## Discrepancy

AIRCRAFT WAS GROUNDED: ON DESCEND OUT 6000, WE SMELLED A VERY STRONG, PUGNANT ODOR. MAINTENANCE FOUND THE APU TO BE THE SOURCE OF THE ODOR DUE TO OIL LEAKING FROM THE WITNESS DRAIN LINE AND THE INSIDE OF THE PLENUM WAS COATED WITH OIL. **SUPPLEMENTAL REPORT WILL BE SUBMITTED** (OPEN)
