This Directive requires inspecting to determine if certain motor-operated shutoff valve actuators for the fuel tanks are installed together with related investigative and corrective actions as necessary.  The Directive also requires revising the AWL section of the Instructions for Continued Airworthiness.
             The Directive results from a design review of the fuel tank systems and is issued to prevent electrical energy from lightning, hot shorts or fault current from entering the fuel tank through the MOV actuator shaft, which could result in fuel tank explosions and consequent loss of the aeroplane.
