Abstract
Method comprising providing a signal tube extending generally from an engine component disposed on a hot side of a firewall in a gas turbine engine to at least one engine control mechanism disposed on a cool side of the firewall. A fuse in the signal tube is operable responsive to a breach in the signal tube to change from a first condition to a second condition to prevent an over-temperature situation on the cool side of the firewall. The engine control mechanism operates the engine according to a first operating logic utilizing a pressure signal related to a static pressure of a fluid in the signal tube. Loss of the pressure signal causes the engine control mechanism to change to a second operating logic which does not utilize the pressure signal.
