## Abstract

These special conditions are issued for the Bombardier Inc. Model BD-100-1A10 airplane. This airplane, as modified by S4A, Solutions for Aviation, S.L., 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 the installation of an Aspire 200 satellite communications (satcom) system with wireless handsets that use rechargeable lithium batteries and battery systems. Rechargeable lithium batteries and battery systems have certain failure, operational, and maintenance characteristics that differ significantly from those of the nickel- cadmium and lead-acid rechargeable batteries currently approved for installation on transport category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. 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.
