## Discrepancy

ON TAKEOFF WE NOTICED A FLUCTUATION OF TRQ 1% AND 2% ABOVE AND BELOW TRQ RATING.  NH AND PROP RPM FLUCTUATION ALSO TOOK PLACE.  AFTER SETTING CLIMB POWER, EVERYTHING SEEMED TO STABILIZE.  REMOVED FROM SERVICE.  NR 2 ENG FMU & FADEC WERE R & R AS PRECAUTIONARY PER ENGINEERING.  ALL ASSOCIATED OPS TESTS WERE NORMAL FOR ALL COMPONENTS CHANGED & NO FLUCTUATIONS WERE NOTED.  RETURNED TO SERVICE.
