## Discrepancy

DURING CLIMB THE NUMBER 2 ENGINE BEGAN MAKING A POPPING NOISE AND THE MANIFOLD AND BMEP READINGS WERE WIDLY FLUCTUATING. THE CREW NOTICED A SLIGHT DROP IN THE ENGINE OIL LEVEL ON THE NUMBER TWO ENGINE. THE CREW ELECTED TO PREFORM A PRECAUTIONARY ENGINE SHUT DOWN ON THE NUMBER TWO ENGINE. UPON INSPECTION OF THE ENGINE, THE MAINTENANCE CREW DICOVERED THE NUMBER ONE CYLINDER WAS CRACKED. THIS CAUSED A SLIGHT LOSS OF POWER AND SLIGHT LOSS OF ENGINE OIL.
