## Discrepancy

(CAN) UPON DESCENT FORM 25,000 FT THROUGH MODERATE TURBULENCE, THE LT ENGINE POWER WOULD NOT RETARD. THE POWER LEVER WAS MOVED FROM FULL POWER TO FLIGHT IDLE AND NO REPSONSE.  UPON REACHING 20,000 FT THE ENGINE BECAME RESPONSIVE AGAIN TO POWER LEVER MOVEMENT.  THE AIRCRAFT WAS RUN ON THE GROUND BY MAINTENANCE PERSONNEL AND NO FAULTS COULD BE FOUND.  IN DISCUSSION WITH THE MANUFACTURER, MAINTENANCE ELECTED TO REPLACE THE THE P2T2 SENSOR.  GROUND RUNS CARRIED OUT ALL WITHIN MANUFACTURERS PARAMETERS AND AIRCRAFT RETURNED TO SERVICE.  SNAG AHS NOT DUPLICATED ITSELF AGAIN.
