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.

REPORTEDLY, HE CHANGED THE MIXTURE SETTING AND APPLIED CARBURETOR HEAT IN AN ATTEMPT TO RESTORE FULL POWER, BUT THE ENGINE POWER REDUCTION CONTINUED TO A POINT WHERE POWERED FLIGHT WAS NO LONGER POSSIBLE. A FORCED LANDING WAS MADE TO AN OPEN FIELD. DURING THE GROUND ROLL OUT, THE AIRPLANE ROLLED THROUGH A FENCE, CROSSED A ROAD, AND FLIPPED INVERTED AFTER COLLIDING WITH A SECOND FENCE.
