ON SATURDAY AUGUST 25TH AT ABOUT 11:00 MDT A CESSNA 140 WAS INVOLVED IN AN ACCIDENT NEAR KSPF AIRPORT. AFTER A CROSS COUNTRY SOLO, THE PILOT WENT THROUGH THE LANDING CHECKLIST. THE PILOT TURNED DOWNWIND AT KSPF AND APPLIED CARB HEAT RESULTING IN THE ENGINE IMMEDIATELY DROPPING BELOW 1000 RPM. THE PILOT BEGAN EMERGENCY PROCEDURES, INCLUDING ADJUSTING THE CARB HEAT. THE PILOT MADE A FORCED LANDING IN A FIELD HITTING A BARBED WIRE FENCE, THE WHEELS CONTACTING THE UPPER WIRE CAUSING THE AIRPLANE TO PITCH DOWNWARD RAPIDLY. THE LANDING GEAR CONTACTED A SMALL RISE IN THE TERRAIN CAUSING THE AIRPLANE TO NOSE OVER WITH THE FRONT OF THE AIRPLANE CONTACTING THE GROUND.
