## Discrepancy

LEFT ENGINE SURGED ABOUT 5 PERCENT N1 SHORTLY AFTER TAKEOFF (TO APPROX 100%) WHILE THE THRUST LEVER WAS IN MCT THEN RETURNED TO NORMAL.  POWER WAS BROUGHT BACK TO MCR AND THE LT ENGINE N1 BUG STARTED TO FLUCTUATE FROM 95% TO 92%.  LT ENGINE N1 NEEDLE AND RT ENGINE N1 NEEDLE BUGS WERE STEADY AT 95%.  LT BUG EVENTUALLY STOPPED FLUCTUATING AFTER A COUPLE MINUTES, FLIGHT CONTINUED NORMALLY.
