What the agency says
These special conditions are issued for the Airbus Defense and Space S.A. (Airbus) Model C-212-CB, C-212-CC, C-212-CD, C-212-CE, C- 212-CF, and C-212-DF airplanes. These airplanes, as modified by Xtreme Avionics, LLC (Xtreme), will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a rechargeable lithium-ion battery for backup power of the GI 275 Standby Display. 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.
