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 74 YEAR OLD PILOT AND HIS WIFE WERE ON A TRIP TO ATTEND A FUNERAL. A WITNESS, WHO HEARD THE AIRPLANE OVERHEAD, REPORTED THAT IT SOUNDED LOW AND AT LEAST ONE ENGINE WAS OPERATING. HE REPORTED THAT WHEN HE LOOKED UP, THE AIRPLANE WAS IN A DIVE, SPINNING SLOWLY; HOWEVER, THE AIRPLANE DID NOT MAKE A COMPLETE REVOLUTION. RADAR DATA SHOWED THE AIRPLANE IN A LEFT DESCENDING TURN AT APPROXIMATELY 2000 FEET PER MINUTE. THE AIRPLANE IMPACTED THE GROUND ABOUT 3 MILES WEST OF THE AIRPORT IN A NEAR VERTICAL DESCENT, AND MUCH OF THE FORWARD SECTION HAD PENETRATED THE GROUND. THERE WAS A POST-CRASH FIRE. EXAMINATION OF THE AIRPLANE AND VARIOUS ACTUATORS CONFIRMED THAT THE LANDING GEAR WAS RETRACTED, FLAPS WERE EXTENDED 5 DEGREES, ELEVATOR AND AILERON TRIM WERE NEUTRAL, AND THE RUDDER WAS POSITIONED 3 DEGREES LEFT. EXAMINATION OF THE ENGINE CONFIRMED INTERNAL/ROTATIONAL DAMAGE.
