NTSB narrative

While approaching the initial approach fix (IAF), in instrument conditions and heavy rain, the airplane's engine experienced a partial loss of power. Unable to maintain altitude, the pilot declared an emergency and established a descent at best glide speed. Once below the 1,000-foot ceiling, the pilot secured the engine and performed an emergency landing on rolling terrain among mesquite trees and cacti. The airplane came to rest on its left side with the firewall and engine separated from the fuselage. The pilot was able to exit the airplane unassisted. Following the accident, the airplane was recovered to a secure hangar and examined. No preimpact anomalies were identified during the examination that contributed to the partial loss of engine power.
