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.

NTSB Probable Cause
CARBURETOR ICE. THE PILOT FAILED TO APPLY CARBURETOR HEAT IN A TIMELY AND ADEQUATE MANNER. THIS FAILURE RESULTED IN THE ACCUMULATION OF ICE TO A POINT OF FAILURE OF THE ENGINE WHICH ELIMINATED THE HEAT NECESSARY TO REMOVE THE ICE.
