## Discrepancy

PIT-BWI - FLT 276 - DURING CLIMB-OUT, THERE WAS A BURNING SMELL IN THE PASSENGER CABIN, BUT NO VISIBLE SMOKE.  THE FLIGHT RETURNED TO THE FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE RE-CIRCULATING FAN FILTER.  RAN ENGINES AND AIR CONDITIONING PACKS.  ALL CHECKED NORMAL.  (M)
