## Discrepancy

AIRCRAFT WAS GROUNDED: DURING DESENT FLIGHT CREW STARTED TO SMELL AN ODOR SIMILIAR TO HYDRAULIC FLUID OR CRAYONS. CREW TURNED THE CABIN FAN OFF AND THE BLOWER, EXTRACT FAN WAAS PLACED IN THE OVERIDE POSITION WHICH GREATLY REDUCED THE ODOR. MAINTENANCE ISOLATED THE SOURCE OF THE ODOR TO THE APU DUE TO FINDING OIL LEAKS. **SUPPLEMENTAL REPORT WILL BE SUBMITTED** (OPEN)
