## Discrepancy

ASH FLT 7043 IAD-LGA - AIRCRAFT RETURNED TO THE FIELD.  CREW DID NOT DECLARE AN EMERGENCY BUT ATC DID.  PASSENGERS WERE NOT BRACED AND LANDING WAS NORMAL AND NOT OVERWEIGHT.  CREW REPORTED GETTING A GEAR DISAGREE WARNING MESSAGE AND THAT MLG EICAS INDICATION WAS GOING FROM GREEN TO YELLOW REPEATEDLY.  A PASSENGER REPORTED THE SOUND OF REPEAT BANGING IN THE FLOOR AREA.  MX REPLACED THE MAIN LANDING GEAR SELECTOR VALVE.
