## Discrepancy

(CAN) PILOTS REPORT CHT HIGH, THEN CHT TEMP FELL OFF TO BOTTOM OF GREEN ARC.  ENGINE LOST SOME MANIFOLD PRESSURE.  ON INSPECTION AFTER LANDING, IT DISCOVERED THAT CYLINDER NR 6, CYLINDER HEAD HAD COMPLETELY SEPARATED FROM THE BARREL.  NO OTHER DAMAGE.  CYLINDER WAS REPLACED WITH A SERVICEABLE CYLINDER ASSY AND AIRCRAFT RETURNED TO SERVICE.
