## Discrepancy

ON CLIMB OUT THE RT ENG SHOWED LOW FUEL FLOW 3.7 WITH A HIGH EPR 1.71.  THE TMC EPR WAS 1.60.  PUSHING THE THROTTLE UP TO MATCH FUEL FLOW WITH RT ENG RESULTED IN FUEL FLOW ONLY CHANGING 300 - 400 LBS AN HR TO APP 4.1, WHILE EPR INCREASED TO 1.8 - 1.9 WITH NO INCREASE IN POWER OUTPUT, NOTICEABLE YAW.  AIRPLANE COULD NOT CLIMB ABOVE FL220.  R & R RT ENG P1 TUBE ASSEMBLY IAW AMM 73-21-04-4.
