On July 1, 2000, about 1315 hours Pacific daylight time, an experimental Kashan Berkut 540, N600SE, sustained substantial damage when it rolled over and touched down inverted during landing at Hayden Field, Jackpot, Nevada. The private pilot operated the borrowed airplane under the provisions of 14 CFR Part 91. The pilot and one passenger sustained serious injuries. The local personal flight, which was participating in an experimental airplane fly-in, departed Jackpot at an unknown time. Visual meteorological conditions prevailed and no flight plan had been filed. The pilot told a Sheriff's deputy the wind flipped him over when he was on short final. The pilot of the airplane ahead of the accident airplane told the deputy he observed numerous dust devils and gusty winds in the airport vicinity and broadcast an advisory about the conditions. The deputy said thunderstorms were in the area, and the winds were 10 to 15 knots and swirling. A Pilot/Operator Aircraft Accident Report, Form 6120.1/2, was sent via certified mail and not returned.
