NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.

THE REGULARLY SCHEDULED AIR CARRIER FLIGHT WAS CLIMBING TO ALTITUDE WHEN THE ENGINE OIL PRESSURE AND QUANTITY DROPPED TO ZERO ON THE #3 ENGINE; IT WAS SHUT DOWN. SHORTLY THEREAFTER, THE #1 ENGINE OIL PRESSURE DROPPED TO ZERO. IT WAS REDUCED TO IDLE AND THE FLIGHT DIVERTED AND EXECUTED NORMAL LANDING. THE #3 ENGINE LOST OIL DUE TO A FAILED OIL PRESSURE TUBE TO THE # 6 BEARING. THE #1 ENGINE LOST OIL DUE TO OIL CONTAMINATION WITH HYDRAULIC FLUID. INTERVIEWS WITH AMERICAN AIRLINES AND CONTRACT MAINTENANCE PERSONNEL THAT HAD SERVICED THE ACFT WITHIN THE PREVIOUS 30 DAYS REVEALED NO DISCREPANCIES THAT WOULD HAVE ALLOWED HYDRAULIC FLUID TO ENTER THE OIL SYSTEM. THE #3 ENG OIL PRESSURE TUBE WAS LOST IN TRANSIT BY AAL FREIGHT PRESONNEL SO IT COULD NOT BE EXAMINED.
