Analysis

The pilot of a single engine homebuilt stated he was at a cruise altitude of 3000 feet MSL when his engine quit running. He stated he switched on the fuel boost pump but saw only '0' fuel pressure. He stated he was within 2 miles of his destination airport and began an attempted dead stick landing glide. As the airplane neared the airport he realized he would not clear obstacles in his glidepath. He stated he decided to land in a wheat field. During an interview with police a witness stated he saw the airplane 'coming in nose first' and that 'at the last minute it pulled its nose up and hit belly first.' An on-scene investigation revealed the left fuel tank empty and the fuel tank selector valve on the left tank. The right fuel tank was found full.
