This AD results from two reports of inadequate clearance between the bus bars in the DA-A panel. We are issuing this AD to prevent insufficient electrical isolation for the electrical bus configuration and inability of the flightcrew to isolate the bus bars in an emergency situation involving a dual generator failure, which could result in extra loads on the main ship batteries and consequent loss of power to the main essential bus.
