Special Conditions: The Boeing Company, Boeing Model 747-8 Series Airplane; Short-Term Occupancy of Lower Lobe During Flight and Installation of Stairway Between Main Deck and Lower-Lobe
Abstract
These special conditions are issued for the The Boeing Company (Boeing) Model 747-8 series airplane. This airplane, as modified by Boeing, 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 stairs for flightcrew to access the forward and aft lower lobe compartments during flight. These compartments will have two main functions: storage of service items and that of a Class C cargo compartment. 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.
