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 WAS OPERATING THE AIRCRAFT ON AN INSTRUCTIONAL FLIGHT WHEN ENVIRONMENTAL CONDITIONS WERE FAVORABLE FOR MODERATE ICING IN CARBURETED POWERPLANTS. WHILE IN CRUISE FLIGHT THE POWERPLANT STARTED TO LOSE RPM AND THE PILOT FAILED TO APPLY CARBURETOR HEAT. HE OPENED AND CLOSED THE THROTTLE IN AN ATTEMPT TO REGAIN OPERATING RPM AND EVENTUALLY APPLIED CARBURETOR HEAT FOR APPROXIMATELY 3 TO 4 SECONDS, TO NO AVAIL. HE EXECUTED A FORCED LANDING TO A FIELD WHERE THE HIGH VEGETATION CAUSED THE AIRCRAFT TO NOSE OVER DURING THE LANDING ROLL.
NTSB Probable Cause
THE PILOT'S IMPROPER USE OF CARBURETOR HEAT RESULTING IN A PARTIAL, NON-MECHANICAL POWER LOSS FROM CARBURETOR ICING CONDITIONS.
