## Abstract

These special conditions are issued for the Boeing 737-600/- 700/-700C/-800/-900 and -900ER Series airplanes (hereafter referred to as "Boeing 737NG"). These airplanes, as modified by the Boeing Company, will have a novel or unusual design feature associated with the installation of rechargeable lithium batteries and rechargeable lithium-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.
