Narrative

DEPARTED IPSWICH (PVT STRIP; MA 47) ON PLEASURE FLT TO NEW BEDFORD; MASS; (EWB) IN NAVION. WX CAVU. CONTACTED BOS APCH ON 124.4 AFTER TKOF. GIVEN DISCREET XPONDER CODE. CLRED TO PROCEED AT LEAST 12 MI E OF BOS AT 2500 FT TO AVOID CTL ZONE. ADVISED MY ONLY TFC A JUMBO JET AT; I THINK; 8 O'CLOCK AT 10;000 FT DSNDING TO LAND AT BOS. WAS THEN TOLD TO SWITCH TO 120.6; WHICH I DID. COULDN'T RAISE ANYONE SO I WENT BACK TO 124.4 WITH NO LUCK. THEN TRIED 119.1 AND 121.9 ON DIFFERENT RADIOS ALL WITH THE SAME RESULT -- SILENCE. OBVIOUSLY THE TROUBLE WAS WITH ME. I SUSPECTED A COM NAV MASTER SWITCH. BY THEN THE JET HAD PASSED WELL UNDER ME; L TO R; SO PERTINENT TFC WAS OUT OF THE WAY. FOLLOWING WHAT I BELIEVED TO BE THE PROPER PROC; I CONTINUED ON MY FLT PLAN BY DEAD RECKONING WHILE TRYING ALL THE SWITCHES ON MY COM/NAV CONSOLE AND CHKING FUSES AND CIRCUIT BREAKERS; ALL THE TIME IN CAVU CONDITIONS. I FOLLOWED THE COASTLINE SE AT 2500 FT TO PLYMOUTH; OUTSIDE BOSTON'S CTL ZONE; CLBED A BIT; HEADED FOR NEW BEDFORD; AND; JUST IN CASE; TRIED LISTENING FOR THEIR ATIS. AS I SPOTTED THE ARPT AHEAD; AND HAD ABOUT DECIDED TO LAND AT NEARBY NON-TWR FALL RIVER; THE ATIS CAME IN LOUD AND CLR; AS DID THE TWR ON 118.1. GND CTL REQUESTED THAT I CALL A BOS PHONE NUMBER; WHICH; AS I SUSPECTED; WAS FAA APCH CTL. I WAS GIVEN A POLITE BUT FIRM LECTURE FROM A LADY WHO SAID I HAD PASSED NEARLY 6 MI CLOSER TO BOS THAN I WAS SUPPOSED TO. I APOLOGIZED; AND DESCRIBED MY APPARENTLY TEMPORARY RADIO FAILURE. THE FLT HOME THE NEXT DAY WAS ROUTINE; EXCEPT THAT I ELECTED A 17 MI CLRNC TO THE E PASSING BOS; JUST IN CASE. NEEDLESS TO SAY; I HAVE A DATE TOMORROW WITH MY ACFT RADIO SHOP.
