## Discrepancy

DURING ANNUAL INSPECTION THE STABILATOR WAS REMOVED FOR FURTHER INSPECTION.  THIS IS DUE TO PREVIOUS PROBLEMS ON OTHER PA24 AND PA30/39 AIRCRAFT WITH STABILATOR TORQUE TUBE AND ATTACHMENT BOLTS WITH EXCESSIVE CORROSION.  BOTH BOLTS AN175C33A THAT ATTACHES THE STABILATOR HORN ASSY TO THE TORQUE TUBE WERE SEVERELY CORRODED.  ALSO CORRODED WERE THE FOLLOWING BOLTS:  AN24-46A (400-932), AN174-22A (402-321)..  THE BOLTS ATTACHING THE STABILATOR TO THE TORQUE TUBE WERE ALSO CORRODED SEVERELY.  THE BOLTS HAD TO BE REMOVED BY AN IMPACT TOOL.  THESE WERE TO BE REPLACED OR INSPECTED IAW AD 74-13-03.  TT 3681.
