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.

NTSB Number
CEN25LA221
During an aerial application of a field, the airplane was in a 20 to 30o descent at 140 kts when its vertical stabilizer struck a power line. The vertical stabilizer and rudder separated from the airplane, which resulted in the airplane’s uncontrolled descent and impact with the ground. The airplane sustained substantial damage to the vertical stabilizer, rudder, fuselage, and both wings. The pilot stated that he knew the location of the power line, but it was pilot error that resulted in the collision with the power line. The pilot stated there were no mechanical malfunctions or failures with the airplane before the accident.
NTSB Probable Cause
The pilot’s failure to maintain clearance with the power lines while maneuvering that resulted in an in-flight collision with the power lines and impact with terrain.
