What was found
UPON STARTING THE NR 3 ENGINE, THE T5 WAS OBSERVED TO BE RISING WHILE THE NG WAS SLOW TO RISE. THE START WAS ABORTED WHEN THE T5 HIT 900 DEGREES. MX INVESTIGATED AND FOUND THAT THE FUEL PUMP WAS LEAKING AND THE FUEL WAS GOING THROUGH THE GARLOCK SEAL AND INTO THE ACCESSORY GEAR BOX. THIS FUEL IN THE GEARBOX WAS THEN LEAKING INTO THE COMPRESSOR CAUSING THE HIGH TEMPERATURE DURING THE START. THE FUEL PUMP AND THE GARLOCK SEAL WERE REPLACED, THE FUEL PUMP DRAIN LINE CLEARED, THE OIL SYS WAS FLUSHED AND REPLENISHED AND THE ACFT WAS RETURNED TO SERVICE.
