Special Conditions: L-3 Communications Integrated Systems, Boeing Model 747-8 Series Airplanes; Therapeutic Oxygen for Medical Use

These special conditions are issued for the Boeing Model 747-8 series airplanes. These airplanes, as modified by L-3 Communications Integrated Systems (L-3 Communications), 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 therapeutic oxygen for medical use installed in an executive-interior airplane. 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.
