## Discrepancy

AIRCRAFT WAS GROUNDED: ON DESCENT AN ODOR BEGAN ON THE FLIGHT DECK. IT SEEMED TO DISSIPATE AND THEN RE-APPEAR. IT HAD A MUSTY SMOKEY ODOR THE FLIGHT ATTENDANTS REPORTED IT AS WELL. AFTER DEPLANING IT WAS STRONGEST MID-CABIN. APU BLEED WAS ON AT THIS TIME. MAINTENANCE FOUND THE APU TO BE THE SOURCE OF THE ODOR DUE TO AN INTERNAL OIL LEAK. **SUPPLEMENTAL REPORT WILL BE SUBMITTED** (OPEN)
