NR 2 ENGINE REPORT POWER FLUCTUATES SYMPTOMS OR PATTERN ALONG WITH FAULT CODES. FRM CODE 73 21 XD RT ENG EPR+EGT FLUCTUATES AFTER POWER CHANGE IN CLRWX COND DURING CLIMB EPR+--. THIS IS CAUSED BY THE FUEL CONTROL (FCU) DECELERATION (DECEL) SCHEDULE BEING TO CLOSE TO THE ENGINE'S STEADY STATE OPERATING LINE. THE FCU WILL CYCLE THE 3.0 AND 3.5 BLEEDS TRYING TO KEEP UP WITH THE FCU DECEL SCHEDULE AND THE ENGINE OPERATING LINE, WHICH CAUSES POWER FLUCTUATIONS. THIS IS ESPECIALLY THE CASE ON ENGINES NEW OUT OF THE SHOP. THIS POWER FLUCTUATION IS CORRECTED BY ADJUSTING THE FCU DECEL SCHEDULE AWAY FROM THE STEADY STATE OPERATING LINE.
