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, while lifting off from a landing deck on top of an industrial truck, the helicopter's right rear skid hooked into an opening on the deck. The helicopter dynamically rolled right and impacted the ground. The helicopter sustained substantial damage to the main and tail rotor systems, fuselage, and empennage. 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 improper cyclic input during liftoff from a landing deck, which resulted in the right skid hooking onto an opening on the landing deck and a subsequent dynamic rollover.
