Special Conditions: The Boeing Company (Boeing), Model 777 Series Airplanes; Dynamic Test Requirements for Single Occupant Oblique Seats, With or Without Airbag Devices or 3-Point Restraints

These amended special conditions are issued for the Boeing Model 777 series airplanes. These special conditions are for oblique (side-facing) seats, installed in Boeing Model 777 series airplanes, at an angle of 18 to 45 degrees to the airplane centerline and which may include a 3-point or airbag restraint system, or both, for occupant restraint and injury protection. This amendment adds a note and one special condition to 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 passenger seats equipped with or without airbag devices or 3-point restraints. 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.
