## Discrepancy

CLIMBING THROUGH 27,500 FT, THE PITCH TRIM ANNUNCIATOR ILLUMINATED ON BOTH PFDS.  THE AUTOMATION WAS DISENGAGED.  WE LEVELED AT FL 280.  WE ATTEMPTED TO MOVE THE THE TRIM VIA THE YOKE SWITCH AND IT DID NOT RESPOND.  WE WERE ABLE TO MANIPULATE THE MANUAL TRIM WHEEL.  WE MANUALLY PULLED THE PITCH TRIM CIRCUIT BREAKER AND RESET IT.  WE ALSO OBSERVED THAT THE FLAP INDICATOR WAS NOT AT 0.  THE FLAP HANDLE WAS CYCLED & THE INDICATOR MOVED TO 0.  WE DID NOT OBSERVE A HYDRAULULIC PRESS LIGHT OR STAB MISCOMPARE ON THE ANNUNCIATOR.  PLEASE NOTE: WE DE-ICED IN ASE & TEMPERATURES WERE BELOW FREEZING.  AS THE FLIGHT CONTINUED INTO WARMER AIR THE TRIM BEHAVED NORMALLY AND WE LANDED WITHOUT INCIDENT.  "CORRECTIVE ACTION" CHECKED ELECTRIC ELEVATOR TRIM ACTUATOR TORQUE AND NOTED THAT IT WAS LOW.  REMOVED ELECTRIC ELEVATOR TRIM ACTUATOR AND MOUNTING PAD, ADJUSTED.
TORQUE AND REINSTALLED ACTUATOR AND MOUNTING PAD. IAW THE CESSNA 560XL
