Special Conditions: Airbus, Model A340-600 Series Airplanes; Lower Deck Crew Rest Compartments

These special conditions are issued for the Airbus Model A340 series airplanes. These airplanes, as modified by Flight Structures, Inc., will have a novel or unusual design feature associated with the installation of lower deck crew rest (LDCR) compartments. The LDCR compartment is novel in terms of part 25 in that it will be located under the passenger cabin floor in the aft cargo compartment of Airbus Model A340-200 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.
