## Discrepancy

DURING PREFLIGHT, FLIGHT CREW NOTICED LT INBD TIRE LOOKED LOW.  MX DISCOVERED TIRE ALMOST COMPLETELY DEFLATED BUT NOT BLOWN.  WHEEL ASSYS ONLY HAD 9 CYCLES SINCE IT WAS O/H. R & R WHEEL/TIRE ASSY. INSPECTED REMOVED WHEEL ASSY AND FOUND AIR LEAKING FROM RIM NEAR VALVE STEM LOCATION (BUT NOT FROM VALVE STEM).  MX BELIEVES THAT LEAK IS COMING FROM THE WHEEL HALF SEALING O-RING.  THEY ALSO NOTICED THE WHEEL HALF SEALING O-RING WAS A DIFFERNT COLOR (BLUE) THAN NORMAL (BLACK).
