Special Conditions: The Boeing Company (Boeing) Model 747-8 Airplane, Dynamic Test Requirements for Single-Occupant, Oblique (Side- Facing) Seats, With or Without Airbag Devices or 3-Point Restraints

These amended special conditions are issued for the Boeing Model 747-8 airplane. This amendment states that the Boeing Model 747-8 airplane oblique (side-facing) seats may be installed at an angle of 18 to 45 degrees to the airplane centerline and may include a 3-point or airbag restraint system, or both, for occupant restraint and injury protection. Additionally, this amendment changes paragraphs 4 through 8 of the special conditions section. This airplane will have novel or unusual design features when compared to the state of technology envisioned in the airworthiness standards for transport category airplanes. These design features are oblique (side-facing) single- occupant seats equipped with or without airbag devices or 3-point restraints. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for these design features. These special conditions contain the additional safety standards the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards.
