This AD was prompted by a report indicating that an airplane lost the integrated standby instrument system (ISIS), then, during the same flight, lost all electronic instrument system (EIS) display units. The FAA is issuing this AD to prevent loss of the ISIS, which, if combined with loss of all EIS display units, could reduce the flightcrew's situational awareness and contribute to loss of control of the airplane or impact with obstacles or terrain.
