## Discrepancy

DURING DESCENT REDUCED POWER LEVERS TO IDLE, RT ENG WOULD NOT DECREASE BELOW 80 PERCENT N1, 500 PDS TORQUE, NORMAL SETTINGS 63 PERCENT & 100 PDS.  INFORMED TOWER THAT WE HAD AN ENG ABNORMALITY & MAY NEED TO SHUT DOWN ON THE RUNWAY BUT DIDN'T NEED OTHER ASSISTANCE.  PILOT FEATHERED RT PROP, LANDED WITH NO ISSUES & TAXIED BACK TO RAMP.  WE BOARDED THE ACFT & HAD THE PILOT RUN THE ENG UP & WITNESSED THE SAME ISSUE WAS STILL PRESENT BUT N1 HAD DECREASED TO 70 PERCENT N1. THE ACFT WAS SHUT DOWN & WE INSPECTED THE FUEL CONTROL LINKAGE & COULD NOT FIND ANY ISSUES WITH THE LINKAGE OR RIGGING.  WE STARTED & RAN THE ACFT AGAIN ON THE RAMP & THE RT ENG WAS OPERATING NORMALLY WITH NO ISSUES.  CALLED THE FUEL CONTROL OVERHAUL SHOP & CAME TO THE CONCLUSION THAT IT WAS A DECELERATION ISSUE & REPLACED THE FUEL CONTROL WITH AN OVERHAULED FUEL CONTROL.  WE WILL SEND THIS FUEL CONTROL IN FOR EVALUATION TO TRY & DETERMINE THE CAUSE.
