Special Conditions: Learjet Model 35, 35A, 36, and 36A Airplanes; Rechargeable Lithium-Ion Batteries and Battery Systems [FR DOC# 2013-24727] SUMMARY: This action proposes special conditions for the Learjet Model 35, 35A, 36, and 36A airplanes. These airplanes, as modified by Peregrine, 13000 E. Control Tower Road, Unit K-4, Englewood, CO, 80112, will have a novel or unusual design feature associated with rechargeable lithium-ion batteries and battery systems. These batteries 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 large transport-category airplanes. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These proposed 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
