Narrative:

I entered the arsa from the north and was cleared by bwi approach to enter at 4500 ft. I was approximately 37 mi to the north. I had received the ATIS report, no problem. At approximately 20 mi out I heard bursts of static on the radio and mixed with someone saying they were having transmission problems I had expected to hear from approach. I changed radios and got the same bursts of static. I changed frequencys to another known approach frequency and got no response. I tried to transmit on all radios and I then thought it must be my microphone button because I heard no check, so I got out my hand held microphone. At this time I was approximately 12 mi out, near glen left martin airport which is on a 12 mi arc from bwi. I turned left staying that far out on an arc. Ahead I could see an airliner which was going to cross my path at the same height, so I stayed at that position, circled and dropped to 3500 ft. At this time my LORAN flashed stating malfunction. My ammeter read 2000, and my radio lights started to dim. I exited the arsa to the east staying approximately 12 mi out, flew over to the eastern shore at 3000 ft. At this time I assessed my situation -- no electrics. I had to extend my gears by emergency procedure. A plane flew close to me (3000 ft) while I was checking this out (out of the arsa) and I made a hard left turn out of the way. I dropped my gears at this altitude and I landed at bay bridge -- no flaps either -- no electrics.

Title: AN SMA PLT HAD A COMPLETE ELECTRICAL FAILURE WHILE IN AN ARSA. THEN THE PLT HAD A CONFLICT WHILE SOLVING THE ELECTRICAL PROBLEM OUTSIDE THE ARSA.

Narrative: I ENTERED THE ARSA FROM THE N AND WAS CLRED BY BWI APCH TO ENTER AT 4500 FT. I WAS APPROX 37 MI TO THE N. I HAD RECEIVED THE ATIS RPT, NO PROBLEM. AT APPROX 20 MI OUT I HEARD BURSTS OF STATIC ON THE RADIO AND MIXED WITH SOMEONE SAYING THEY WERE HAVING XMISSION PROBLEMS I HAD EXPECTED TO HEAR FROM APCH. I CHANGED RADIOS AND GOT THE SAME BURSTS OF STATIC. I CHANGED FREQS TO ANOTHER KNOWN APCH FREQ AND GOT NO RESPONSE. I TRIED TO XMIT ON ALL RADIOS AND I THEN THOUGHT IT MUST BE MY MIKE BUTTON BECAUSE I HEARD NO CHK, SO I GOT OUT MY HAND HELD MIKE. AT THIS TIME I WAS APPROX 12 MI OUT, NEAR GLEN L MARTIN ARPT WHICH IS ON A 12 MI ARC FROM BWI. I TURNED L STAYING THAT FAR OUT ON AN ARC. AHEAD I COULD SEE AN AIRLINER WHICH WAS GOING TO CROSS MY PATH AT THE SAME HEIGHT, SO I STAYED AT THAT POS, CIRCLED AND DROPPED TO 3500 FT. AT THIS TIME MY LORAN FLASHED STATING MALFUNCTION. MY AMMETER READ 2000, AND MY RADIO LIGHTS STARTED TO DIM. I EXITED THE ARSA TO THE E STAYING APPROX 12 MI OUT, FLEW OVER TO THE EASTERN SHORE AT 3000 FT. AT THIS TIME I ASSESSED MY SITUATION -- NO ELECTRICS. I HAD TO EXTEND MY GEARS BY EMER PROC. A PLANE FLEW CLOSE TO ME (3000 FT) WHILE I WAS CHKING THIS OUT (OUT OF THE ARSA) AND I MADE A HARD L TURN OUT OF THE WAY. I DROPPED MY GEARS AT THIS ALT AND I LANDED AT BAY BRIDGE -- NO FLAPS EITHER -- NO ELECTRICS.
