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.

Full Narrative
On August 9, 1995, at 0500 hours mountain standard time, the pilot of a Mielec WSK-PZL-M-18 aircraft, N6657C, experienced a power surge and subsequent loss of engine power during a 14 CFR Part 137 aerial application flight near Sacaton, Arizona. The pilot made a forced landing in a riverbed. The aircraft was substantially damaged and the pilot was not injured. Visual meteorological conditions existed at the time. The aircraft departed from a local agricultural strip at 0415 hours. The inspection of the engine by the FAA revealed a decoupling of the accessory drive that runs the high pressure engine-driven fuel pump.
