## Discrepancy

DURING AIRCRAFT START UP, IT WAS NOTICED THAT THE NR 1 ENGINE HAD FIRE EXITING THE EXHAUST. THROUGH TROUBLESHOOTING PROCEDURES, WE NOTICED WE COULD NOT GO MORE THAN 30% N1 BEFORE THE FIRE STARTED. AFTER MORE TROUBLESHOOTING IT WAS DETERMINED THAT BOTH START (FUEL) INJECTORS ON THE NR 1 ENGINE WERE AT FAULT. AFTER REPLACEMENT OF BOTH START INJECTORS THE NR 1 ENGINE WORKED AND STARTED AS SHOULD.
