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 helicopter rolled over while hover taxiing into position for a takeoff. The pilot was practicing takeoffs and landings in a dry river bed. Following a landing, the pilot was repositioning the helicopter to the right when the right skid contacted wet sand and dug in. The helicopter began tipping to the right and the pilot responded by applying left cyclic. The pilot told Federal Aviation Administration inspectors that he then made the mistake of increasing the collective in an attempt to clear the obstruction. The helicopter rolled over to the right and sustained substantial damage.

NTSB Probable Cause

the pilot's improper use of the collective control while attempting to free the right skid, which induced a dynamic rollover.
