## Discrepancy

(CAN) ON THE WAY BACK TO THE AIRPORT THE ENGINE DEVELOPED ABNORMAL VIBRATIONS AND THE PILOT DECIDED TO CLIMB TO 2,400 FT, THEN THE ENGINE SUDDENLY STOPPED. THE PILOT DECIDED TO FORCE LAND ON THE AUTO ROUTE IN A WESTERLY DIRECTION. AFTER INSPECTION, IT WAS DETERMINED THAT THERE WAS NO LOSS OF OIL AND THAT THE PROP WAS UNABLE TO TURN. THE ENGINE CRANKSHAFT WAS THE CAUSE OF FAILURE. (TC NR 20070530003)
