## Discrepancy

DURING A SCHEDULED PHASE INSPECTION THE LEFT AILERON WAS REMOVED.  UPON REMOVAL THE LEADING EDGE SKIN AT THE WEIGHT ATTACHMENT SCREWS WAS FOUND CRACKED.  THIS HAD ALLOWED THE SKIN TO CRACK ABOVE AND BELOW A SCREW APPROX. .5000.  THE RIGHT AILERON WAS ALSO REMOVED AND TWO OF THESE LEADING EDGE WEIGHT SCREWS WERE ALSO FOUND LOOSE.
