## Discrepancy

THE WHEEL NOT TURNING LIGHT ILLUMINATED UPON LANDING, NR 2 MAIN TIRE BLEW.  MAINTENANCE FOUND THE NR 2 BRAKE LOCKED UP AND THE QUICK DISCONNECT ON NR 2 BRAKE WAS LOOSE AND LEAKING.  THE NR 2 BRAKE, NR 2 WHEEL ASSY, AND QUICK DISCONNECT WERE REPLACED.  IN ADDITION, THE NR 1 WHEEL ASSEMBLY WAS REPLACED AS A PRECAUTIONARY MEASURE, LEAK AND OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT AND ENGINE INLET WERE INSPECTED AND NO DAMAGE WAS FOUND.  *S/D*  EXAMINATION OF THE BRAKE DURING TEARDOWN REVEALED NORMAL WEAR.  ENGINEERING CONCLUDED THAT BRAKE LOCK UP WAS DUE TO FAILURE AND SUBSEQUENT LEAKAGE OF THE NR 2 BRAKE QUICK DISCONNECT.
