This AD was prompted by reports of the brief but total loss of all liquid crystal display (LCD) units during cruise on airplanes equipped with a certain EIS2 standard of electronic instrument system. The FAA is issuing this AD to provide procedures to the flightcrew to restore operation of these LCD units and prevent prolonged loss of critical flight information to the flightcrew and the consequent reduced ability of the flightcrew to control the airplane during adverse flight conditions.
