Abstract

A method of operating a gas turbine engine powerplant 10 for an aircraft is disclosed. Various construction details are developed which decrease the temperature of failed components to decrease maintenance time for the aircraft engine. In one particular embodiment, the method includes the step of increased cooling of the engine oil at the end of the cruise operative condition and at the beginning of idle descent to overcool oil and components in contact with the oil during the descent mode of the aircraft.
