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 unoccupied airplane nosed over in a cornfield shortly after the pilot hand-propped the engine. The pilot reported that he had chocked both main landing gear, but there was no one at the aircraft controls during the engine start. Upon engine startup, the engine rpm "increased rapidly" before he had enough time to enter the airplane. The airplane reportedly "climbed over the chocks and started moving" and then traversed into a corn field before nosing over. The pilot reported that the accident could have been prevented if he had secured the tailwheel with a tie-down for engine start.
NTSB Probable Cause
The pilot intentionally leaving the airplane unoccupied during the engine start, which resulted in the unoccupied airplane traversing into a cornfield. A factor was the rough/uneven cornfield.
