The FAA's summary their words, unchanged

These special conditions are issued for the Hawker Beechcraft Model No. 400A airplane as modified by Nextant Aerospace. This modification will have a novel or unusual design feature associated with an installed emergency power supply and standby attitude module that use rechargeable lithium batteries and battery systems. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
