## Discrepancy

DURING A PRELIMINARY INSPECTION PRIOR TO A SCHEDULED INSPECTION, THE AIRCRAFT WAS FOUND TO HAVE HAIL DAMAGE TO THE LEFT AND RIGHT WINGS, AILERONS, FLAPS, HORIZONTAL STABILIZERS, AND ELEVATORS.  AILERONS AND ELEVATORS WERE DENTED BEYOND SRM LIMITS IAW SRM 12-B-57-60-00-00A-661A-A AND 12-B-55-00-00-00A-661B-A.  AILERONS WERE REPLACED WITH NEW UNITS IAW TM-12-006009 AND AMM 12-B-57-60-02-00A-920A-A.  ELEVATORS WERE REPLACED WITH REPAIRED UNITS IAW AMM 12-B-55-20-01-00A-920A-A.  PILATUS ENGINEERING IS CURRENTLY ASSESSING THE DAMAGE TO THE WINGS, HORIZONTAL STABILIZERS, AND FLAP STRUCTURES TO DETERMINE APPLICABLE REPAIRS IAW SRM 12-B-51-10-04-00A-661A-A.
