## Discrepancy

MDT - FLT 6021 THE CREW REPORTED A LOUD NOISE INFLIGHT UNDER FLOOR ASSOCIATED WITH PACK NR 2.  THEY ALSO REPORTED A CABIN PRESSURE DROP.  THE AIRCRAFT DIVERTED INTO CLE AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND RECONNECTED THE DUCT ON NR 2 PACK SYSTEM BETWEEN THE AIR CYCLE MACHINE AND HEAT EXCHANGER.  OPERATIONAL CHECKS WERE GOOD.
