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 22-hour helicopter student pilot lost control of the single-engine helicopter while performing a hovering maneuver during a solo training flight. The pilot added that while hovering at a skid height of 10-feet above the ground, the helicopter encountered a phenomena known as loss of tail rotor effectiveness (LTE). The helicopter entered an uncontrolled hard spin to the right. The pilot responded by lowering the collective and the helicopter landed hard. The helicopter sustained structural damage to the right strut, the tail rotor drive shafts, and the right horizontal stabilizer. The pilot egressed from the helicopter normally and sustained no injuries. The winds at the time of the mishap were reported from 210 degrees at 6 knots.

NTSB Probable Cause

The loss of control as result of loss of tail rotor effectiveness.
