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 CERTIFICATED PRIVATE PILOT, THE SOLE OCCUPANT, WAS DEPARTING THE AIRPORT ON A PERSONAL FLIGHT IN THE LOCAL AREA. THE ENGINE BEGAN TO SPUTTER AND LOSE POWER SHORTLY AFTER TAKEOFF AT ABOUT 200 FT AGL. THE PILOT SELECTED AN EMERGENCY LANDING AREA ON A ROAD AT THE DEPARTURE END OF THE RUNWAY. DUE TO POWER LINES ACROSS THE INTENDED LANDING AREA, THE PILOT SELECTED A ROAD PARALLELING AN IRRIGATION DITCH. AFTER CLEARING THE POWER LINES, THE AIRPLANE TOUCHED DOWN ON THE ROAD. DURING THE LANDING ROLL, THE LEFT WING STRUCK A SIGN, CAUSING THE AIRPLANE TO SWERVE INTO THE IRRIGATION DITCH. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED AND THE PILOT RECEIVED MINOR INJURIES. A POST ACCIDENT EXAMINATION OF THE ENGINE REVEALED THAT TWO CYLINDERS HAD LITTLE OR NO COMPRESSION. BOTH CYLINDERS HAD VALVES STUCK IN THE OPEN POSITION.
NTSB Probable Cause
