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.

CEN11CA010
The pilot reported that he departed from his private airstrip with a passenger for a local flight. Upon returning for landing, his neighbor was operating a combine harvester in a soybean field near the runway threshold. The pilot extended his traffic pattern to allow time for the machine to move out of the runway approach path. However, upon turning back toward the runway, the machine had not moved as far as he had expected. The pilot stated that at that point the airplane struck a power line. It subsequently came to rest upside down and was destroyed during the accident sequence. The pilot stated that there were no failures or malfunctions associated with the airplane prior to the accident.
