## Discrepancy

AFTER RAISING THE LANDING GEAR, THERE APPEARED TO BE A HIGHER THAN NORMAL NOISE AND VIBRATION ORIGINATING UNDER THE FLIGHT DECK BUT NO ABNORMAL INDICATIONS AT THAT TIME.  AFTER ONE HOUR IN FLIGHT, CREW RECEIVED 4 AMBER XX'S ON ECAM WHEEL PAGE.  AN EMERGENCY WAS DECLARED AS A PRECAUTION AND THE AIRCRAFT LANDED IN PHL WITHOUT INCIDENT.  AFTER PARKING AT GATE, 'L/G SYS DISAGREE' MESSAGE ON ECAM.  MAINTENANCE ACCOMPLISHED FUNCTIONAL TEST OF THE EXTENSION / RETRACTION SYSTEM AND CHECK OF NLG DOOR GAPS WITH NO PROBLEMS FOUND.  VISUAL INSPECTION OF FUSELAGE, ACCESS DOORS AND PANELS OK.  NO FAULTS FOUND.
