Narrative:

Cleared for a visual approach for runway 22 at dca. Given a frequency change to tower. Contacted tower and was told (we were told we were #2 for the airport) to square the base turn to provide spacing for B737 landing runway 19. We responded and squared for a 1 mi final being careful to avoid P56 northeast of the airport. We did not receive any other xmissions until we had landed and cleared the runway at taxiway H. After clearing, I heard tower ask if we were still on frequency. I responded that we were and then heard tower call several other aircraft clearing them for takeoff and landing. At that point I noticed flashing green light gun signals coming from the tower. I switched to ground and was unable to contact them on either communication #1 or communication #2. I tried tower on communication #1 and communication #2 and was unable to contact them. We crossed runway 19 and started to taxi toward GA parking and then I tried ground on communication #1 again and we were able to make contact with them. After parking, I spoke with the tower controller and he stated that not only did we not contact them properly after landing, but that we had landing without clearance and were told to go around 3 times. I explained that we did not receive the xmissions. He stated that the B737 was able to hold short of our runway so a serious problem had been avoided. After reviewing the aim and far 91.185, I feel that our decision to continue and land was appropriate. However, earlier recognition of the radio problem could have helped in resolving this before a potential for a runway incursion had developed.

Title: INSTRUCTOR PLT DURING A TRAINING FLT LWOC AND COMMENCED TAXIING WITHOUT CLRNC DUE TO A MALFUNCTIONING COM RADIO.

Narrative: CLRED FOR A VISUAL APCH FOR RWY 22 AT DCA. GIVEN A FREQ CHANGE TO TWR. CONTACTED TWR AND WAS TOLD (WE WERE TOLD WE WERE #2 FOR THE ARPT) TO SQUARE THE BASE TURN TO PROVIDE SPACING FOR B737 LNDG RWY 19. WE RESPONDED AND SQUARED FOR A 1 MI FINAL BEING CAREFUL TO AVOID P56 NE OF THE ARPT. WE DID NOT RECEIVE ANY OTHER XMISSIONS UNTIL WE HAD LANDED AND CLRED THE RWY AT TXWY H. AFTER CLRING, I HEARD TWR ASK IF WE WERE STILL ON FREQ. I RESPONDED THAT WE WERE AND THEN HEARD TWR CALL SEVERAL OTHER ACFT CLRING THEM FOR TKOF AND LNDG. AT THAT POINT I NOTICED FLASHING GREEN LIGHT GUN SIGNALS COMING FROM THE TWR. I SWITCHED TO GND AND WAS UNABLE TO CONTACT THEM ON EITHER COM #1 OR COM #2. I TRIED TWR ON COM #1 AND COM #2 AND WAS UNABLE TO CONTACT THEM. WE CROSSED RWY 19 AND STARTED TO TAXI TOWARD GA PARKING AND THEN I TRIED GND ON COM #1 AGAIN AND WE WERE ABLE TO MAKE CONTACT WITH THEM. AFTER PARKING, I SPOKE WITH THE TWR CTLR AND HE STATED THAT NOT ONLY DID WE NOT CONTACT THEM PROPERLY AFTER LNDG, BUT THAT WE HAD LWOC AND WERE TOLD TO GO AROUND 3 TIMES. I EXPLAINED THAT WE DID NOT RECEIVE THE XMISSIONS. HE STATED THAT THE B737 WAS ABLE TO HOLD SHORT OF OUR RWY SO A SERIOUS PROB HAD BEEN AVOIDED. AFTER REVIEWING THE AIM AND FAR 91.185, I FEEL THAT OUR DECISION TO CONTINUE AND LAND WAS APPROPRIATE. HOWEVER, EARLIER RECOGNITION OF THE RADIO PROB COULD HAVE HELPED IN RESOLVING THIS BEFORE A POTENTIAL FOR A RWY INCURSION HAD DEVELOPED.
