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
CEN22LA350
The pilot reported that, during an aerial application flight in a helicopter, he mistakenly thought a power pole he had observed during an overflight was the termination point of a powerline. He stated that he failed to notice another power pole that was obscured by trees near a small house and impacted the lines between the poles during a spray pass. The helicopter subsequently impacted terrain. The helicopter sustained substantial damage to the fuselage, tail boom and main rotor blades. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s failure to adequately survey a field for obstructions prior to a low-level aerial application pass, which resulted in an impact with a powerline.
