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 making a personal cross-country flight under Title 14, CFR Part 91. He said he was circling an off airport landing site at a reduced power setting, and when he applied throttle the engine quit. The pilot reported that during taxi for takeoff prior to the flight, the airplane's engine had carburetor ice, and he felt that this was what caused the engine to quit since he had not applied carburetor heat when he reduced power. The airplane made an emergency descent and impacted on muskeg. During the landing, the main landing gear attachments and left wing were damaged. The pilot indicated that there were no known mechanical problems with the airplane prior to the accident.
