THE OIL PRESSURE DECREASED TO ZERO AND SHORTLY THEREAFTER PROPELLER CONTROL WAS LOST. DUE TO A ROUGH RUNNING ENGINE AN EMERGENCY LANDING WAS ATTEMPTED. DURING THE WHEELS UP LANDING IN AN UNPLOWED GRASSY FIELD, THE AIRCRAFT STRUCK A FENCE. EXAMINATION OF THE AIRCRAFT REVEALED THE COOLER OIL LINE CAME LOOSE FROM THE INLET FITTING.
