## Discrepancy

(CAN) PILOT NOTICED RISE IN OIL TEMPERATURE AND SMOKE FROM #2 ENGINE. ENGINE WAS SHUTDOWN AND PRECAUTIONARY LANDING WAS CARRIED OUT. POST FLIGHT INSPECTION FOUND THE #2 ENGINE, #5 CYLINDER PISTON PIN PLUG BROKEN AND THE DEBRIS HAD SEIZED THE RINGS CAUSING THE CRANKCASE TO PRESSURIZE AND DISCHARGE OIL OUT OF THE OIL BREATHER PIPE.
