Narrative:

Flight en route was VFR on top at 3000' with tops at 1300 to 1600'. Anc was IFR with RVR fluctuating, visibility 1/2 mi. I was sequenced for the ILS approach to 6R. I shot the approach and missed. Went around for second ILS approach. Inside the OM I was given the 6R RVR of 1600'. I told tower that I would continue for a look, but that I needed 1800' RVR. I continued the approach, had the runway in sight at minimums, but went missed approach because of the 1600' RVR. The RVR continued to drop. I was placed in holding pattern with 2 other aircraft. I was first in line for the approach; however, one of the other aircraft was put first in line because of his fuel situation. He shot the approach and made it. RVR was up to 1800'. One of my coworkers was in the holding pattern also. Earlier in the morning I had talked to my wife on the phone and told her that I had made a missed approach. She expressed surprise. I include this as a possible contributing factor as it may have been a subtle pressure not to miss the approach. I also believe that having my coworker on the approach 3 mi behind me was contributing to the pressure of not to miss. I was lined up on both the localizer and the G/south. I went into the scud at 1300'. Prelndg and landing checklist completed. At the MM I had looked up and out for the runway; I saw nothing. I then noticed that my airspeed had decayed to less than what I would have liked for this approach, and also that the localizer needle was to the right. I started to increase power. At the im I saw nothing. As I continued to 'hunt' for the runway, the localizer needle deflected further to the right. At this point I made my error of not initiating a missed approach. At no point was I at or below the DH of 324'; however, I had continued past the missed approach point. I was 'hunting' for the runway. T/D RVR was 1800', I can't remember the midfield, and rollout RVR was greater than 6000'. This expectation of better visibility kept me looking. I spotted a runway light and went for it, powering back and setting up for a landing. The runway came in sight and I landed. It was the wrong runway; I had landed on 6L. I talked with the tower supervisor later on the landline. We were both concerned as to what had transpired. ATC had several complaints of needle fluctuations on the ILS. He also told me that 2 weeks earlier an air carrier jet had done the same thing, except that he saw that it was 6L that he was about to land on and went around. The tower supervisor also told me that the lights for 6R were off, and the lights for 6L were on! I feel that this was a contributing factor. I realize my mistake of not going missed approach at the proper time. My stupidity cost me my job. I won't ever make that mistake again!

Title: FLYING AN IAP-ILS APCH TO RWY 6R AT ANC WITH MINIMUM RVR, ATX PLT FLEW PAST THE MISSED APCH POINT AT MINIMUM ALT LOOKING FOR THE RWY AND THEN LANDED ON 6L. ERROR COST HIM HIS JOB.

Narrative: FLT ENRTE WAS VFR ON TOP AT 3000' WITH TOPS AT 1300 TO 1600'. ANC WAS IFR WITH RVR FLUCTUATING, VISIBILITY 1/2 MI. I WAS SEQUENCED FOR THE ILS APCH TO 6R. I SHOT THE APCH AND MISSED. WENT AROUND FOR SECOND ILS APCH. INSIDE THE OM I WAS GIVEN THE 6R RVR OF 1600'. I TOLD TWR THAT I WOULD CONTINUE FOR A LOOK, BUT THAT I NEEDED 1800' RVR. I CONTINUED THE APCH, HAD THE RWY IN SIGHT AT MINIMUMS, BUT WENT MISSED APCH BECAUSE OF THE 1600' RVR. THE RVR CONTINUED TO DROP. I WAS PLACED IN HOLDING PATTERN WITH 2 OTHER ACFT. I WAS FIRST IN LINE FOR THE APCH; HOWEVER, ONE OF THE OTHER ACFT WAS PUT FIRST IN LINE BECAUSE OF HIS FUEL SITUATION. HE SHOT THE APCH AND MADE IT. RVR WAS UP TO 1800'. ONE OF MY COWORKERS WAS IN THE HOLDING PATTERN ALSO. EARLIER IN THE MORNING I HAD TALKED TO MY WIFE ON THE PHONE AND TOLD HER THAT I HAD MADE A MISSED APCH. SHE EXPRESSED SURPRISE. I INCLUDE THIS AS A POSSIBLE CONTRIBUTING FACTOR AS IT MAY HAVE BEEN A SUBTLE PRESSURE NOT TO MISS THE APCH. I ALSO BELIEVE THAT HAVING MY COWORKER ON THE APCH 3 MI BEHIND ME WAS CONTRIBUTING TO THE PRESSURE OF NOT TO MISS. I WAS LINED UP ON BOTH THE LOC AND THE G/S. I WENT INTO THE SCUD AT 1300'. PRELNDG AND LNDG CHKLIST COMPLETED. AT THE MM I HAD LOOKED UP AND OUT FOR THE RWY; I SAW NOTHING. I THEN NOTICED THAT MY AIRSPD HAD DECAYED TO LESS THAN WHAT I WOULD HAVE LIKED FOR THIS APCH, AND ALSO THAT THE LOC NEEDLE WAS TO THE RIGHT. I STARTED TO INCREASE PWR. AT THE IM I SAW NOTHING. AS I CONTINUED TO 'HUNT' FOR THE RWY, THE LOC NEEDLE DEFLECTED FURTHER TO THE RIGHT. AT THIS POINT I MADE MY ERROR OF NOT INITIATING A MISSED APCH. AT NO POINT WAS I AT OR BELOW THE DH OF 324'; HOWEVER, I HAD CONTINUED PAST THE MISSED APCH POINT. I WAS 'HUNTING' FOR THE RWY. T/D RVR WAS 1800', I CAN'T REMEMBER THE MIDFIELD, AND ROLLOUT RVR WAS GREATER THAN 6000'. THIS EXPECTATION OF BETTER VISIBILITY KEPT ME LOOKING. I SPOTTED A RWY LIGHT AND WENT FOR IT, POWERING BACK AND SETTING UP FOR A LNDG. THE RWY CAME IN SIGHT AND I LANDED. IT WAS THE WRONG RWY; I HAD LANDED ON 6L. I TALKED WITH THE TWR SUPVR LATER ON THE LANDLINE. WE WERE BOTH CONCERNED AS TO WHAT HAD TRANSPIRED. ATC HAD SEVERAL COMPLAINTS OF NEEDLE FLUCTUATIONS ON THE ILS. HE ALSO TOLD ME THAT 2 WKS EARLIER AN ACR JET HAD DONE THE SAME THING, EXCEPT THAT HE SAW THAT IT WAS 6L THAT HE WAS ABOUT TO LAND ON AND WENT AROUND. THE TWR SUPVR ALSO TOLD ME THAT THE LIGHTS FOR 6R WERE OFF, AND THE LIGHTS FOR 6L WERE ON! I FEEL THAT THIS WAS A CONTRIBUTING FACTOR. I REALIZE MY MISTAKE OF NOT GOING MISSED APCH AT THE PROPER TIME. MY STUPIDITY COST ME MY JOB. I WON'T EVER MAKE THAT MISTAKE AGAIN!
