Read the full NTSB narrative

WHILE DESCENDING TO 6000 FEET THE PILOT EXPERIENCED A COMPLETE LOSS OF ENGINE OIL SUPPLY. THE WINDSCREEN WAS COVERED WITH OIL AND THE PILOT HAD TO USE THE SIDE WINDOW TO GAIN FORWARD VISIBILITY. AFTER COMPLETING THE EMERGENCY LANDING CHECK THE ENGINE SEIZED. AN EMERGENCY LANDING AREA WAS SELECTED. THE AIRPLANE COLLIDED WITH A TREE ABOUT 10 FEET ABOVE THE GROUND. THE AIRPLANE CONTINUED ABOUT 200 FEET BEFORE COMING TO A STOP IN AN UPRIGHT POSITION. THE POST CRASH EXAMINATION INDICATED THAT THE PROPELLER ASSEMBLY HAD SEPARATED FROM THE ENGINE PROPELLER SHAFT. THE FRACTURE ANALYSIS OF THE BOLTS DISCLOSED THAT FOUR BOLTS FAILED IN FATIGUE. THE PROPELLER WAS OVERHAULED ABOUT 12 HOURS BEFORE THE MISHAP. THE OVERHAUL FACILITY REUSED THE OLD BOLTS AFTER MAGNA-FLUX AND PLATING. THE INSTALLATION TORQUE WAS NOT DETERMINED.
