## Discrepancy

INCREASED COLLECTIVE FORCES WERE REQUIRED TO CONTROL AIRCRAFT.  AN INSPECTION OF THE ENTIRE FLIGHT CONTROL SYSTEM WAS PERFORMED WITH NO ANOMALIES.  IT WASN`T UNTIL THE ENTIRE FLIGHT CONTROL SYSTEM WAS PERFORMED WITH NO ANOMALIES.  IT WASN`T UNTIL THE COLLECTIVE SERVO ACTUATOR WAS REPLACED THAT THE DISCREPANCY CLEARED.  THIS SERVO WAS INSTALLED ON 7/25/12 AS "MODIFIED" AFTER SDB 430-11-46, REV A HAD BEEN COMPLIED WITH.  SERVIO ACTUATOR WAS CONVERTED FROM 222-382-001-107 TO 222-382-001-111FM DURING SAME VISIT TO THE REPAIR STATION.  THIS PART ACCUMULATED 1063.0 HOURS SINCE INSTALLED ON THIS ACFT.
