## Discrepancy

PUSH/PULL TUBE WAS REMOVED FROM THE ACFT DURING AN ANNUAL INSPECTION AND WAS FOUND TO HAVE SEVERE PITTING AND HOLES THRU THE TUBE.   FOUND THE ALUMINUM WAS SEVERLY CORRODED AT THE AREA WHERE IT MATES WITH THE STEEL TUBE. CORROSION WAS SO SEVERE IT CRACKED THE FITTING.  ONLY WAY TO DISCOVER THE CRACK WAS TO DISASSEMBLE PART WHICH IS USUALLY ONLY DONE AT A REPAIR SHOP.
