Action
Notice of proposed special conditions.
Summary
This action proposes special conditions for Boeing Model 787-9 series airplanes. These airplanes, as modified by NAT, 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 high wall suites in the passenger cabin. 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.
