Abstract
A method of deactivating a liquid distribution system of a gas turbine engine in the event of a fire condition includes introducing a quantity of air into the liquid distribution system at a location upstream of a liquid pump of the liquid distribution system. The quantity of air is greater than a liquid discharge capacity of the liquid pump, thereby starving the liquid pump.
