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 certified flight instructor (CFI) and student pilot were practicing hovering. The student pilot had 6 hours total flight time, with all of his flight time being accrued in the accident make/model helicopter. During the hover, the right skid contacted the ground and the helicopter rolled onto its right side. The CFI reported that he delayed assuming control of the helicopter and allowed the helicopter to get too low during the maneuver.

NTSB Probable Cause

The student pilot's failure to maintain an adequate drift control and skid clearance from the ground and the CFI's inadequate supervision while hovering, resulting in dynamic rollover.
