## Discrepancy

DURING LEAK DOWN CHECK AFTER REBUILD OF WHEEL, DISCOVERED AIR LEAKING FROM VALVE STEM AREA.  REMOVED VALVE STEM FROM WHEEL AND HAD STEM NTD'D BY LOCAL SHOP.  THEY DISCOVERED A CRACK IN THE SEAL AREA OF THE STEM.  REPLACED VALVE STEM WITH A NEW UNIT.  THE DUNLOP OVERHAUL MANUAL DOES NOT SPECIFY NDT OF THE VALVE STEM DURING OVERHAUL PROCEDURES.
