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
CEN11CA231
The pilot reported that he was landing his helicopter. He transitioned to a hover at about three feet above the ground. The helicopter encountered a sudden gust of wind that blew the helicopter forward and down. The left skid impacted the ground and the helicopter turned to the right and rolled over onto its left side. The helicopter sustained substantial damage to its fuselage and tailcone. The recorded wind conditions indicated gusts from 15 knots to 19 knots. The pilot reported that there were no preimpact mechanical malfunctions with the helicopter.
NTSB Probable Cause
The pilot's inadequate compensation for gusty crosswinds during takeoff, which resulted in a loss of directional control.
