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

The helicopter impacted the terrain while performing an autorotation following a loss of engine power. The helicopter was examined and no anomalies could be found that could be associated with a pre-impact condition. About 10 ounces of fuel was all that could be drained from the fuel system. The fuel system was not compromised. A witness saw the helicopter above the tree line behind his house. He said that the helicopter, "...was in view for about 1 1/2 seconds when [the] motor pitch changed and [the] helicopter headed to its right dropping under [the] tree line. After losing sight of [the] helicopter [,] I heard a thud and no explosion and no longer could [hear] it any longer." The pilot had not been issued a pilot certificate other than a student pilot certificate. No instructor endorsement for solo flight was found in the pilot logbook, or on the student pilot certificate. The track data from a global positioning system receiver that was found at the accident site was downloaded to a computer and plotted on a sectional aeronautical chart. The first recorded position on the accident date was 39 degrees 8.5404 minutes north and 95 degrees 9.5766 minutes west at 1438:30 universal coordinated time (UTC). The last recorded position for the accident date was at 38 degrees 26.0904 minutes north and 94 degrees 6.5526 minutes west at 1608:46 UTC.
