## Discrepancy

PISTON PIN BROKE IN-FLIGHT CAUSING MASSIVE DAMAGE INTERNALLY IN ENGINE.  THE CRACKSHAFT AND ONE CYLINDER WERE THE ONLY ITEMS SALVAGEABLE.  PILOT NOTICED ENGINE ROUGNESS AND LOSS OF OIL PRESSURE.  AIRPLANE LANDED WITHOUT DAMAGE TO AIRCRAFT OR PILOT.  ENGINE QUIT COMPLETELY AFTER TOUCH-DOWN.
