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 September 29, 1994, about 1715 central daylight time, N48572, a Grumman G-164B, registered to Barham Brothers Inc. crashed near Greenwood, Mississippi, while on a 14 CFR Part 137 aerial application flight. Visual meteorological conditions prevailed at the time and no flight plan was filed for the local flight. The airplane was substantially damaged and the pilot reported no injuries. The flight had originated from a local dirt road about 15 minutes earlier. The pilot stated that when he added power the rpm increased but the manifold pressure did not. He dumped his chemical load and attempted a forced landing to a plowed field. During landing roll the airplane flipped inverted. Examination of the engine by local FAA personnel revealed that the supercharger shaft and bearing had failed.
