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.

DURING CRUISE FLIGHT, THE PILOT EXPERIENCED A SLIGHT MISS IN THE ENGINE PRIOR TO A TOTAL LOSS OF POWER. TRYING TO AVOID POWERLINES IN FRONT OF HIM, THE PILOT TURNED THE AIRCRAFT 180 DEGREES INTO THE WIND, BUT WASN'T ABLE TO PICK UP ENOUGH SPEED FOR A GOOD AUTO-ROTATION AND IMPACTED THE GROUND. FURTHER INVESTIGATION FOUND THE IGNITION VIBRATOR, PART NUMBER 10-382780-12, WAS INOPERATIVE, CAUSING THE ENGINE FAILURE. A MECHANIC FILED AND ADJUSTED THE POINTS IN THE VIBRATOR, AND WAS THEN ABLE TO OBTAIN AND PROVIDE SPARK TO THE SPARKPLUGS.
