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
WPR21LA093
The pilot reported that during a practice approach to an off-airport location, he increased the collective and applied left pedal to bring the helicopter to a hover. The helicopter nosed right and continued to rotate as he attempted to stop it by applying left pedal. Subsequently, the helicopter encountered a tail wind situation, and the rate of turn became excessive, as he continued to attempt to arrest the spin. Shortly thereafter, the left skid caught the ground and bent inward, causing the helicopter to roll on its left side. The fuselage and main rotor blades were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The pilot's uncoordinated flight control inputs while entering a hover, which lead to a loss of aircraft control which resulted in the left skid making contact with the ground, causing the helicopter to roll on its side.
