## Discrepancy

(AUS) BRAKE ROTATING DISC FAILED. A PART OF THE FAILED DISC PUNCTURED THE WHEEL INNER HALF AND DEFLATED THE TUBE. INVESTIGATION FOUND NO DISCOLOURATION BUT FOUND THAT THE SLOTS HAD SPREAD FLATTENING THE OUTER CIRCUMFERENCE BETWEEN THE DRIVE RECESSES. THE THREE ROTATING DISCS ON THE BRAKE UNIT HAD CRACKS EMINATING FROM THEEXPANSION SLOTS.
