## Discrepancy

FOUND RT MAIN TIRE WAS LOCKED UP. PUT WHEEL ON DOLLY AND PULLED PLANE TO HANGER. CLOSER LOOK IN HANGER FOUND THAT  RIM HAD BLOWN APART. DEFLATED TIRE AND LOOKED INSIDE RIM. FOUND PIECE BROKEN OUT OF CENTER SECTION OF RIM. CRACKS WERE FOUND AROUND BOLT HOLES OF RIM HALVES. EXAMINED BROKEN PIECE AND FOUND THAT PORTION OF CRACK WAS OLD, REST BEING NEW.  WITH AIR PRESSURE IN THE TIRE, IT WAS TRYING TO BLOW IT APART. HAVE SEEN THIS PROBLEM ALOT WITH MFG WHEELS HAVING CRACKS AROUND BOLT HOLES. BUT NEVER SEEN ONE COME APART. YOU CAN ONLY SEE CRACKS WHEN CHANGING TIRE FROM INSIDE. THINK IT IS FROM OVER TIGHTENING THE BOLTS UPON ASSEMBLY WHEN CHANGING TIRES. ALSO, HAVING STEEL BOLTS THREADING INTO ALUMINUM HOUSING.
