## Discrepancy

ON FLIGHT 4333, THE CREW REPORTED THAT AFTER TAKEOFF AND GEAR RETRACTION THEY HEARD AN UNUSUAL NOISE AND RECEIVED A CONTINUOUS LEFT MAIN GEAR IN TRANSIT INDICATION ON EICAS.  THE CREW DECLARED AN EMERGENCY, COMPLETED AOM VOL 1 CHECKLIST AND RETURNED TO JFK.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS REMOVED FROM SERVICE.  REMOVED AND REPLACED THE PROXIMITY SWITCH IAW EMB-145 AMM 32-61-01.  THE OPERATIONAL CHECK PER 32-63-05 WAS GOOD, NO DEFECT NOTED.  THE AIRCRAFT WAS RETURNED TO SERVICE.
