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.

CEN15CA348
The pilot flew over the field to be sprayed looking for obstacles. Seeing none, he commenced spraying and collided with power lines. The pilot said the power lines were only 13 feet off the ground and were green in color that blended in with the background crops. The helicopter's canopy contacted the power lines, then the lines slid beneath the helicopter and caught the skids. The helicopter nosed over and impacted terrain.
NTSB Probable Cause
The pilot's inability to see and avoid power lines that were low to the ground and a green color that blended with the background crops.
