## Analysis

THE ACFT CRASHED DURING A FORCED LANDING AFTER THE ENGINE QUIT WHILE THE FLT WAS IN CRUISE AT 3000 FT. THE PILOT STATED THAT HE EXPERIENCED WHAT WAS DESCRIBED AS A DROP IN OIL PRESSURE FOLLOWED BY A COMPLETE POWER FAILURE. THE PILOT ATTEMPTED A FORCED LANDING IN A PASTURE AT WHICH TIME THE LANDING GEAR COLLAPSED AFTER TOUCH DOWN. THE ACFT IMPACTED THEGROUND ABOUT 300 FT FROM A FENCE AND SKIDDED ANOTHER 100 FT BEYOND THE FENCE. THIS ACFT WAS ONLY 2 HOURS OUT OF AN ANNUAL INSPECTION. THE ENGINE WAS REMOVED FROM THE WRECKED ACFT FOR FURTHER EXAMINATION AND TEST RUN. THE ENGINE RUN-UP WAS ACCOMPLISHED AFTER THE FUEL WAS PORTED THROUGH THE INLET SIDE OF THE FUEL PUMP. THE FUEL GAUGES READ ZERO FOR LEFT AND 1/4 FOR THE RIGHT TANK. THE EXAMINATION FAILED TO REVEAL ANY MATERIAL OR SYSTEM MALFUNCTION/FAILURE.
