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 stated that he was flying down a glacier for an extended period of time at a low power setting without the carburetor heat on. Near the toe of the glacier, he attempted to add power to level the airplane, but the engine did not respond. He stated that their altitude was low and he landed on the glacier moraine, and the airplane nosed over, sustaining substantial damage to the wings and fuselage. The pilot stated that there were no preaccident mechanical anomalies with the airplane that would have precluded normal operation. Based on the temperature and dew point at the time of the accident, the conditions were favorable for serious carburetor icing at descent power.
