What was found
WHEN THE PILOT DEPARTED AND BEGAN THE TAXI, IMMEDIATELY NOTICED A PROBLEM AND SHUTDOWN. DISCOVERED THE RT WHEEL & TIRE ASSEMBLY WAS COMPLETELY FLAT. AFTER THE WHEEL HAD BEEN REMOVED, AN INSPECTION DISCLOSED THAT THE ASSEMBLY O-RING WAS SLICED IN TWO PLACES. THERE IS ONLY ONE PROBABLE REASON WHY THE O-RING COULD HAVE BEEN DAMAGED IN THIS MANNER: THE O-RING WAS NOT FULLY SEATED IN THE WHEEL SEAL GROOVE IN THE TWO DAMAGED AREAS WHEN THE WHEEL WAS ASSEMBLED.
