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 helicopter instructor reported that, during the approach to land, about 5 ft above the ground, the student pilot overcorrected and moved the cyclic "back hard and slightly right." The right rear skid contacted the ground, and the helicopter rolled to the right. The main rotor blades struck the ground, and the helicopter came to rest on its right side. The student reported that he believed the skid strike and unusual attitude were caused by his inexperience. The helicopter sustained substantial damage to the main rotor blades, the fuselage, and the tailboom. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
