## Discrepancy

(CAN) CORROSION WAS FOUND ON THE LEFT HAND AILERON UNDER THE STATIC WICKS. THE AILERO N WAS REMOVED AND DISASSEMBLED. AFTER REMOVING THE UPPER SKIN, IT WAS DISCOVEREDTHAT THE UPPER AND LOWER SKINS WERE CRACKED IN MULTIPLE LOCATIONS, JUST AFT OFTHE JOINT WHERE THE NOSE SKIN OVER LAPS THE AFT SKIN. RAYTHEON HAS PUBLISHED A S.B. (SB57-3148) TO INSPECT THE RIGHT HAND AILERON FOR CRACKS IN THE SAME LOCATION,BUT NOT FOR THE LEFT AILERON.
