The FAA's summary their words, unchanged

This amended special condition is being issued for incorporation of an electronic flight instrument system (EFIS) and autopilot flight director system in the Beech Model B300 and 1900D Series airplanes. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of electronic displays and autopilot flight director system and the protection of them from indirect effects of lightning for which the applicable regulations do not contain adequate or appropriate airworthiness standards. This amended special condition, concerning the indirect effects of lightning, contains the additional safety standards which the Administrator considers necessary to establish a level of safety equivalent to that provided by the applicable airworthiness standards.
