## Discrepancy

PILOT REPORTED THAT DURING CRUISE FLIGHT,  THE ENG OUT LIGHT ILLUMINATE. AFTER A CHECK OF THE GAGES THERE WHERE NO OTHER INDICATIONS OF A ENGINE FAILURE. SHORTLY AFTER ANOTHER CHECK OF THE GAGES THE N1 GAGE READ 0. I SUSPECTED A GAGE MALFUNCTION AND INITIATED A DECENT TOWARDS THE DRAGON LZ TO MAKE A PRECAUTIONARY LANDING. AFTER LANDING I RADIOED 978 THAT I HAD LANDED SAFELY AND THEY INITIATED A
RECOVERY SHIP.  MAINTENANCE ARRIVED AND INSPECTED THE AIRCRAFT AND DETERMINED THAT THE N1 TACH GENERATOR WAS INOPERATIVE AND WAS REPLACED.  AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE POST GROUND RUNS.
