The NTSB's narrative final · quoted from the NTSB record

After completing a three-leg cross-country training flight in the helicopter, the solo student was hover-taxiing about 15 ft above the taxiway surface. Witnesses reported that gusting winds prevailed and that they saw the helicopter enter a spin, followed by a nose-low impact with the ground. The helicopter was substantially damaged. The pilot was seriously injured and unable to recall the accident sequence. Postaccident examination of the airframe and engine revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation.

About this page

Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number ERA19LA287.
