Narrative:

Atx had been given heading 210 degree for vector to the visibility runway 24R approach at lax. I reported the runway in sight and was cleared for the visibility approach. I decided to remain on heading 210 degree and intercept the localizer, since simultaneous approachs to runway 24L were in progress. I observed air carrier Y, a twin engine passenger jet (type unknown; engines under wing), closing at 10 O'clock. I informed the tower of the traffic and was told it was for runway 24L. The traffic seemed to be closing at too high a rate, so I was hesitant to take my eyes off it. This resulted in my flying through the localizer for runway 24R before beginning my turn to intercept. In my turn, the tower asked if I had the traffic in sight. I replied that I did. The tower then told me to maintain visibility sep and cleared me to land on runway 24R. My best action in this situation would have been to 'cheat' towards the localizer heading more when I observed the traffic closing too fast.

Title: ATX X FAILED TO COMPLY WITH ATC INSTRUCTIONS. PLTDEV. NMAC.

Narrative: ATX HAD BEEN GIVEN HDG 210 DEG FOR VECTOR TO THE VIS RWY 24R APCH AT LAX. I RPTED THE RWY IN SIGHT AND WAS CLRED FOR THE VIS APCH. I DECIDED TO REMAIN ON HDG 210 DEG AND INTERCEPT THE LOC, SINCE SIMULTANEOUS APCHS TO RWY 24L WERE IN PROGRESS. I OBSERVED ACR Y, A TWIN ENG PAX JET (TYPE UNKNOWN; ENGS UNDER WING), CLOSING AT 10 O'CLOCK. I INFORMED THE TWR OF THE TFC AND WAS TOLD IT WAS FOR RWY 24L. THE TFC SEEMED TO BE CLOSING AT TOO HIGH A RATE, SO I WAS HESITANT TO TAKE MY EYES OFF IT. THIS RESULTED IN MY FLYING THROUGH THE LOC FOR RWY 24R BEFORE BEGINNING MY TURN TO INTERCEPT. IN MY TURN, THE TWR ASKED IF I HAD THE TFC IN SIGHT. I REPLIED THAT I DID. THE TWR THEN TOLD ME TO MAINTAIN VIS SEP AND CLRED ME TO LAND ON RWY 24R. MY BEST ACTION IN THIS SITUATION WOULD HAVE BEEN TO 'CHEAT' TOWARDS THE LOC HDG MORE WHEN I OBSERVED THE TFC CLOSING TOO FAST.
