## Discrepancy

DURING PREFLIGHT TRIM WHEEL STIFF AND HARD TO MOVE, FELT SLIGHT BINDING WHEN MOVING THROUGH ZERO MARK.  ALSO, WHEEL SNAPS BACK 1/2 UNIT AFTER RELEASE (IN MANUAL OR ELECTRIC) WHEN SET.  REPLACED ELECTRIC TRIM CONTROL SERVO.  TRIM WHEEL HAS FULL MOVEMENT WITHOUT BINDING OR BACK PRESSURE.  OPS CHECK GOOD.
