## Discrepancy

AIRCRAFT WAS NOT GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO SJD DUE TO THE FLIGHT CREW REPORTING A FORWARD CARGO DOOR ECAM MESSAGE DISPLAYED SHORTLY AFTER GEAR RETRACTION. THE AIRCRAFT LANDED SAFELY AT SJD WITHOUT FURTHER INCIDENT. MAINTENANCE THE CLEARANCE BETWEEN THE TARGET AND PROXIMITY SWITCH 30WV WAS OUT OF TOLERANCE FOR THE FORWARD CARGO DOOR AND ADJUSTED THE CLEARANCE PER AMM 52-71-00. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO FAULTS NOTED.
