| Background: | This Directive requires the installation of a jumper wire between the wiring of the fire extinguisher switch and the fuel shutoff switch for each engine. The Directive is issued to prevent a latent open circuit that could leave the fuel spar shutoff valve in a partially open position when the engine fire switch is activated, which could result in fuel from the engine feeding an uncontrolled fire in the engine or the strut. |
