Narrative:

While en route to sbn on a VFR cross country flight, I contacted south bend approach control and requested a practice ILS approach to runway 27. Approach issued radar vectors to intercept the localizer and after I was established inbound told me to contact sbn tower. Upon contacting the tower I gave my position as outside norna. My actual position was outside misha. The tower didn't respond so after the radio was clear I again gave my position as outside norna because I still hadn't heard the OM signal since my marker beacon recover had not been turned on. When the tower did respond, the transmission was broken up beyond recognition. I asked the tower to say again my instructions but again transmission was broken up. By this time I realized how close to the runway I was and not being certain I was clear to land, I decided to go around which I announced to the tower, also informing them that I was switching to my #2 radio. As I was executing the go around, I noticed another aircraft landing on runway 27 which, had I continued to land, the 2 aircraft would have been dangerously close. I was able to clearly receive the tower on my #2 radio. I was then instructed to contact approach control. I requested approach for another practice ILS. I was given radar vectors. At this time I noticed my marker beacon receiver was off and also my error on position reporting. I corrected both and successfully completed the approach. The factors that contributed to this situation were my inattn to the approach plate. Due to the fact that I was VFR I casually glanced at the approach and misread the OM fix name. This, along with the marker beacon receiver being off, are the major contributing factors. The #1 radio was functioning properly while I was communicating with approach control. I don't know what caused the reception problem with the tower but this complicated the situation. Although I am still in instrument training I now realize how important it is to be aware of your exact position even in VFR conditions. I will also treat every practice approach like an actual instrument approach and not allow myself to become complacent just because I'm being radar vectored.

Title: GA SMA FAILED TO COMPLETE A PRACTICE IAP ILS APCH BECAUSE THE PLT FAILED TO FOLLOW THE APCH PROC, DID NOT USE THE MARKER RECEIVER, AND MISIDENTED HIS POS WHEN CALLING THE TWR.

Narrative: WHILE ENRTE TO SBN ON A VFR XCOUNTRY FLT, I CONTACTED S BEND APCH CTL AND REQUESTED A PRACTICE ILS APCH TO RWY 27. APCH ISSUED RADAR VECTORS TO INTERCEPT THE LOC AND AFTER I WAS ESTABLISHED INBOUND TOLD ME TO CONTACT SBN TWR. UPON CONTACTING THE TWR I GAVE MY POS AS OUTSIDE NORNA. MY ACTUAL POS WAS OUTSIDE MISHA. THE TWR DIDN'T RESPOND SO AFTER THE RADIO WAS CLR I AGAIN GAVE MY POS AS OUTSIDE NORNA BECAUSE I STILL HADN'T HEARD THE OM SIGNAL SINCE MY MARKER BEACON RECOVER HAD NOT BEEN TURNED ON. WHEN THE TWR DID RESPOND, THE XMISSION WAS BROKEN UP BEYOND RECOGNITION. I ASKED THE TWR TO SAY AGAIN MY INSTRUCTIONS BUT AGAIN XMISSION WAS BROKEN UP. BY THIS TIME I REALIZED HOW CLOSE TO THE RWY I WAS AND NOT BEING CERTAIN I WAS CLR TO LAND, I DECIDED TO GAR WHICH I ANNOUNCED TO THE TWR, ALSO INFORMING THEM THAT I WAS SWITCHING TO MY #2 RADIO. AS I WAS EXECUTING THE GAR, I NOTICED ANOTHER ACFT LNDG ON RWY 27 WHICH, HAD I CONTINUED TO LAND, THE 2 ACFT WOULD HAVE BEEN DANGEROUSLY CLOSE. I WAS ABLE TO CLRLY RECEIVE THE TWR ON MY #2 RADIO. I WAS THEN INSTRUCTED TO CONTACT APCH CTL. I REQUESTED APCH FOR ANOTHER PRACTICE ILS. I WAS GIVEN RADAR VECTORS. AT THIS TIME I NOTICED MY MARKER BEACON RECEIVER WAS OFF AND ALSO MY ERROR ON POS RPTING. I CORRECTED BOTH AND SUCCESSFULLY COMPLETED THE APCH. THE FACTORS THAT CONTRIBUTED TO THIS SITUATION WERE MY INATTN TO THE APCH PLATE. DUE TO THE FACT THAT I WAS VFR I CASUALLY GLANCED AT THE APCH AND MISREAD THE OM FIX NAME. THIS, ALONG WITH THE MARKER BEACON RECEIVER BEING OFF, ARE THE MAJOR CONTRIBUTING FACTORS. THE #1 RADIO WAS FUNCTIONING PROPERLY WHILE I WAS COMMUNICATING WITH APCH CTL. I DON'T KNOW WHAT CAUSED THE RECEPTION PROBLEM WITH THE TWR BUT THIS COMPLICATED THE SITUATION. ALTHOUGH I AM STILL IN INST TRAINING I NOW REALIZE HOW IMPORTANT IT IS TO BE AWARE OF YOUR EXACT POS EVEN IN VFR CONDITIONS. I WILL ALSO TREAT EVERY PRACTICE APCH LIKE AN ACTUAL INST APCH AND NOT ALLOW MYSELF TO BECOME COMPLACENT JUST BECAUSE I'M BEING RADAR VECTORED.
