## Discrepancy

PILOT NOTICED AFTER DESCENT TO FLIGHT LEVEL 1500 FEET, LEVELING OFF AND ADDING POWER, TORQUE INDICATION DROPPED 200 AND RECOVERED ON ITS OWN WITH NO INPUT TO THE POWER LEVER.  AFTER DISCUSSION WITH PRATT AND WHITTNEY, IT WAS DETERMINED THAT THE FUEL CONTROL DESCENT BELLOWS WAS THE ISSUE.
