## Discrepancy

(CAN) OIL LEAK DURING FLIGHT, THE CREW REPORTED HIGH VIBRATIONS WHICH WAS FOLLOWED DURING APPROACH BY OIL PRESSURE FLUCTUATIONS. DURING TAXI AFTER LANDING, THE LOW OIL PRESSURE WARNING LIGHT FLICKERED ON AND OFF. POST FLIGHT INSPECTION FOUND A SEVERE OIL LEAK AT THE PROPELLER SHAFT. FURTHER INSPECTION FOUND A CIRCUMFERENTIAL CRACK ON THE PROPELLER SHAFT FROM WHICH OIL WAS ESCAPING. THE ENGINE WILL BE FORWARDED TO STANDARD AERO AND THE SHAFT WILL BE SENT TO P&WC FOR INVESTIGATION. (TC# 20101229003)
