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 reported that, while maneuvering to apply chemical to a field at low altitude, the top of the vertical stabilizer struck a set of power lines. The pilot reported that “the rudder was hammed and [he] had no rudder control.” The pilot made a forced landing in a wheat field. The airplane sustained substantial damage to the vertical stabilizer. The pilot reported no preaccident failures or malfunctions with the airplane before the collision with the power lines that would have precluded normal operations.
NTSB Probable Cause
The pilot’s failure to maintain clearance from the power lines during a low-level application pass.
