## Discrepancy

(CAN) AS PROPELLER WAS ROTATED, AIR WAS HEARD ESCAPING FROM NR 2 CYLINDER. A CYLINDER LEAKAGE CHECK WAS CARRIED OUT TO CONFIRM LEAKAGE, AND A SOAP/WATER SOLUTION USED TO LOCATE THE CRACK.  CRACK WAS LOCATED IN CYLINDER HEAD ABOVE EXHAUST VALVE AREA.  CYLINDER ASSY WAS REMOVED FROM SERVICE. THIS IS THE 6TH CYLINDER ASSY FOUND IN THIS CONDITION IN THE PAST TWO MONTHS. ALL CYLINDERS WHERE SAME MFG CYLINDER'S WITH APPROXIMATELY THE SAME 3 OF HOURS.
