PVT PLT LOSES SITUATIONAL AWARENESS WHILE CONDUCTING AN ILS APCH TO IDA.

Narrative

I WAS FLYING FROM OGDEN TO REXBURG AND THE RPTED VISIBILITY WAS 9 MI WITH CEILINGS OF 500 FT. I FLEW TOWARDS RXE AND DECIDED THAT I WOULD PREFER TO USE THE ILS IN IDA. I CALLED CTR AND REQUESTED AN IFR APCH. I ACCEPTED VECTORS TO INTERCEPT AND MADE THE MISTAKE OF NOT KEYING UP THE ILS FREQ. WHEN THE CTLR INFORMED ME THAT I HAD FLOWN THROUGH THE LOC; I QUICKLY RESET THE RADIO AND RECAPTURED THE LOC WITH THE CTLR'S VECTOR. BY DOING THAT TO STABILIZE THE APCH; I FINALLY HAD A FULL DEFLECTION OF THE GS INDICATOR AT APPROX 5600 FT. I CALLED FOR A MISSED APCH AND THEN STARTED A R CLBING TURN. WITH THE DISTR; I STILL HADN'T KEYED UP THE VOR FOR THE MISSED; AND WAS INFORMED BY CTR THAT I WAS GOING TOO FAR E. THEY CLRED A CLB TO 10000 FT AND I TUNED IN THE VOR AND THEY CLRED ME TO MAKE ANOTHER APCH. I TRACKED OUTBOUND ON 023 DEG RADIAL; MADE THE PROC TURN AND MADE THE APCH AND LANDED. THE 2 MAJOR FACTORS WERE WITH THE FIRST MISTAKE. I SHOULD HAVE REQUESTED A FULL APCH AGAIN WITH THE PROC TURN TO HAVE TIM NECESSARY TO SET EVERYTHING UP PROPERLY. THE SECOND FACTOR WAS THAT I HAD NEVER MADE AN APCH INTO IDAHO FALLS AND THAT UNFAMILIARITY ALONG WITH THE FIRST MISTAKE BEGAN TO COMPOUND. I HAVE SINCE MET WITH AN INSTRUCTOR AND GONE OVER THE APCH TO REVIEW APCH PROCS.
