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

While conducting an instructional flight, the flight instructor reported that he and the student pilot were practicing straight-in autorotation approaches in the helicopter with a power recovery. The helicopter was configured with a throttle control switch rather than a twistable throttle control. During the fifth autorotation approach, the flight instructor forgot to move the throttle control from “Idle” to “Fly” prior to flaring the helicopter. The helicopter descended and landed hard on the runway. During the hard landing, the helicopter sustained substantial damage to the tailboom. The flight instructor reported that there were no mechanical malfunctions or failures that contributed to the accident.
