## Discrepancy

ON FLIGHT 4586 THE CREW REPORTED THAT DURING DESCENT INTO LGA NOTICED AN OVERHEAT/AIR BURNING SMELL IN THE COCKPIT.   THE AIRCRAFT WAS REMOVED FROM SERVICE.  PERFORMED HIGH POWER ENGINE RUNS & CHECKED AIR CIRCULATION MACHINE’S FROM ALL BLEED SOURCES.  MAINTENANCE COULD NOT DUPLICATE THE ODOR.  CHECKED INLETS & EXHAUST FOR EVIDENCE OF OIL, NONE NOTED.  THE AIRCRAFT WAS RETURNED TO SERVICE.
