This airplane, as modified by JAMCO America, Inc. (JAMCO), will have a novel or unusual design feature associated with side-facing, oblique seats equipped with inflatable restraints. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for occupants of seats installed at an angle of greater than 18 degrees, but substantially less than 90 degrees, to the centerline of the airplane, nor for airbag devices. 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.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and opportunity for prior public comment on, these special conditions are impracticable because these procedures would significantly delay issuance of the design approval and thus delivery of the affected airplane. The FAA therefore finds that good cause exists for making these special conditions effective upon publication in the Federal Register. Comments Invited We invite interested people to take part in this rulemaking by sending written comments, data, or views. The most helpful comments reference a specific portion of the special conditions, explain the reason for any recommended change, and include supporting data. We will consider all comments we receive by the closing date for comments. We may change these special conditions based on the comments we receive. Background On April 15, 2015, through FAA project no. JAST1977-0, JAMCO applied for a supplemental type certificate to allow the installation of oblique passenger seats, installed at a 43-inch pitch and at an angle of 30 degrees to the vertical plane of the [[Page 13970]] airplane longitudinal centerline, and to include inflatable lap belts, in Boeing Model 777-300ER airplanes. The Boeing Model 777-300ER airplane is a wide-body, swept-wing, conventional-tail, twin-engine, turbofan-powered transport airplane, with seating capacity for 550 passengers. JAMCO proposes the installation of oblique (side-facing) B/E Aerospace Super Diamond business-class seats. These seats will include airbag devices for occupant restraint and injury protection. Type Certification Basis Under the provisions of 14 CFR 21.101, JAMCO America, Inc., must show that the Model 777-300ER airplane, as changed, continues to meet the applicable provisions of the regulations incorporated by reference in type certificate no. T00001SE or the applicable regulations in effect on the date of application for the change. The regulations listed in the type certificate are commonly referred to as the ``original type certification basis.'' The regulations listed in type certificate no. T00001SE are as follows: Sections 25.562 and 25.785; and special conditions no. 25-295-SC for single-occupant, side-facing seats. In addition, the certification basis includes certain special conditions, exemptions, or later amended sections of the applicable part that are not relevant to these special conditions. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Boeing Model 777-300ER airplane because of a novel or unusual design feature, special conditions are prescribed under the provisions of Sec. 21.16. Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate to modify any other model included on the same type certificate to incorporate the same novel or unusual design feature, these special conditions would also apply to the other model under Sec. 21.101. In addition to the applicable airworthiness regulations and special conditions, the Boeing Model 777-300ER airplane must comply with the fuel-vent and exhaust-emission requirements of 14 CFR part 34, and the noise-certification requirements of 14 CFR part 36. The FAA issues special conditions, as defined in 14 CFR 11.19, in accordance with Sec. 11.38, and they become part of the type certification basis under Sec. 21.101. Novel or Unusual Design Features The Boeing Model 777-300ER airplane, as modified by JAMCO will incorporate the following novel or unusual design features: Installation of B/E Aerospace Super Diamond business-class seats manufactured by B/E Aerospace, to be installed at an angle of 30 degrees to the airplane centerline. These seats will include airbag devices for occupant restraint and injury protection. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for occupants of seats installed in the proposed configuration. The seating configuration JAMCO proposes is novel and unusual due to the seat installation at 30 degrees to the airplane centerline, the airbag-system installation, and the seat/occupant interface with the surrounding furniture that introduces occupant alignment and loading concerns. Ongoing research is progressing to establish acceptable occupant- injury limits. Until those limits become available, the FAA proposes a set of interim limits based on the current literature available, current National Highway Traffic Safety Administration (NHTSA) regulations, and preliminary test data from the research program. The existing regulations do not provide adequate or appropriate safety standards for occupants of oblique-angled seats with airbag systems. To provide a level of safety that is equivalent to that afforded occupants of forward- and aft-facing seats, additional airworthiness standards, in the form of special conditions, are necessary. These special conditions supplement part 25 and, more specifically, supplement Sec. Sec. 25.562 and 25.785. The requirements contained in these special conditions consist of both test conditions and injury pass/fail criteria. Discussion Amendment 25-15 to part 25, dated October 24, 1967, introduced the subject of side-facing seats and a requirement that each occupant in a side-facing seat must be protected from head injury by a safety belt and a cushioned rest that will support the arms, shoulders, head, and spine. Subsequently, Amendment 25-20, dated April 23, 1969, clarified the definition of side-facing seats to require that each occupant of a seat that is positioned at more than an 18-degree angle to the vertical plane containing the airplane centerline must be protected from head injury by a safety belt and an energy-absorbing rest that supports the arms, shoulders, head, and spine; or by a safety belt and shoulder harness that prevents the head from contacting injurious objects. The FAA concluded that a maximum 18-degree angle would provide an adequate level of safety based on tests that were performed at the time, and thus adopted that standard. Amendment 25-64, dated June 16, 1988, revised the emergency-landing conditions that must be considered in the design of the airplane. It revised the static-load conditions in Sec. 25.561 and added a new Sec. 25.562, requiring dynamic testing for all seats approved for occupancy during takeoff and landing. The intent was to provide an improved level of safety for occupants on transport-category airplanes. Because most seating on transport-category airplanes is forward-facing, the pass/fail criteria developed in Amendment 25-64 focused primarily on forward-facing seats. Therefore, the testing specified in the rule did not provide a complete measure of occupant injury in seats that are not forward-facing; although Sec. 25.785 does require occupants of all seats that are occupied during taxi, takeoff, and landing not suffer serious injury as a result of the inertia forces specified in Sec. Sec. 25.561 and 25.562. To address recent research findings and accommodate commercial demand, the FAA developed a methodology to address all fully side- facing seats (i.e., seats oriented in the airplane with the occupant facing 90 degrees to the direction of airplane travel) and has documented those requirements in a set of proposed new special conditions. The FAA issued policy statement PS-ANM-25-03-R1 on November 12, 2012, titled, ``Technical Criteria for Approving Side-Facing Seats,'' which conveys the injury criteria to be used in the special conditions. Some of those criteria are applicable to oblique seats but others are not because the motion of an occupant in an oblique seat is different from the motion of an occupant in a fully side-facing seat during emergency landing conditions. For shallower installation angles, the FAA has granted equivalent level of safety (ELOS) findings for oblique seat installations on the premise that an occupant's kinematics in an oblique seat during a forward impact would result in the body aligning with the impact direction. We predicted that the occupant response would be similar to an occupant of a forward-facing seat, and would produce a level of safety equivalent to that of a forward-facing seat. These ELOS findings were subject to many conditions that reflected the injury-evaluation criteria and mitigation strategies available at the time of [[Page 13971]] issuance of the ELOS. However, review of dynamic test results for many of these oblique seat installations raised concerns that the premise was not correct. Potential injury mechanisms exist that are unique to oblique seats and are not mitigated by the ELOS self-alignment approach even if the occupant appears to respond similarly to a forward-facing seat. 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. Applicability As discussed above, these special conditions are applicable to the Boeing Model 777-300ER airplane. These special conditions can be applied to oblique seats installed at an angle greater than 18 degrees but less than 46 degrees to the vertical plane containing the airplane centerline. Should JAMCO apply at a later date for a supplemental type certificate to modify any other model included on type certificate no. T00001SE to incorporate the same novel or unusual design feature, these special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features on one model series of airplanes. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of these features on the airplane. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, because a delay would significantly affect the certification of the airplane, which is imminent, the FAA has determined that prior public notice and comment are unnecessary and impracticable, and good cause exists for adopting these special conditions upon publication in the Federal Register. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above. List of Subjects in 14 CFR Part 25 Aircraft, Aviation safety, Reporting and recordkeeping requirements. The authority citation for these special conditions is as follows: Authority: 49 U.S.C. 106(g), 40113, 44701, 44702, 44704. The Special Conditions Accordingly, pursuant to the authority delegated to me by the Administrator, the following special conditions are issued as part of the type certification basis for the Boeing Model 777-300ER airplane as modified by JAMCO. In addition to the requirements of Sec. 25.562: 1. Head-Injury Criteria Compliance with Sec. 25.562(c)(5) is required, except that, if the anthropomorphic test device (ATD) has no apparent contact with the seat/structure but has contact with an airbag, a head-injury criterion (HIC) unlimited score in excess of 1000 is acceptable, provided the HIC15 score (calculated in accordance with 49 CFR 571.208) for that contact is less than 700. 2. Body-to-Wall/Furnishing Contact If a seat is installed aft of structure (e.g., an interior wall or furnishing) that does not provide a homogenous contact surface for the expected range of occupants and yaw angles, then additional analysis and/or test(s) may be required to demonstrate that the injury criteria are met for the area that an occupant could contact. For example, if different yaw angles could result in different airbag performance, then additional analysis or separate test(s) may be necessary to evaluate performance. 3. Neck Injury Criteria The seating system must protect the occupant from experiencing serious neck injury. The assessment of neck injury must be conducted with the airbag device activated, unless there is reason to also consider that the neck-injury potential would be higher for impacts below the airbag-device deployment threshold. a. The N ij (calculated in accordance with 49 CFR 571.208) must be below 1.0, where Nij = Fz / Fzc + My /Myc , and Nij critical values are: i. Fzc = 1530 lb for tension ii. Fzc = 1385 lb for compression iii. Myc = 229 lb-ft in flexion iv. Myc = 100 lb-ft in extension b. In addition, peak upper-neck Fz must be below 937 lb of tension and 899 lb of compression. c. Rotation of the head about its vertical axis, relative to the torso, is limited to 105 degrees in either direction from forward- facing. d. The neck must not impact any surface that would produce concentrated loading on the neck. 4. Spine and Torso Injury Criteria a. The shoulders must remain aligned with the hips throughout the impact sequence, or support for the upper torso must be provided to prevent forward or lateral flailing beyond 45 degrees from the vertical during significant spinal loading. Alternatively, the lumbar spine tension (Fz ) cannot exceed 1200 lb. b. Significant concentrated loading on the occupant's spine, in the area between the pelvis and shoulders during impact, including rebound, is not acceptable. During this type of contact, the interval for any rearward (X-direction) acceleration exceeding 20g must be less than 3 milliseconds as measured by the thoracic instrumentation specified in 49 CFR part 572, subpart E, filtered in accordance with SAE International (SAE) J211-1. c. Occupant must not interact with the armrest or other seat components in any manner significantly different than would be expected for a forward-facing seat installation. 5. Longitudinal test(s), conducted to measure the injury criteria above, must be performed with the FAA Hybrid III ATD, as described in SAE 1999-01-1609. The test(s) must be conducted with an undeformed floor, at the most-critical yaw case(s) for injury, and with all lateral structural supports (armrests/walls) installed. Note: JAMCO must demonstrate that the installation of seats via plinths or pallets meets all applicable requirements. Compliance with the guidance contained in FAA Policy Memorandum PS-ANM-100- 2000-00123, dated February 2, 2000, titled, ``Guidance for Demonstrating Compliance with Seat Dynamic Testing for Plinths and Pallets,'' is acceptable to the FAA. Inflatable Lap Belt Special Conditions If inflatable lap belts are installed on single-place side-facing seats, the lap belts must meet Special Conditions no. 25-187A-SC.
