## Discrepancy

ON 28 DEC 2002, AEROSTAR N6902T LANDED AT OAJ WITH NR 2 (RT) ENGINE SHUTDOWN AND PROPELLERS FEATHERED.  THE PILOT STATED THAT DURING FLIGHT, HE NOTICED A DROP IN OIL PRESSURE AND SHUTDOWN THE ENGINE.  PRIOR TO SHUTDOWN, THE PILOT STATED THAT ALL OTHER INDICATIONS WERE NORMAL.  UPON EXAMINATION OF THE ENGINE, A CRACK WAS FOUND BELOW THE NR 5 CYLINDER EXTENDING FORWARD TO BELOW THE NR 3 CYLINDER MIDWAY.  THE LOWER PORTION OF THE CASE WERE THE NR 5 CYLINDER ATTACHED HAD SEPARTATED TO THE POINT WHERE THE LOWER MOUNTING HOLES WERE VISIBLE WITH THE CYLINDER STILL ATTACHED TO THE CASE.  INTERNAL DAMAGE IS EXPECTED TO BE FOUND, BUT TO DATE HAS YET TO BE DETERMINED.
