## Discrepancy

DURING ROUTINE MAINTENANCE, PAINT ON THE UPPER TRUNNION BELOW/FORWARD OF THE DRAG LINK ATTACHMENT LUG WAS FOUND TO BE DISTURBED.  AFTER PAINT REMOVAL, THE PRESENCE OF A CRACK WAS CONFIRMED BY DYE PENETRANT.  THE CRACK WAS FOUND TO EXTEND FORWARD TO THE EDGE OF THE MATERIAL ADJACENT TO WHERE THE LOWER STRUT IS INSTALLED. THE NLG ASSY, INCLUDING THE TRUNNION, HAD BEEN INSTALLED ON THE ACFT IN AUGUST 2010 AND  HAD UNDERGONE 6,933 LANDINGS AT THE TIME THE CRACK WAS DISCOVERED.
