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 TWIN ENGINE AIRPLANE WAS ON FINAL APPROACH AND THE PILOT NOTED THAT THE RIGHT ENGINE WOULD NOT GO BELOW HALF POWER. THE AIRPLANE WAS LANDED AND THE PILOT ELECTED TO ABORT. AFTER ROTATION, THE RIGHT ENGINE FAILED. THE PILOT RAISED THE LANDING GEAR AND ATTEMPETD TO FLY AROUND THE TRAFFIC PATTERN ON ONE ENGINE. THE RIGHT PROPELLER WOULD NOT FEATHER AND THE AIRPLANE WOULD NOT CLIMB. THE PILOT AVOIDED SEVERAL TREE LINES BEFORE DESCENDING GEAR UP INTO A FIELD OF CROPS AND SLID ONTO A ROAD. EXAMINATION OF THE AIRPLANE REVEALED THAT THE CASTLE NUT HAD BACKED OFF THE RIGHT ENGINE'S CARBURETOR AND THE LINKAGE DISCONNECTED. THERE WAS NO COTTER PIN INSTALLED.
NTSB Probable Cause
ENGINE FAILURE AS A RESULT OF IMPROPER MAINTENANCE AND FAILURE OF THE PROPELLER FEATHERING SYSTEM FOR AN UNDETERMINED REASON. FACTORS WERE AIRCRAFT POOR CLIMB PERFORMANCE AS RESULTED OF THE UNFEATHERED PROPELLER AND OBSTRUCTIONS WHICH PREVENTED A RETURN TO THE AIRPORT.
