILOT, THE ENGINE STOPPED RUNNING DURING CRUISE FLIGHT. FUEL WAS AVAILABLE, BUT THE ENGINE COULD NOT BE RESTARTED. DURING AN EMERGENCY WHEELS-UP LANDING ON ROUGH TERRAIN, THE AIRPLANE SLID INTO A TREE. EXAMINATION OF THE FUEL SYSTEM REVEALED THAT THE FUEL PRESSURE REGULATOR WAS ADJUSTED TO A MINIMUM PRESSURE SETTING. ABOUT 4 PSI OF FUEL PRESSURE WAS AVAILABLE; A MINIMUM OF 10 PSI WAS NEEDED FOR THE PRESSURE CARBURETOR TO OPERATE. WITH THE LINE FROM THE ENGINE DRIVEN FUEL PUMP TO THE FUEL PRESSURE REGULATOR BLOCKED (FOR A TEST), THE FUEL PRESSURE WOULD READ IN EXCESS OF 15 PSI. NO REASON WAS FOUND FOR THE IMPROPER ADJUSTMENT.
NTSB Probable Cause
IMPROPER ADJUSTMENT OF THE FUEL PRESSURE REGULATOR WHICH PRODUCED AN INADEQUATE FUEL FLOW AND SUBSEQUENT FUEL STARVATION. FACTORS RELATED TO THE ACCIDENT WERE: THE ROUGH TERRAIN AND TREES IN THE EMERGENCY LANDING AREA.
