Special Conditions: Cessna Aircraft Company, Models 208 and 208B, Caravan Airplanes; As Modified by Peregrine; Installation of Rechargeable Lithium Battery

These special conditions are issued for the Cessna Aircraft Company, Models 208 and 208B Caravan airplanes. This airplane, as modified by Peregrine, will have a novel or unusual design feature associated with the use of a replacement option of a lithium battery instead of nickel-cadmium (Ni-Cd) and lead-acid rechargeable batteries. 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.
