Narrative:

While cruising at FL330, lost radio contact with ZOB. After trying numerous frequencys, could not contact any center, ZID, ZOB, or ZDC. We were previously cleared direct to a point on the westminster 3 arrival at bwi. After mgw VOR, there is a crossing restr at mumsy intersection which puts the aircraft at 15000 ft for a normal descent to land at bwi. Reaching the arrival point, we still could not contact anyone. We squawked 7600 on the transponder and started a normal descent on the arrival to 15000 ft, as per the FARS on lost communication. During the descent, prior to reaching mumsy intersection, I was able to contact pittsburgh radio on frequency 121.5. I told them our location and intentions. They told us to standby, then they gave us 2 frequencys to contact ZDC and baltimore approach. It appeared at this time the radio started to work again. No luck on the first frequency. The second frequency we contacted washington. We were instructed to send an identify and continue descent to 15000 ft. Then at this time, we were told 'radar contact, squawk previous code and continue descent.' after that all communications and procedures were normal operations. Neither approach or center said I needed to contact them on the ground at bwi and said nothing of the procedures we used for the temporary loss of communications. From that point on, all radios appeared to operate normally. On the return flight to dayton, I asked ZDC and ZOB if they had any communication problems but they did not know of any. All following operations were uneventful. In this situation, I believe I followed the FARS to the letter, tried to communicate the best and all ways possible, and still operate and maintain safe operations in a very congested east coast.

Title: LOST COM IN A B727. RPTR TRIED VARIOUS FREQS AND 3 DIFFERENT AIR TFC FACILITIES BEFORE RE-ESTABLISHING COMS. FLC FOLLOWED LOST COM PROCS.

Narrative: WHILE CRUISING AT FL330, LOST RADIO CONTACT WITH ZOB. AFTER TRYING NUMEROUS FREQS, COULD NOT CONTACT ANY CENTER, ZID, ZOB, OR ZDC. WE WERE PREVIOUSLY CLRED DIRECT TO A POINT ON THE WESTMINSTER 3 ARR AT BWI. AFTER MGW VOR, THERE IS A XING RESTR AT MUMSY INTXN WHICH PUTS THE ACFT AT 15000 FT FOR A NORMAL DSCNT TO LAND AT BWI. REACHING THE ARR POINT, WE STILL COULD NOT CONTACT ANYONE. WE SQUAWKED 7600 ON THE XPONDER AND STARTED A NORMAL DSCNT ON THE ARR TO 15000 FT, AS PER THE FARS ON LOST COM. DURING THE DSCNT, PRIOR TO REACHING MUMSY INTXN, I WAS ABLE TO CONTACT PITTSBURGH RADIO ON FREQ 121.5. I TOLD THEM OUR LOCATION AND INTENTIONS. THEY TOLD US TO STANDBY, THEN THEY GAVE US 2 FREQS TO CONTACT ZDC AND BALTIMORE APCH. IT APPEARED AT THIS TIME THE RADIO STARTED TO WORK AGAIN. NO LUCK ON THE FIRST FREQ. THE SECOND FREQ WE CONTACTED WASHINGTON. WE WERE INSTRUCTED TO SEND AN IDENT AND CONTINUE DSCNT TO 15000 FT. THEN AT THIS TIME, WE WERE TOLD 'RADAR CONTACT, SQUAWK PREVIOUS CODE AND CONTINUE DSCNT.' AFTER THAT ALL COMS AND PROCS WERE NORMAL OPS. NEITHER APCH OR CTR SAID I NEEDED TO CONTACT THEM ON THE GND AT BWI AND SAID NOTHING OF THE PROCS WE USED FOR THE TEMPORARY LOSS OF COMS. FROM THAT POINT ON, ALL RADIOS APPEARED TO OPERATE NORMALLY. ON THE RETURN FLT TO DAYTON, I ASKED ZDC AND ZOB IF THEY HAD ANY COM PROBS BUT THEY DID NOT KNOW OF ANY. ALL FOLLOWING OPS WERE UNEVENTFUL. IN THIS SIT, I BELIEVE I FOLLOWED THE FARS TO THE LETTER, TRIED TO COMMUNICATE THE BEST AND ALL WAYS POSSIBLE, AND STILL OPERATE AND MAINTAIN SAFE OPS IN A VERY CONGESTED EAST COAST.
