## Discrepancy

CLE FLT 2354 THE CREW REPORTED A BANGING NOISE DURING GEAR RETRACTION.  THE CREW SEEMED TO THINK IT WAS ASSOCIATED WITH THE WHEELS SPINNING.  THE AIRCRAFT RETURNED TO CLE AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE BRAKE CONTROL UNIT.  OPERATIONAL CHECKS WERE GOOD.  THE AIRCRAFT WAS TEST FLOWN AND NO DEFETS WERE NOTICED.  THE AIRCRAFT WAS RELEASED FOR SERVICE.
