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 he took off and hovered about 100 feet above the ground when the net gun, which was held by the passenger, accidentally discharged. The helicopter started to vibrate; the pilot landed the helicopter uneventfully and shut it down. Postaccident examination of the helicopter revealed the net went through one of the main rotor blades and damaged the others. There were no reported preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The passenger's accidental discharge of the net gun which resulted in the net going through a main rotor blade.
