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.

DFW06CA213

The 1,365 hour single engine airplane rated pilot, who had accumulated 33 hours of flight instruction in a helicopter lost control of the helicopter while attempting to take off during his first solo flight. The pilot was attempting to take off on the parallel taxiway to runway 35 on a heading of 350 degrees when he lost control of the aircraft as the helicopter lifted off the ground. The pilot reported in the Pilot/Operator Aircraft Accident/Incident Report (NTSB Form 6120.1), that the "helicopter became airborne suddenly with much less collective input than I expected." The helicopter began to roll to the right and the pilot then overcorrected to the left with cyclic input and lowered the collective. The helicopter's left skid made contact with the ground first and the helicopter entered a dynamic roll to the left until the main rotor contacted the ground, and the helicopter came to rest on its left side. Prior to the solo flight, the pilot and his instructor discussed the changes in the flight characteristics concerning single occupancy in the helicopter and the procedures for the flight. The pilot was not injured. Weather reported by the pilot was overcast skies, 10 miles visibility with winds from 340 degrees at 10 knots, and a density altitude of approximately 948 feet.

NTSB Probable Cause

The pilot's failure to maintain control of the helicopter following an encounter with dynamic rollover.
