Narrative:
I was wbound on V2 near yqg when I was instructed by ATC to descend to 4000 ft and take a heading of 245 degrees. I did that. After about 5 mins at 245 degrees, I confirmed heading with controller, and then lost radio contact with ATC. I continued on the assigned heading and altitude. After I cleared the class B airspace, I was able to contact flight watch (122.0) and asked them to cancel IFR. Then I was able to contact lansing radio to confirm IFR cancellation. They confirmed cancellation and asked me to phone detroit ATC center after landing. Detroit ATC said they had to divert acrs because I had gone through approach corridor while on my last assigned heading and altitude. I do not know why radio contact was lost. Speculation: pilot error, but I'm not sure. Radios worked without problem on subsequent trips. A checklist of appropriate action in the event of radio failure might have solved the problem.

Title: PLT OF AN SMA SEL HAS LOST COMS ON IFR FLT PLAN AND CONTINUES ON LAST HDG CAUSING ATC TO DIVERT OTHER TFC WHEN HE PENETRATED CLASS B AIRSPACE.
Narrative: I WAS WBOUND ON V2 NEAR YQG WHEN I WAS INSTRUCTED BY ATC TO DSND TO 4000 FT AND TAKE A HDG OF 245 DEGS. I DID THAT. AFTER ABOUT 5 MINS AT 245 DEGS, I CONFIRMED HDG WITH CTLR, AND THEN LOST RADIO CONTACT WITH ATC. I CONTINUED ON THE ASSIGNED HDG AND ALT. AFTER I CLRED THE CLASS B AIRSPACE, I WAS ABLE TO CONTACT FLT WATCH (122.0) AND ASKED THEM TO CANCEL IFR. THEN I WAS ABLE TO CONTACT LANSING RADIO TO CONFIRM IFR CANCELLATION. THEY CONFIRMED CANCELLATION AND ASKED ME TO PHONE DETROIT ATC CTR AFTER LNDG. DETROIT ATC SAID THEY HAD TO DIVERT ACRS BECAUSE I HAD GONE THROUGH APCH CORRIDOR WHILE ON MY LAST ASSIGNED HDG AND ALT. I DO NOT KNOW WHY RADIO CONTACT WAS LOST. SPECULATION: PLT ERROR, BUT I'M NOT SURE. RADIOS WORKED WITHOUT PROB ON SUBSEQUENT TRIPS. A CHKLIST OF APPROPRIATE ACTION IN THE EVENT OF RADIO FAILURE MIGHT HAVE SOLVED THE PROB.
