## Discrepancy

THE CREW REPORTED JUST AFTER LEVELING AT FL 360 THEY HEARD & FELT A LOUD THUMP UNDER THE COCKPIT FLOORBOARD.  THE ACFT DID NOT GIVE ANY AN INDICATION OF A MALFUNCTION , BUT THE CREW HEARD THE THUMP AGAIN.  THE CREW DIVERTED SO THAT MX COULD INSPECT THE ACFT.  THE ACFT LANDED WITHOUT INCIDENT.  THE ACFT WAS REMOVED FROM SERVICE.  R & R THE NR 2 PROX SWITCH ON RT MLG UPLOCK IAW AMM 32-61-01.  THE FUNCTIONAL CHECK WAS GOOD IAW AMM 32-63-05.  THE ACFT WAS RETURNED TO SERVICE.
