## Discrepancy

AS AC PULLED OFF RUNWAY AFTER LANDING THE CA AND FO NOTED A BURNING SMELL. IT ONLY LASTED ABOUT 15 SECONDS BUT THEN THE FA'S CALLED SAYING IT SMELLED LIKE BURNING RUBBER AND THERE WAS A HAZE IN THE CABIN. PACKS WERE ON ENG BLEEDS AT THE TIME, SOURCE OF SMOKE NOT OBVIOUS AT TIME. PERHAPS PREVIOUS A/C TIRE SMOKE? PERFORMED INSPECTION PER WORK CARD 0550-2002. RAN BOTH ENGINES AND APU AS PNEUMATIC SOURCES ISOLATED EACH. COULD NOT DUPLICATE ODOR. COORDINATED WITH MCC AND REMOVED AND REPLACED BOTH RECIRCULATION FILTERS PER A321 AMM 21-21. (LP# 9480260)
