## Discrepancy

(CAN) DURING A ROUTINE INSPECTION THE LT MLG LEG WAS EXPOSED AND IT WAS NOTICED THAT THE LEG WAS CRACKED AT THE "Y" INTERSECTION OF THE TUBES.  CRACK WAS CONFIRMED USING FLUORESCENT PENETRANT NDT.  NO HARD LANDINGS WERE REPORTED DURING THE SERVICE OF THIS GEAR LEG.  THE CRACK IS NOT IN THE PARENT METAL OF THE TUBE BUT RATHER IN THE SURFACE OF THE WELD.
