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.

WHILE ON INITIAL CLIMB, THE LEFT ENGINE QUIT. THE PILOT MADE A GEAR UP LANDING IN A FIELD, COMING TO REST ONE-HALF MILE FROM THE END OF THE RUNWAY. THE INVESTIGATION SHOWED THAT THE LEFT PROPELLER HAD NOT BEEN FEATHERED, BUT THE RIGHT PROPELLER SHOWED EVIDENCE OF BEING FEATHERED PRIOR TO IMPACT. AN ENGINE RUN OF THE LEFT ENGINE SHOWED THE UNMETERED FUEL PRESSURE WAS SET TOO HIGH AT IDLE, RESULTING IN ROUGH RUNNING AND ENGINE STOPPAGE. EVIDENCE FROM THE AIRCRAFT LEFT ENGINE LOGBOOK INDICATED A HISTORY OF HARD STARTING, MIXTURE RELATED PROBLEMS AND ROUGH RUNNING. THE OPERATOR HAD KNOWLEDGE OF THESE FAULTS. HE TOLD THE PILOT TO START THE LEFT ENGINE WITH THE MIXTURE LEVER RETARTED TO NEAR IDLE CUTOFF.
NTSB Probable Cause
THE LOSS OF POWER ON ONE ENGINE DUE TO EXCESSIVE FUEL PRESSURE AND THE PILOT'S FEATHERING OF THE WRONG PROPELLER. FACTOR(S) WERE: OPERATION OF AIRCRAFT WITH KNOWN DEFICIENCIES BY PILOT AND OPERATOR.
