## Abstract

These special conditions are issued for the Airbus Model A330- 300 and Model A330-900 series airplanes. These airplanes, as modified by TTF Aerospace, LLC (TTF Aerospace), 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 a lower deck mobile crew rest (LD-MCR) compartment installed in the aft cargo compartment of Model A330–300 and Model A330-900 series airplanes. 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.
