ON INITIAL CLIMB FOLLOWING TAKEOFF, AT A GROSS WEIGHT APPROXIMATELY 50 POUNDS OVER MAXIMUM, THE AIRPLANE WOULD NEITHER CLIMB NOR ACCELERATE. AFTER TURNING CROSSWIND AT 250 FEET AGL AND 1/2 MILE BEYOND THE RUNWAY END, ENGINE RPM BEGAN TO 'CREEP DOWN.' THE PILOT WAS UNABLE TO RESTORE RPM, THEREFORE, A FORCED LANDING WAS PERFORMED IN A PASTURE. THE AIRPLANE COLLIDED WITH A DITCH AND FENCE, NOSED OVER, AND CAUGHT FIRE. AN ENGINE EXAMINATION REVEALED THAT THE SPARK PLUGS WERE FOULED, MAGNETO IMPULSE COUPLING WEAK, AND RUST AND EVIDENCE OF DETONATION WAS PRESENT IN THE CYLINDERS AND ON PISTON DOMES, WHICH DEGRADED POWER AVAILABLE.
