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.

AFTER RECEIVING A WEATHER BRIEFING AND FUELING THE AIRPLANE, THE PILOT DEPARTED ON A CROSS COUNTRY FLIGHT. THE PILOT STATED THAT ABOUT AN HOUR INTO THE FLIGHT, THE ENGINE 'GRADUALLY LOST RPM' AND HE APPLIED CARBURETOR HEAT 'A LITTLE BIT'. ALL POWER WAS LOST AND HE EXECUTED A FORCED LANDING. THE AIRPLANE TOUCHED DOWN IN A FIELD AND BOUNCED. THE PILOT STATED THAT HE 'PUSHED DOWN ON THE YOKE' TO GET IT BACK ON THE GROUND AND THE AIRPLANE THEN NOSED OVER. AN EXAMINATION OF THE AIRPLANE AND ENGINE DID NOT DISCLOSE ANY MECHANICAL MALFUNCTIONS. ACCORDING TO THE DOT/FAA/CT82/44 PUBLICATION: LIGHT AIRCRAFT PISTON ENGINE CARBURETOR ICE DETECTOR/WARNING DEVICE SENSITIVITY/EFFECTIVENESS, THE PREVAILING TEMPERATURE AND DEWPOINT AT THE TIME OF THE ACCIDENT PRODUCED A PROBABILITY OF CARBURETOR ICING AT GLIDE AND CRUISE POWER.
NTSB Probable Cause
THE PILOT'S IMPROPER USE OF CARBURETOR HEAT CONTROL RESULTING IN A TOTAL LOSS OF ENGINE POWER. FACTORS CONTRIBUTING TO THE ACCIDENT INCLUDE THE EXISTENCE OF WEATHER CONDITIONS CONDUCIVE TO CARBURETOR ICING AND THE ROUGH TERRAIN ON WHICH THE AIRCRAFT WAS LANDED.
