## Discrepancy

ELEVATOR AND AILERON SERVO'S STUCK IN FLIGHT. OWNER/PILOT CLEARED WITH FORCE. REMOVED OLD UNIT AND REPLACED WITH MANUFACTURES NEW REPLACEMENT PART. RETURNED AIRCRAFT TO SERVICE AFTER COMPLETE TEST PER MANUFACTURES RECOMMENDATIONS. ELEVATOR SERVO CHANGED PRIOR FOR SAME ISSUE, AS I WAS INFORMED.
