## Discrepancy

AFTER TURNING ON THE NR 4 CTC, THE AIRCRAFT FILLED WITH A BURNING OIL SMELL.  TURNED NR 4 CTC OFF AND SMELL DISSIPATED.  NOTE: DID NOT GET AN OVERHEAT LIGHT, RPM'S NORMAL.  FOUND NR 4 CTC FAN BLADE DAMAGED.  REMOVED AND REPLACED NR 4 CTC.  OPS CHECKED GOOD IAW DC-8 MM CHAPTER 21.  ADDITIONAL INFO:  THE CREW HAD THE PROBLEM WITH THE NR 4 CTC ON TAKEOFF OUT OF ILN EN ROUTE TO SAT, FLIGHT 392.  DID NOT DO AN AIR TURNBACK, NOR ABORT TAKEOFF.  MAINTENANCE ALSO FOUND THE NR 3 CTCS DAMAGED.  BOTH THE NR 3 AND NR 4 CTCS WERE CHANGED OUT.  A BIRD STRIKE INSPECTION WAS ALSO PERFORMED WITH NO ADDITIONAL FINDINGS.
