Narrative

ON LNDG IN TO ZZZ; OUR ACFT GOT AN ANTISKID MASTER CAUTION THAT ILLUMINATED FOR A COUPLE OF SECONDS AND THEN WENT OUT. THIS WAS SOMEWHAT EXPECTED BECAUSE THE CAPT WAS PERFORMING A XWIND LNDG; AND THIS MASTER CAUTION COMES ON OFTEN DUE TO THE LOGIC OF THE ANTISKID COMPUTER. BECAUSE THE LIGHT WENT OUT; WE TAXIED TO THE RAMP AND SUSPECTED THERE WAS NOTHING WRONG WITH THE ACFT. AFTER THE PAX WERE OFF THE ACFT; I PERFORMED A POSTFLT INSPECTION AND SECURED THE PROPS WITH THE APPROPRIATE STRAPS. LATER IN THE EVENING UPON REACHING OUR HOTEL; I WAS NOTIFIED THAT ONE OF THE GND CREW WORKERS IN ZZZ1 DISCOVERED THAT OUR ACFT WAS MISSING ITS R OUTER MAIN TIRE AND WHEEL. I HAD FAILED TO IDENT THIS DURING MY POSTFLT INSPECTION. THERE WERE NO INJURIES OR DAMAGE TO PROPERTY AS A RESULT OF THIS INCIDENT. THE TIRE WAS DISCOVERED AT OUR DEP ARPT (ZZZ) AND HAD APPARENTLY SEPARATED FROM THE ACFT DURING TKOF. FACTORS THAT CONTRIBUTED TO MY OVERSIGHT AND FAILING TO IDENT THE MISSING WHEEL ON MY POSTFLT INSPECTION ARE AS FOLLOWS: 1) NIGHTTIME; AND NOT USING A FLASHLIGHT ON POSTFLT. 2) FATIGUE; IT WAS THE LAST FLT OF THE NIGHT AND I HAD BEEN ON DUTY FOR 9 HRS AND FLOWN 6 HRS. 3) PERSONAL ISSUES IN MY PVT LIFE WERE A DISTR TO ME MENTALLY. AS A RESULT OF THIS; I WILL ALWAYS USE A FLASHLIGHT ON NIGHT POSTFLTS. I WILL ALSO UTILIZE BETTER CRM AND NOTIFY MY CAPT THAT I DO HAVE PERSONAL INFLUENCES OUTSIDE OF OUR PROFESSION THAT MAY INTERFERE WITH MY PROFICIENCY. I WILL ALSO SHARE THE IMPORTANCE OF A THOROUGH AND COMPLETE POSTFLT INSPECTION AFTER EVERY FLT WITH MY COLLEAGUES.
