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 certified flight instructor (CFI) stated that during a local training flight, the helicopter was at a hover and he reduced power to simulate an engine failure. He said that upon ground contact, the aft portion of helicopter's left skid sank into the mud, the helicopter began to roll to the left, and he attempted corrective action for a dynamic rollover. However, the helicopter rolled over on to its left side resulting in substantial damage to the main rotor blades and fuselage. The CFI and student pilot both stated that there were no mechanical malfunctions with the helicopter prior to the accident.

NTSB Probable Cause

The flight instructor's selection of an unsuitable landing site to practice autorotations, which resulted in an inadvertent dynamic rollover during touchdown.
