This AD was prompted by a certain combination of conditions, which could cause the fuel spar shutoff valves to remain partially open. We are issuing this AD 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.
