The NTSB's narrative final · quoted from the NTSB record
The amateur-built experimental helicopter landed hard following a loss of engine power while in a 6-foot hover. The pilot said the helicopter was equipped with a 150-horsepower turbo shaft engine. The engine was originally developed for a military application and the manufacturer has since introduced it for sale to amateur builders. The pilot reported that he was in a hover 6 feet above the taxiway after landing when the engine lost power. He attempted a hovering autorotation; however, the helicopter landed hard. He examined the engine and related systems. He said the loss of power was due to a fractured and separated solid fuel line that went from the fuel manifold to one of the injectors. He stated that the crack was near a joint in the line and appeared to be from fatigue.

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 LAX07CA063.
