Narrative:
I was given clearance for an ILS approach to runway 14. I flew through the course and had no indication of the localizer. I was rerted and given clearance for a second ILS approach to runway 14, flew through the course, and had no localizer indication. At that time due to equipment failure of the #1 and #2 navigation units, I requested and received a no-gyro surveillance approach to runway 14. The first approach ended in a missed approach due to too far right of course. The second approach ended with a full stop landing runway 14.

Title: EQUIPMENT PROBLEM ON ILS APCH. ACFT DOES A MISSED APCH, REQUESTS NO GYRO SURVEILLANCE APCH.
Narrative: I WAS GIVEN CLRNC FOR AN ILS APCH TO RWY 14. I FLEW THROUGH THE COURSE AND HAD NO INDICATION OF THE LOC. I WAS RERTED AND GIVEN CLRNC FOR A SECOND ILS APCH TO RWY 14, FLEW THROUGH THE COURSE, AND HAD NO LOC INDICATION. AT THAT TIME DUE TO EQUIP FAILURE OF THE #1 AND #2 NAV UNITS, I REQUESTED AND RECEIVED A NO-GYRO SURVEILLANCE APCH TO RWY 14. THE FIRST APCH ENDED IN A MISSED APCH DUE TO TOO FAR RIGHT OF COURSE. THE SECOND APCH ENDED WITH A FULL STOP LNDG RWY 14.
