Narrative:

While on right downwind to runway 24R at lax approach asked if we had a commuter on base leg for runway 24L in sight. We replied that we had it and the airport in sight. ATC then cleared us for the visibility 24R approach and to follow and not pass the commuter for runway 24L. At that time we wrote down the runway (24R) that we were cleared for and dialed and tuned in the localizer runway 24R. As we turned right base for runway 24R approach advised us to follow and not pass the commuter and that we may turn to the left if necessary. As the commuter turned right base to final for runway 24L we also turned right base to final for runway 24R. The commuter appeared to be overshooting runway 24L and was making a steep turn back towards the runway. As he was turning back we were lining up on final for runway 24R. At this time the commuter continued to turn towards us and below and appeared to line up for runway 24R, our runway. At this point I turned to the right and parallel the course for runway 24R, and passed him since he was not flying towards us. At no time did we notice visly and backed up by the localizer runway 24R at lax that we overshot final for runway 24R. The commuter advised ATC that we had passed him and that we were above and ahead of him against ATC clearance. There then seemed to be some confusion on the radio between the commuter and ATC as to which runway the commuter and our flight were supposed to be on. We checked our notes to double check that we had been cleared for the visibility runway 24R at lax. As I also slowed my aircraft to minimum approach speed to let the commuter catch up and pass us. Once the commuter passed well below and to our left I continued with a normal approach to runway 24R at lax. A key factor to this whole situation were the strong northwest winds aloft that blew the commuter across final for runway 24L, and for the commuter's appeared confusion to which runway he was cleared for. The commuter did do a good job once on final to remain on centerline and no further problems evolved.

Title: ON VISUAL APCH TO LAX REPORTER WAS CLRED TO FOLLOW ANOTHER ACFT AND NOT PASS AS THEY FLEW APCHS TO PARALLEL RWYS. REPORTER FAILED TO COMPLY.

Narrative: WHILE ON R DOWNWIND TO RWY 24R AT LAX APCH ASKED IF WE HAD A COMMUTER ON BASE LEG FOR RWY 24L IN SIGHT. WE REPLIED THAT WE HAD IT AND THE ARPT IN SIGHT. ATC THEN CLRED US FOR THE VIS 24R APCH AND TO FOLLOW AND NOT PASS THE COMMUTER FOR RWY 24L. AT THAT TIME WE WROTE DOWN THE RWY (24R) THAT WE WERE CLRED FOR AND DIALED AND TUNED IN THE LOC RWY 24R. AS WE TURNED R BASE FOR RWY 24R APCH ADVISED US TO FOLLOW AND NOT PASS THE COMMUTER AND THAT WE MAY TURN TO THE L IF NECESSARY. AS THE COMMUTER TURNED R BASE TO FINAL FOR RWY 24L WE ALSO TURNED R BASE TO FINAL FOR RWY 24R. THE COMMUTER APPEARED TO BE OVERSHOOTING RWY 24L AND WAS MAKING A STEEP TURN BACK TOWARDS THE RWY. AS HE WAS TURNING BACK WE WERE LINING UP ON FINAL FOR RWY 24R. AT THIS TIME THE COMMUTER CONTINUED TO TURN TOWARDS US AND BELOW AND APPEARED TO LINE UP FOR RWY 24R, OUR RWY. AT THIS POINT I TURNED TO THE R AND PARALLEL THE COURSE FOR RWY 24R, AND PASSED HIM SINCE HE WAS NOT FLYING TOWARDS US. AT NO TIME DID WE NOTICE VISLY AND BACKED UP BY THE LOC RWY 24R AT LAX THAT WE OVERSHOT FINAL FOR RWY 24R. THE COMMUTER ADVISED ATC THAT WE HAD PASSED HIM AND THAT WE WERE ABOVE AND AHEAD OF HIM AGAINST ATC CLRNC. THERE THEN SEEMED TO BE SOME CONFUSION ON THE RADIO BTWN THE COMMUTER AND ATC AS TO WHICH RWY THE COMMUTER AND OUR FLT WERE SUPPOSED TO BE ON. WE CHKED OUR NOTES TO DOUBLE CHK THAT WE HAD BEEN CLRED FOR THE VIS RWY 24R AT LAX. AS I ALSO SLOWED MY ACFT TO MINIMUM APCH SPD TO LET THE COMMUTER CATCH UP AND PASS US. ONCE THE COMMUTER PASSED WELL BELOW AND TO OUR L I CONTINUED WITH A NORMAL APCH TO RWY 24R AT LAX. A KEY FACTOR TO THIS WHOLE SITUATION WERE THE STRONG NW WINDS ALOFT THAT BLEW THE COMMUTER ACROSS FINAL FOR RWY 24L, AND FOR THE COMMUTER'S APPEARED CONFUSION TO WHICH RWY HE WAS CLRED FOR. THE COMMUTER DID DO A GOOD JOB ONCE ON FINAL TO REMAIN ON CTRLINE AND NO FURTHER PROBS EVOLVED.
