## Discrepancy

DURING ANNUAL INSPECTION FOR IMPORTATION TO US, THE RT AILERON WAS OBSERVED TO BE MISALIGNED WITH THE WING.  INSPECTION REVEALED BOTH UPPER OTBD AILERON MOUNTING SCREWS WERE NOT ENGAGING HINGE NUTPLATES.  THIS ALLOWED THE AILERON TO MOVE AFT AND DOWN WITH POTENTIAL FOR INFLIGHT SEPARATION.  AILERON WAS REMOVED, INSPECTED AND REINSTALLED IAW THE MM USING NEW HARDWARE.  ACFT HAS 1 HR FLIGHT TIME SINCE ANNUAL INSPECTION WAS COMPLETED.
