FAA 78 FR 52107 PDF

SUMMARY:

This action proposes special conditions for the Boeing Model 777-200, -300, and -300ER series airplanes. These airplanes as modified by the ARINC Aerospace Company will have a novel or unusual design feature, specifically the rechargeable lithium ion batteries and battery system that will be used on an International Communications Group (ICG) ePhone cordless cabin handset. 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 airworthiness standards.
