ABSTRACT:
A turbine engine utilizes an oil director to direct any leakage oil from a rear bearing compartment of the turbine engine toward a drain opening for an oil drain. The oil drain is formed in a heat shield located between the low pressure turbine and the exhaust nozzle. The oil drain directs the leakage oil to a benign area of the turbine engine.
