## Discrepancy

DURING TAKEOFF THROUGH 3000 FEET WITH THROTTLE IN TAKE OFF, THE RT ENGINE N2 WENT TO 102 & INDICATED RED.  THE FLYING PILOT FELT A POWER BUMP & THEN SLOWLY RETARDED THE RT ENG TO IDLE.  THE ITT ON THE RT ENG SLOWLY SURGED BETWEEN AROUND 500 & 700 DEGREES A COUPLE TIMES.  SHORTLY AFTER THE THROTTLE WAS AT IDLE WE RECEIVED THE AMBER CAS MESSAGE FAN DAMAGE RT.   ACCOMPLISHED INSPECTION IAW MM 75-33-10 AND ACCOMPLISHED BORESCOPE OF THE COMPRESSOR SECTION IAW MM 72-30-00. NO DEFECTS AT TIME OF INSPECTION.  REMOVED AND INSTALLED FPMU IAW MM 73-21-10. LEAK AND OP CHECKED GOOD.
