## Discrepancy

AROUND 10000 FT CREW HEARD A BANG AND THEN SMELLED AND SAW SMOKE.  CREW DECLARED AND EMERGENCY AND ELECTED TO RETURN TO DEPARTURE WHERE THEY LANDED WITHOUT INCIDENT. MAINTENANCE INSPECTED AND FOUND PACK 1 ACM LOCKED UP.  MAINTENANCE PLACED PACK 1 ON MEL IAW AMM AND ACFT IS GOOD FOR SERVICE.
