## Discrepancy

ORF - FLT178 - DURING CRUISE, EN ROUTE FROM CLT TO BOS, THE NR 1 ENGINE CSD HIGH OIL TEMPERATURE LIGHT ILLUMINATED.  THE APU WAS ALREADY ON MEL, SO THE CREW DISCONNECTED THE NR 1 ENGINE CSD AND DIVERTED TO ORF WHERE THE FLIGHT LANDED WITHOUT FURTHER INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE REMOVED AND REPLACED THE NR 1 ENGINE CSD PER MM 24-11-11-4 ALONG WITH THE OIL COOLER PER MM 24-11-21.  OPERATIONAL CHECK AND LEAK CHECK GOOD.  CLEARED APU MEL 49-1 WITH THE REPLACEMENT OF THE APU M280 MODULE.  OPERATIONAL CHECK GOOD.
