## Discrepancy

BETWEEN FLIGHTS,  THE ACFT NOSE TIRE WAS FLAT.  THE WHEEL ASSEMBLY WAS REPLACED WITH A BUILT UP WHEEL ASSY.  THE FLAT WHEEL ASSY WAS DISASSEMBLED AND TUBE INSPECTED; THIS REVEALED A SMALL HOLE IN THE TUBE, ABOUT .01" LONG.  CLOSER INSPECTION SHOWS A VERY TINY BUBBLE IN THE TUBE MATERIAL, LIKE A BUBBLE IN SODA.  THIS TUBE WAS INSTALLED ON THE ACFT AS PART OF A BUILT-UP WHEEL ASSY ON 9/26/2013 AND HAD ACCRUED 194.2 HOURS TIS.  THE TIRE WAS SERVICED ONLY WITH DRY NITROGEN.
