NTSB summary
On October 4, 1998, approximately 1515 hours Pacific daylight time, a Burson Revolution Mini 500, N418MB, crashed in hilly terrain near Moorpark, California. The amateur built experimental helicopter was destroyed and the private pilot/owner suffered fatal injuries. The flight was conducted under the provisions of 14 CFR Part 91 and originated from a nearby rural area about 1430. Visual meteorological conditions prevailed for the personal flight and no flight plan was filed. The pilot's daughter reported that she accompanied the pilot to the takeoff/landing site and helped reinstall the main rotor blades, which had been removed to trailer the helicopter. She stated that her father reported that he planned to fly over the park where she would be, and would then fly over the family residence. She left the site at 1417 and asked him to wait about 45 minutes before flying over the park. The daughter further recalled that the pilot reported that he planned to fly for about 1 1/2 to 2 hours. She never saw or heard him fly over the park, and he was not seen over the family house. The pilot's wife reported the pilot as missing and an Alert Notification (ALNOT) was issued at 2040.
