Narrative:

En route to bec, beech factory, to select new aircraft. Ict approach gave me a new heading and 'vectors for VOR-B approach.' later gave new heading and 'intercept approach course bec - VOR-B, maintain 3000 ft until established' and I thought she said cleared for VOR-B approach. At 24 DME for ict VOR, I proceeded to go down at FAF. When at 3 mi from airport and at 2200 ft MSL she asked about my altitude, being at 2200 ft MSL. I stated I was cleared for approach and was visual. Another male controller took over and I stated the same. He told me to contact beech tower. I did and landed. I was having trouble with headset and switched to another headset and could only hear out of 1 earpiece. I thought I was cleared for approach. Knowing I was having trouble with headset, I should have verified the clearance. Only the tapes will tell if I was actually cleared for approach. However, if she had intended for me to go to initial approach fix and then reverse course for 24+ mi and do procedure turn, I guess I was subconsciously thinking she would not have said vectors for VOR-B.

Title: SOME CONFUSION EXISTED WITH ATC ABOUT THE APCH PROC FOR AN ATP PLT FLYING THE VOR-B APCH INTO BEC, KS.

Narrative: ENRTE TO BEC, BEECH FACTORY, TO SELECT NEW ACFT. ICT APCH GAVE ME A NEW HDG AND 'VECTORS FOR VOR-B APCH.' LATER GAVE NEW HDG AND 'INTERCEPT APCH COURSE BEC - VOR-B, MAINTAIN 3000 FT UNTIL ESTABLISHED' AND I THOUGHT SHE SAID CLRED FOR VOR-B APCH. AT 24 DME FOR ICT VOR, I PROCEEDED TO GO DOWN AT FAF. WHEN AT 3 MI FROM ARPT AND AT 2200 FT MSL SHE ASKED ABOUT MY ALT, BEING AT 2200 FT MSL. I STATED I WAS CLRED FOR APCH AND WAS VISUAL. ANOTHER MALE CTLR TOOK OVER AND I STATED THE SAME. HE TOLD ME TO CONTACT BEECH TWR. I DID AND LANDED. I WAS HAVING TROUBLE WITH HEADSET AND SWITCHED TO ANOTHER HEADSET AND COULD ONLY HEAR OUT OF 1 EARPIECE. I THOUGHT I WAS CLRED FOR APCH. KNOWING I WAS HAVING TROUBLE WITH HEADSET, I SHOULD HAVE VERIFIED THE CLRNC. ONLY THE TAPES WILL TELL IF I WAS ACTUALLY CLRED FOR APCH. HOWEVER, IF SHE HAD INTENDED FOR ME TO GO TO INITIAL APCH FIX AND THEN REVERSE COURSE FOR 24+ MI AND DO PROC TURN, I GUESS I WAS SUBCONSCIOUSLY THINKING SHE WOULD NOT HAVE SAID VECTORS FOR VOR-B.
