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.

SEA08CA019
The flight instructor reported that he and his student were practicing hovering autorotations. After the student successfully performed two hovering autorotations from a height of 2 inches, the flight instructor had the student bring the helicopter to a 1-foot hover. During initiation of the maneuver from this altitude, the student pilot applied full right pedal and began to roll the throttle on, which "immediately resulted in substantial right yaw." The flight instructor corrected by adding left pedal, rolling the throttle off, and lowering the collective. These actions overcorrected for the right yaw and resulted in a left yaw. As the skids touched the ground, the flight instructor fully lowered the collective. The aft cross tube was bent, and the tail boom was wrinkled.
NTSB Probable Cause
The student pilot's improper use of the flight controls while performing a hovering autorotation and the flight instructor's excessive remedial action which resulted in a hard landing.
