Narrative:
During approach and below 1;000 ft AGL; the first officer experienced a stuck microphone resulting in a loss of communication. No landing clearance had yet been issued. In order to avoid a go-around into class B airspace in IMC conditions without communication; I instructed the first officer to squawk 7600. At 500 ft AGL; we received the proper light gun signals; verified that the runway was clear; and landed without further disruption. We were NORDO from about 1;000 ft AGL until taxiing clear of the runway. We assessed the problem on the ground and were able to re-establish communication with ground control.
