## Discrepancy

(CAN) FLIGHT WITH AN UNDETECTED FAILURE PILOT NOTICED AN EXTERNAL OIL LEAK FROM THE PROPELLER SHAFT AREA DURING PRE-FLIGHT WALK AROUND.  INSPECTION REVEALED A CRACK ALMOST HALF WAY AROUND THE CIRCUMFERENCE OF THE PROPELLER SHAFT AT APPROXIMATELY 4 TO 4.5 INCHES FROM THE FRONT FLANGE.  THE PROPELLER SHAFT IS TO BE SENT TO P&WC SERVICE INVESTIGATION AS SOON AS POSSIBLE.  MANUFACTURER ENGINEERING IS CONDUCTING A PRELIMINARY VISUAL INSPECTION AT THE SHOP.
