## Discrepancy

(CAN) FLIGHT CREW REPORTED OCCASIONAL PROBLEMS WITH TORQUE INDICATION DURING POWER REDUCTIONS. TORQUE INDICATION WOULD HANG UP AT VARIOUS HIGH SETTINGS DESPITE POWER REDUCTIONS TO IDLE. FROM A PREVIOUS CASE OF THIS ON ANOTHER AIRCRAFT, THE POWER REDUCTION CASE WAS SPLIT WITH AN EXPECTATION THAT THE TORQUEMETER VALVE WAS PREMATURELY WORN, AND IT WAS.   A PREVIOUS SUBMISSION UNDER AGL-0120 REFLECTS EXACTLY THE SAME PROBLEM, PRESENTATION AND FIX.
