## Discrepancy

EXCESSIVE AILERON FORCE REQUIRED ONCE AIRBORNE ALONG THE LONGITUDINAL AXIS.  AIRCRAFT ROLLED LEFT ON TAKEOFF AND REQUIRED 3 3/4 UNITS OF AILERON TRIM WITH A CENTERED INCLINOMETER (BALL).  ALMOST FELT AS IF THE AUTOPILOT WAS ENGAGED.REMOVE AND REPLACE AUTOPILOT SERVO FOR AILERONS.  OPS CHECKS GOOD.  AILERON CONTROL FELT NORMAL THROUGH FULL TRAVEL.
