FLC LINES UP WITH CLOSED RWY.

Narrative

1 MONTH AGO I FLEW INTO PSP AND RWY 13L/R WERE CLOSED. THE CTR TXWY WAS NOW THE RWY 12. ON THIS TRIP I LOOKED AT THE FACILITY RPT BUT DID NOT SEE THE NOTAM FOR RWY 12 CLOSED. I CHKED OUR COMMERCIAL PUBLICATION AND IT STILL HAD RWY 12 LISTED IN IT. THE CAPT AND I TALKED ABOUT IT AND HE DIDN'T KNOW EITHER IF RWY 13R WAS CLOSED. HE ALSO MISSED THE NOTAM. IN OUR MINDS WE PLANNED TO LAND ON RWY 12 AT PSP. THE ATIS AT PSP SAID RWY 13; NOTHING ABOUT RWY 12 CLOSED OR RWY 13R OPEN. AS WE TURNED FINAL I LOOK AT RWY 13R AND THOUGHT WHEN ARE THEY GOING TO OPEN THAT? THE CAPT THEN REMINDED ME THAT WE WERE LNDG ON THE CTR RWY 12. AS WE FLEW TO IT THE TWR SAW WE HAD LINED UP ON RWY 12 NOT RWY 13R AND TOLD US TO GAR. AT THE SAME TIME I SAW THE LIGHTED CROSS COME OUT OF THE RWY END MARKERS. WE DID A NORMAL GAR AND LANDED ON RWY 13R. I KNOW WE ARE SUPPOSED TO CATCH THESE THINGS ON PREFLT. BUT A NOTICE ON ATIS WOULD ALSO BE OF HELP WHEN RWY OR TXWYS ARE CLOSED OR OPENED AFTER A PERIOD OF TIME. ALSO I THINK THAT THE RWY SHOULD BE MARKED BETTER THAN THIS WAS WITH A LIGHTED BAR OR CROSS PARKED ON END OF RWY. IT DID NOT SHOW UP UNTIL ABOUT 1 1/2 MI OUT. ALSO THE TWR MAKING THE ATIS COULD HAVE PUT RWY 13R NOT JUST RWY 13. THIS MAY HAVE HELPED. THE BOTTOM LINE IS WE MISSED THE NOTAM AND RELIED ON WHAT WE HAD BEEN DOING FOR SEVERAL MONTHS.
