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.

NTSB Number
ERA22LA236
The private pilot was receiving a checkout in the helicopter from the flight instructor, and they were practicing pick-ups and touchdowns on the non-movement area of the airport. The flight instructor was demonstrating a pick-up to the pilot when the helicopter rolled left (due to a wind gust) and reached an angle where the instructor described that he was unable to recover, resulting in a dynamic rollover. The fuselage and main rotor were substantially damaged during the accident. The pilot reported that there were no mechanical malfunctions or failures of the helicopter that would have precluded normal operation, nor did the flight instructor report any.
NTSB Probable Cause
The flight instructor’s failure to maintain control of the helicopter during the takeoff, which resulted in a dynamic rollover.
