Narrative:
Dca approach control cleared the aircraft for the river visibility approach to runway 36. We responded and flew the approach. When we were on short final, we realized that the controller never told us to contact the tower. We then attempted to contact the tower, but did not get a response. At that point we were approximately 100' AGL and determined that the safest course of action was to land, traffic permitting. After landing we contacted ground control on radio #1 and received a response and clearance to taxi. Shortly thereafter, ground control complained about a stuck microphone on the frequency. We determined that radio #2 (in use during approach) was not working properly.
Original NASA ASRS Text
Title: FLT CREW OF LTT COMMUTER ON SHORT FINAL REALIZED APCH HAD NOT CLEARED THE FLT TO TWR NOR HAD TWR GIVEN LNDG CLRNC. FLT LANDED WITHOUT CLRNC. DISCOVERED ON GND FREQ THEY HAD A STUCK MICROPHONE ON THEIR #2 TRANSMITTER.
Narrative: DCA APCH CTL CLRED THE ACFT FOR THE RIVER VIS APCH TO RWY 36. WE RESPONDED AND FLEW THE APCH. WHEN WE WERE ON SHORT FINAL, WE REALIZED THAT THE CTLR NEVER TOLD US TO CONTACT THE TWR. WE THEN ATTEMPTED TO CONTACT THE TWR, BUT DID NOT GET A RESPONSE. AT THAT POINT WE WERE APPROX 100' AGL AND DETERMINED THAT THE SAFEST COURSE OF ACTION WAS TO LAND, TFC PERMITTING. AFTER LNDG WE CONTACTED GND CTL ON RADIO #1 AND RECEIVED A RESPONSE AND CLRNC TO TAXI. SHORTLY THEREAFTER, GND CTL COMPLAINED ABOUT A STUCK MIC ON THE FREQ. WE DETERMINED THAT RADIO #2 (IN USE DURING APCH) WAS NOT WORKING PROPERLY.
