## Discrepancy

(CAN) DURING ROUTINE INSPECTION A FUEL LEAK WAS NOTED ON THE NR 2 CYLINDER AROUND THE INTAKE PORT.  UPON FURTHER INVESTIGATION, A CRACK WAS NOTED IN THE CYLINDER WALL JUST ABOVE THE INTAKE PORT.  THE CRACK IS APPROXIMATELY 1" IN LENGTH.  THE CYLINDER WAS REPLACED AND THE ACFT RETURNED TO SERVICE.
