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.

During a flight test of the experimental helicopter, the pilot inadvertently shut off the fuel supply to the engine while flaring to land, approximately 15 feet above the ground. The helicopter impacted the ground tail first, the landing gear cross tubes collapsed and broke at the fuselage attach points, and the main rotor struck the tail boom. Examination of the helicopter revealed that the fuel shut off switch was unguarded and mounted on the cyclic.
NTSB Probable Cause
The inadvertent activation of the helicopter manufacturer's improperly located, unguarded fuel shutoff switch.
