On May 28, 1999, about 1340 hours mountain standard time, a Cessna 180, N9270C, owned and operated by the pilot, experienced a total loss of engine power approaching the Sedona Airport, Sedona, Arizona. The pilot made a hard landing in the dirt short of runway 21, and the airplane was substantially damaged. Neither the private pilot nor the two passengers were injured during the personal flight which was conducted under 14 CFR Part 91. Visual meteorological conditions prevailed, and no flight plan was filed. The nonstop flight originated from Wichita, Kansas, at a pilot reported time of 1000 central daylight time. The pilot verbally reported to the Safety Board investigator that he had previously flown from the Wichita Mid-Continent Airport to Sedona without refueling, and he was familiar with the route. He reported having about 1,800 hours experience flying his airplane. No adverse weather conditions were experienced during the en route portion of the flight. The pilot stated that his airplane had been modified, and it carried a total of 73 gallons of fuel. The fuel consumption rate was normally about 10.5 gallons per hour. The pilot reported that approaching the Sedona airport, the engine stopped because he had exhausted all fuel in the right and auxiliary fuel tanks. He reacted to the situation by repositioning the fuel selector to the left fuel tank, but engine power was not restored. At the time of the engine power loss, the pilot was descending through 8,500 feet mean sea level, and was over the airport. The airport's elevation is 4,827 feet msl, and the runway is 5,132 feet long. The pilot entered the traffic pattern and flew the downwind, base, and final approach legs. According to the pilot, he encountered a downdraft while on the base leg. On final approach the airspeed decreased, and he contacted the ground between 10 and 15 feet short of the runway in a stalled attitude. After the accident the pilot attempted to start the engine. He stated that the left fuel tank contained several gallons of fuel, and after several seconds of cranking the engine started and operated normally. He also reported that during the flight all of the airplane's systems had functioned normally. In the pilot's completed report, he indicated that his departure from Wichita was at 1000 central time, and the accident occurred at 1415 mountain standard time. A Red Rock Aviation line service technician, who was based at the Sedona airport, reported to the Safety Board investigator that he observed the accident, and it occurred about 1340 mountain standard time. Also, the wind was from 240 degrees at 8 knots, with gusts to 14 knots. The temperature was 83 degrees Farenheit. Under the direction of the Safety Board, an airframe and powerplant mechanic from Canyon Mesa Aviation examined the airplane. The mechanic reported that both of the airplane's wing fuel tank gauges and the auxiliary tank gauge registered empty.
