Narrative:

ADIZ flight plan filed to EMI, 4000 ft. Turned over to potomac approach and told to continue on course. As I filed to 4000 ft I climbed on that heading to 4000 ft. I was not told to remain clear of class B but I did not hear cleared into class B. To make matters worse, my headset cable came loose and I did not respond to ATC for about 5 mins. Mentally, I was flying IFR. Rarely do I fly VFR and my mindset was IFR. That was wrong as I had not filed IFR. The loose cable was unfortunate at that time. I have 'tis' on my airplane and there was no loss of separation. ATC knew I was EMI direct and filed to 4000 ft, but, that said, I was in error.

Narrative: ADIZ FLT PLAN FILED TO EMI, 4000 FT. TURNED OVER TO POTOMAC APCH AND TOLD TO CONTINUE ON COURSE. AS I FILED TO 4000 FT I CLBED ON THAT HEADING TO 4000 FT. I WAS NOT TOLD TO REMAIN CLR OF CLASS B BUT I DID NOT HEAR CLRED INTO CLASS B. TO MAKE MATTERS WORSE, MY HEADSET CABLE CAME LOOSE AND I DID NOT RESPOND TO ATC FOR ABOUT 5 MINS. MENTALLY, I WAS FLYING IFR. RARELY DO I FLY VFR AND MY MINDSET WAS IFR. THAT WAS WRONG AS I HAD NOT FILED IFR. THE LOOSE CABLE WAS UNFORTUNATE AT THAT TIME. I HAVE 'TIS' ON MY AIRPLANE AND THERE WAS NO LOSS OF SEPARATION. ATC KNEW I WAS EMI DIRECT AND FILED TO 4000 FT, BUT, THAT SAID, I WAS IN ERROR.
