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 PILOT SAID HE WAS PREPARING FOR A PERSONAL FLIGHT WHEN THE ACCIDENT OCCURRED. HE HAD ACCOMPLISHED HIS CHECKLIST UP TO THE ENGINE START PROCEDURE WHEN THE STARTER SYSTEM APPEARED TO BE MALFUNCTIONING. THE NOSE LANDING GEAR WAS CHOCKED, THE BRAKES WERE NOT SET, THE THROTTLE WAS ABOUT ONE INCH, AND THE ELECTRICAL SWITCHES WERE OFF. HE TURNED THE PROPELLER COUNTER CLOCKWISE, TWO SEPARATE TIMES TO SEE IF ANOTHER PLACE ON THE FLYWHEEL WOULD MAKE A DIFERENCE. ON HIS WAY BACK TO THE CABIN, THE ENGINE COUGHED AND STARTED INADVERTENTLY, JUMPED THE CHOCK AND TAXIED ACROSS THE AIRPORT FASTER THAN HE COULD RUN AND CATCH IT. IT HIT A RUNWAY LIGHT, RAN OVER A CHAIN LINK FENCE, AND HIT TREES BEFORE IT STOPPED. THE AIRPLANE WAS SUBSTANTIALLY DAMAGED. THE STARTER SYSTEM WAS NOT TESTED POST CRASH.
