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 student pilot reported that he was landing the turbine-powered helicopter on a frozen lake covered by 18 to 24 inches of snow. He reported that during the landing flare, in reduced visibility due to blowing snow, the helicopter drifted right and when the skid depth in the snow increased the helicopter rolled over, which resulted in structural damage to the airframe. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter.
