Narrative:

On initial contact with approach control, I advised them that I was approaching mid channel (a fix that we use to identify with). At this time, the controller advised that I continue inbound. He later asked for my position in relation to the koko head VOR which I gave to him. I continued inbound 'without receiving clearance to enter class B airspace.' in the vicinity of the airport, a controller asked if I was on frequency. I replied that I was and he cleared me for runway 4L and told me to contact the tower. I contacted the tower and was told that I was now cleared for runway 4R. I landed without incident and ground told me to call the tower supervisor. I spoke with the supervisor and he informed me that they hadn't cleared me to enter the airspace and if I remembered the controller asking me to report over koko head (which I didn't). I then realized that I hadn't received clearance and apologized when I realized my mistake. He told me that it was their fault also for not giving me a new squawk code (I was xferred by center) but that I needed to be careful and listen for the clearance. I teach my students the importance of this all the time but I myself forgot! I realize the importance of paying attention and communicating clearly with ATC. The fact that they hadn't given me a squawk code justified nothing. I should have waited until I heard the words 'cleared to enter class B airspace' before I continued inbound.

Original NASA ASRS Text

Title: PLT OF A C172 FAILED TO RECEIVE CLRNC PRIOR TO ENTERING CLASS B AIRSPACE DUE TO A MISUNDERSTANDING OF CONVERSATION WITH THE APCH CTLR PRIOR TO ENTERING THE AIRSPACE.

Narrative: ON INITIAL CONTACT WITH APCH CTL, I ADVISED THEM THAT I WAS APCHING MID CHANNEL (A FIX THAT WE USE TO IDENT WITH). AT THIS TIME, THE CTLR ADVISED THAT I CONTINUE INBOUND. HE LATER ASKED FOR MY POS IN RELATION TO THE KOKO HEAD VOR WHICH I GAVE TO HIM. I CONTINUED INBOUND 'WITHOUT RECEIVING CLRNC TO ENTER CLASS B AIRSPACE.' IN THE VICINITY OF THE ARPT, A CTLR ASKED IF I WAS ON FREQ. I REPLIED THAT I WAS AND HE CLRED ME FOR RWY 4L AND TOLD ME TO CONTACT THE TWR. I CONTACTED THE TWR AND WAS TOLD THAT I WAS NOW CLRED FOR RWY 4R. I LANDED WITHOUT INCIDENT AND GND TOLD ME TO CALL THE TWR SUPVR. I SPOKE WITH THE SUPVR AND HE INFORMED ME THAT THEY HADN'T CLRED ME TO ENTER THE AIRSPACE AND IF I REMEMBERED THE CTLR ASKING ME TO RPT OVER KOKO HEAD (WHICH I DIDN'T). I THEN REALIZED THAT I HADN'T RECEIVED CLRNC AND APOLOGIZED WHEN I REALIZED MY MISTAKE. HE TOLD ME THAT IT WAS THEIR FAULT ALSO FOR NOT GIVING ME A NEW SQUAWK CODE (I WAS XFERRED BY CTR) BUT THAT I NEEDED TO BE CAREFUL AND LISTEN FOR THE CLRNC. I TEACH MY STUDENTS THE IMPORTANCE OF THIS ALL THE TIME BUT I MYSELF FORGOT! I REALIZE THE IMPORTANCE OF PAYING ATTN AND COMMUNICATING CLRLY WITH ATC. THE FACT THAT THEY HADN'T GIVEN ME A SQUAWK CODE JUSTIFIED NOTHING. I SHOULD HAVE WAITED UNTIL I HEARD THE WORDS 'CLRED TO ENTER CLASS B AIRSPACE' BEFORE I CONTINUED INBOUND.
