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
CEN25LA143
The pilot departed on an aerial application flight in the helicopter to continue spraying a field with herbicide. The pilot stated that he became preoccupied with touching up areas, which took longer than expected. While flying across the field to begin the next spray pass, the engine experienced a total loss of power, and he immediately knew that it was due to fuel exhaustion. The pilot performed an autorotation and landed hard, which resulted in substantial damage to the main rotor blades and the tailboom. The pilot stated that after the landing, he checked the helicopter fuel tank, and it was empty. There were no mechanical malfunctions or failures of the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot’s improper fuel planning and fuel management, which resulted in a total loss of engine power due to fuel exhaustion and subsequent impact with terrain during an autorotation.
