## Discrepancy

(CAN) DURING A CLIMB, THE ENGINE STARTED VIBRATING, AND RUNNING ROUGH. THE FLIGHT WAS CANCELLED AND THE AIRPLANE RETURNED SAFELY TO THE AIRPORT.  TROUBLESHOOTING FOUND THE PROBLEM TO BE A FUEL INJECTOR IN THE NR 1 CYLINDER. THE NOZZLE OF THE INJECTOR WAS MISSING.   A VISUAL INSPECTION OF THE INTAKE VALVE AND CYLINDER FOUND NO DAMAGE.  A COMPRESSION TEST WAS PERFORMED AND WAS NORMAL.  THE INJECTOR WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
