## Discrepancy

(CAN) WHEN PERFORMING A CYLINDER DIFFERENTIAL COMPRESSION CHECK, FOUND CYLINDER NR 5 HAD A 60/80 COMPRESSION, AND AIR WAS LEAKING OUTSIDE CYLINDER.  AFTER FURTHER INSPECTION, FOUND CRACK COULD BE SEEN JUST INBOARD OF THE EXHAUST PIPE FLANGE. CYLINDER WAS REMOVED FROM SERVICE. NEW OVERHAULED CYLINDER WAS INSTALLED.
