## Discrepancy

(CAN) ON INITIAL POWER UP FOR T/O THE NR 2 ENGINE ONLY WENT TO 51 PERCENT TQ DESPITE BEING SET FOR AN 83 T/O POWER. THE CREW REJECTED TAKEOFF.  THEY THEN DE-SELECTED REDUCED POWER TAKEOFF AND COMPLETED A STATIC RUN DURING WHICH THE ENGINE POWER WENT TO 85 PERCENT.  THEY ATTEMPTED A SECOND T/O AND ONLY GOT 49 PERCENT TQ.  ALL OTHER ENGINE PARAMETERS WERE NORMAL. THE EVENT MARKER WAS ACTIVATED AND INDICATED NR 2 ENGINE TQ HANGING AT 44 PERCENT WITH FUEL FLOW LOWER THAN NR 1 ENGINE BY 200PPH.  THE PROBLEM WAS TRACED BACK TO A FAULTY FLOW DIVIDER WHICH WAS REPLACED BEFORE THE ACFT WAS RETUNED TO SERVICE.  THE FAULTY DIVIDER WILL BE SENT TO FOR INVESTIGATION.
