## Discrepancy

DURING CRUISE, THE ENGINE SPUTTERED FOR 1-2 SECONDS. THE AIRCRAFT WAS RETURNED TO HOME BASE. A THOROUGH INSPECTION OF THE ENGINE AND SYSTEMS WAS MADE, AND THE ONLY OBSERVABLE ITEM WAS A FUEL INJECTOR NOZZLE THAT PRODUCED A MINOR IRREGULAR FLOW PATTERN DURING TESTING. THE NOZZLES WERE CLEANED THE AIRCRAFT WAS FLOWN WITH NO OPERATIONAL DEFECTS NOTED.
