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 said that he was moving Christmas trees during harvesting operations. He said that one of the two slings holding the load failed, and as the trees fell to the ground, the second sling "popped" into his rotor head. The pilot said that both the cyclic and collective were severed, and he lost all flight control. An autorotation was not possible and the helicopter fell to the ground and came to rest on its right side.

NTSB Probable Cause

A severing of the helicopter's cyclic and collective rods by one of the load lifting slings following the failure of the other sling. A contributing factor was the hard landing due to the fact that an autorotation was not possible.
