## Discrepancy

PUSHROD WAS CORRODED FROM INSIDE OUT, ABOUT MID-WAY DOWN LENGTH OF PUSHROD.  CAUSED BY LACK OF CORROSION PROTECTION ON INSIDE OF PUSHROD.  FOUND WHEN PUSHROD WAS REMOVED FROM C/W NEW NDT INSPECTION REQUIREMENT.  ON VISUAL INSPECTION, FOUND .1250 INCH DIAMETER HOLE ON PUSHROD.  HOLE WAS NOT VISIBLE FROM INSPECTING PANEL OR AILERON GAP.  SUBMITTER RECOMMENDS AFTER C/W NDT INSPECTION, PUSHROD SHOULD BE FILLED WITH LPS-3 OR OTHER CORROSION INHIBITOR, AND DETAILED INSPECTION DURING WING INSPECTION.
