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
CEN11CA524
According to the pilot, he was landing the helicopter on a helicopter cart when its skid got caught on the cart and the helicopter subsequently rolled over. The pilot reported there were no mechanical malfunctions with the helicopter during the flight, and substantial damage was sustained to the helicopter tailboom when it rolled. Dynamic rollover is the tendency of a helicopter to continue rolling when the critical angle is exceeded, if one skid is on the ground, and the helicopter is pivoting around that point. Dynamic rollover is possible when a skid is caught by a projection on the surface or when landing on a slope.
NTSB Probable Cause
The pilot's failure to maintain adequate skid clearance from the helicopter cart during landing, resulting in a dynamic rollover.
