Narrative:
During cruise at FL350 on iad-stl flight. Left engine oil quantity began falling rapidly. When oil pressure gauge and annunciator indicated loss of operating pressure left engine was shut down. Flight emergency was declared and flight diverted to cmh where day landing occurred without incident. Callback conversation with reporter revealed the following information: reporter stated the aircraft was powered with P&west JT8D-9 engines and the loss of oil was caused by a broken internal turbine bearing supply tube. He said depending on what stage of the turbine section was involved it could be an engine change or a simple repair.

Title: A DC9-32 IN CRUISE DECLARED AN EMER AND DIVERTED DUE TO LOSS OF OIL IN #1 ENG CAUSED BY A BROKEN INTERNAL BEARING SUPPLY LINE.
Narrative: DURING CRUISE AT FL350 ON IAD-STL FLT. L ENG OIL QUANTITY BEGAN FALLING RAPIDLY. WHEN OIL PRESSURE GAUGE AND ANNUNCIATOR INDICATED LOSS OF OPERATING PRESSURE L ENG WAS SHUT DOWN. FLT EMER WAS DECLARED AND FLT DIVERTED TO CMH WHERE DAY LNDG OCCURRED WITHOUT INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THE ACFT WAS POWERED WITH P&W JT8D-9 ENGS AND THE LOSS OF OIL WAS CAUSED BY A BROKEN INTERNAL TURBINE BEARING SUPPLY TUBE. HE SAID DEPENDING ON WHAT STAGE OF THE TURBINE SECTION WAS INVOLVED IT COULD BE AN ENG CHANGE OR A SIMPLE REPAIR.
