Narrative:

Turbulence flight in IFR. Clearance for ILS 23R approach. Tuned in parallel ILS 23L localizer. Approach vectors to ILS 23R were given. I intercepted and flew in on 23L. Perhaps approach could have reconfirmed localizer frequency when they saw us go through the 23R localizer approach course. Factors: if I wasn't getting bumped around in moderate turbulence I probably would have been more attentive to the frequency.

Title: PLT OF SMA FLEW WRONG LOCALIZER APCH AFTER VECTOR FOR ILS.

Narrative: TURB FLT IN IFR. CLRNC FOR ILS 23R APCH. TUNED IN PARALLEL ILS 23L LOC. APCH VECTORS TO ILS 23R WERE GIVEN. I INTERCEPTED AND FLEW IN ON 23L. PERHAPS APCH COULD HAVE RECONFIRMED LOC FREQ WHEN THEY SAW US GO THROUGH THE 23R LOC APCH COURSE. FACTORS: IF I WASN'T GETTING BUMPED AROUND IN MODERATE TURB I PROBABLY WOULD HAVE BEEN MORE ATTENTIVE TO THE FREQ.
