Narrative:

While on a visual approach to casper, wy, we were cleared to land on runway 21. After landing the captain asked me if we had been cleared to land on runway 26 or runway 21, to which I replied '21.' he then asked what runway we were on and we realized that we were on runway 26. We received taxi instructions from the tower for a taxi from runway 26 to the gate with no mention of the mistake. This was a new route for the carrier and from prior experience we had always landed on runway 26 from that side of the casper airport. This may explain why neither crew member caught the mistake, as it seemed to be a normal procedure. Additionally, the captain had just transitioned to the aircraft and was preoccupied with the new procedures required of the aircraft. This was also the last leg of a 4 day flight sequence with each day beginning with an early morning show time and ending at approximately XX00 pm with 7 legs and approximately 5 hours of flight time and 9 hours of duty. Fatigue was a contributing factors. The mistake could have been corrected by a number of actions in my opinion. The exercise of more vigilance by the crew with more crew communication. Tuning in the localizer. A warning or reminder from the tower.

Title: COMMUTER LTT WRONG RWY LNDG.

Narrative: WHILE ON A VISUAL APCH TO CASPER, WY, WE WERE CLRED TO LAND ON RWY 21. AFTER LNDG THE CAPT ASKED ME IF WE HAD BEEN CLRED TO LAND ON RWY 26 OR RWY 21, TO WHICH I REPLIED '21.' HE THEN ASKED WHAT RWY WE WERE ON AND WE REALIZED THAT WE WERE ON RWY 26. WE RECEIVED TAXI INSTRUCTIONS FROM THE TWR FOR A TAXI FROM RWY 26 TO THE GATE WITH NO MENTION OF THE MISTAKE. THIS WAS A NEW RTE FOR THE CARRIER AND FROM PRIOR EXPERIENCE WE HAD ALWAYS LANDED ON RWY 26 FROM THAT SIDE OF THE CASPER ARPT. THIS MAY EXPLAIN WHY NEITHER CREW MEMBER CAUGHT THE MISTAKE, AS IT SEEMED TO BE A NORMAL PROC. ADDITIONALLY, THE CAPT HAD JUST TRANSITIONED TO THE ACFT AND WAS PREOCCUPIED WITH THE NEW PROCS REQUIRED OF THE ACFT. THIS WAS ALSO THE LAST LEG OF A 4 DAY FLT SEQUENCE WITH EACH DAY BEGINNING WITH AN EARLY MORNING SHOW TIME AND ENDING AT APPROX XX00 PM WITH 7 LEGS AND APPROX 5 HRS OF FLT TIME AND 9 HRS OF DUTY. FATIGUE WAS A CONTRIBUTING FACTORS. THE MISTAKE COULD HAVE BEEN CORRECTED BY A NUMBER OF ACTIONS IN MY OPINION. THE EXERCISE OF MORE VIGILANCE BY THE CREW WITH MORE CREW COM. TUNING IN THE LOC. A WARNING OR REMINDER FROM THE TWR.
