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 amateur-built helicopter was substantially damaged when it caught a skid and rolled over during landing. The pilot stated that he originally landed at the accident airport as an intermediate fuel stop. After fueling, the pilot and passenger planned to continue the trip. The pilot stated that on takeoff, the helicopter had not obtained translational lift before he flew from the paved ramp area toward an agricultural field and "lost [the] cushion of air." He made a "sharp" 180-degree turn in an attempt to return to the ramp area; however, the "passenger side skid hooked [the] edge of [the] tarmac" and the helicopter rolled onto its side. He noted that he had not allowed for the temperature increase from the time of his takeoff on the previous flight until the accident takeoff. He added that he should have reduced the fuel load and not flown with a passenger. He stated that there were no failures or malfunctions associated with the helicopter.

NTSB Probable Cause

The pilot's failure to maintain clearance from the airport ramp area during the return for landing, which resulted in the landing skid dragging on the edge of the pavement and causing the helicopter to roll over.
