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 climbing to cross a remote mountain pass when the airplane's engine lost partial power. The pilot turned the airplane to the left and the engine lost total power and started descending very quickly. The pilot attempted to make a forced landing to a road, but did not make it and landed the airplane in an area of rocks and a ditch. The airplane sustained substantial damage to the wings and fuselage, and a postaccident fire then destroyed the airplane. Plotting temperature and dew point on a carburetor icing probability chart placed the conditions noted at the time of the accident as being probable for serious carburetor icing in cruise or climb power. The pilot stated that he did not use carburetor heat either during the climb, or after the engine lost power.
NTSB Probable Cause
The loss of engine power due to carburetor icing and the pilot's failure to recognize conditions favorable for carburetor icing and apply use of carburetor heat.
