A method for assembling a gas turbine engine to prevent rotor over-speeding is described. The method includes serially coupling a first fuel system interface to a second fuel system interface, such that at least one of the first fuel system interface and the second fuel system interface is coupled to the gas turbine engine. The method also includes coupling a control system to the first fuel system interface and to the second fuel system interface. The control system is configured to identify an occurrence of an over-speed condition. The method also includes programming the control system to discontinue fuel flow to the engine when both the first fuel system interface and the second fuel system interface indicate an over-speed condition has occurred.

Methods and systems to facilitate over-speed protection

A method for assembling a gas turbine engine is described. The method includes coupling a first fuel system interface (FSI-1) to a second fuel system interface (FSI-2), and coupling one of the FSI-1 and the FSI-2 to the engine. The method includes coupling a first control system and a second control system to the FSI-1 and to the FSI-2. The first control system includes a first driver A and a second driver A, and the second control system includes a first driver B and a second driver B. The method includes configuring the first control system and the second control system to apply a first over-speed logic algorithm and a second over-speed logic algorithm to determine operation of the first driver A, the second driver A, the first driver B, and the second driver B.
