Pilot of an sel small aircraft overshot the localizer during vector to final causing approach controller to subsequently break off the attempted approach and vector reporter to a higher altitude for another approach. ATC also advised that the reporter was tracking 20 degrees off assigned heading and had overshot assigned altitude. Reporter blamed turbulence for not being able to hold altitude and his compass being off for his tracking error.

Narrative:
I asked socal for the ILS into palomar. I was vectored towards the approach and was to remain VFR at 7000 ft. At this time I estimated I was third in the sequence. ATC then lost contact with a seneca, an emergency on the approach. Approximately 5 or 6 airplanes, including myself, were then vectored away from the area. I was vectored for 10-15 mins, then vectored to the approach, first to 5000 ft then to 3500 ft cleared for the approach. In the turbulence I had a hard time with my altitude and subsequently flew through the localizer. ATC then gave me a heading and a climb to 5000 ft. I climbed through 5000 ft and was contacted that I was above assigned altitude. My altimeter read under 5300 ft. ATC also asked my heading. My directional gyro corresponded to assigned heading as did my compass. ATC said he was tracking me 20 degrees off and asked for a 20 degree correction. At this time I was in VMC conditions so with my heading off 20 degrees with a possible directional gyro/compass problem and my problem holding altitude, I canceled IFR and landed VFR.
Original NASA ASRS Text
Title: PLT OF AN SEL SMA OVERSHOT THE LOC DURING VECTOR TO FINAL CAUSING APCH CTLR TO SUBSEQUENTLY BREAK OFF THE ATTEMPTED APCH AND VECTOR RPTR TO A HIGHER ALT FOR ANOTHER APCH. ATC ALSO ADVISED THAT THE RPTR WAS TRACKING 20 DEGS OFF ASSIGNED HDG AND HAD OVERSHOT ASSIGNED ALT. RPTR BLAMED TURB FOR NOT BEING ABLE TO HOLD ALT AND HIS COMPASS BEING OFF FOR HIS TRACKING ERROR.
Narrative: I ASKED SOCAL FOR THE ILS INTO PALOMAR. I WAS VECTORED TOWARDS THE APCH AND WAS TO REMAIN VFR AT 7000 FT. AT THIS TIME I ESTIMATED I WAS THIRD IN THE SEQUENCE. ATC THEN LOST CONTACT WITH A SENECA, AN EMER ON THE APCH. APPROX 5 OR 6 AIRPLANES, INCLUDING MYSELF, WERE THEN VECTORED AWAY FROM THE AREA. I WAS VECTORED FOR 10-15 MINS, THEN VECTORED TO THE APCH, FIRST TO 5000 FT THEN TO 3500 FT CLRED FOR THE APCH. IN THE TURB I HAD A HARD TIME WITH MY ALT AND SUBSEQUENTLY FLEW THROUGH THE LOC. ATC THEN GAVE ME A HDG AND A CLB TO 5000 FT. I CLBED THROUGH 5000 FT AND WAS CONTACTED THAT I WAS ABOVE ASSIGNED ALT. MY ALTIMETER READ UNDER 5300 FT. ATC ALSO ASKED MY HDG. MY DIRECTIONAL GYRO CORRESPONDED TO ASSIGNED HDG AS DID MY COMPASS. ATC SAID HE WAS TRACKING ME 20 DEGS OFF AND ASKED FOR A 20 DEG CORRECTION. AT THIS TIME I WAS IN VMC CONDITIONS SO WITH MY HDG OFF 20 DEGS WITH A POSSIBLE DIRECTIONAL GYRO/COMPASS PROB AND MY PROB HOLDING ALT, I CANCELED IFR AND LANDED VFR.
