FOR FURTHER INFORMATION CONTACT: Alan Sinclair, FAA, Airframe and Cabin 
Safety, ANM-115, Transport Airplane Directorate, Aircraft Certification 
Service, 1601 Lind Avenue SW., Renton, Washington 98057-3356; telephone 
425-227-2195; facsimile 425-227-1320.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and 
opportunity for prior public comment on, these special conditions is 
impracticable because the substance of these special conditions has 
been subject to the public comment process in several prior instances 
with no substantive comments received. 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 March 29, 2012, Gulfstream Aerospace Corporation applied for a 
type certificate for their new Model GVII-G500 airplane. The Model 
GVII-G500 airplane will be a twin-engine, transport-category business 
jet capable of accommodating up to 19 passengers. The Model GVII-G500 
airplane will have a maximum takeoff weight of 76,850 lbs.

Type Certification Basis

    Under Title 14, Code of Federal Regulations (14 CFR) 21.17, 
Gulfstream must show that the Model GVII-G500 airplane meets the 
applicable provisions of 14 CFR part 25, as amended by Amendments 25-1 
through 25-129.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., part 25) do not contain adequate or appropriate 
safety standards for the Model GVII-G500 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 type certificate for that model be amended 
later to include any other model that incorporates the same or similar 
novel or unusual design feature, the special conditions would also 
apply to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, Model GVII-G500 airplanes 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 must issue a 
finding of regulatory adequacy under Sec.  611 of Public Law 92-574, 
the ``Noise Control Act of 1972.''

[[Page 27772]]

    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.  21.17(a)(2).

Novel or Unusual Design Feature

    The Model GVII-G500 airplane will incorporate the following novel 
or unusual design feature:
    Airbag systems on multiple-place and single-place side-facing 
seats.

Discussion

    Side facing seats are considered a novel design for transport-
category airplanes that include 14 CFR part 25, Amendment 25-64, in 
their certification bases, because this feature was not anticipated 
when those airworthiness standards were issued. Therefore, the existing 
regulations do not provide adequate or appropriate safety standards for 
occupants of side-facing seats. For the Model GVII-G500 airplane, FAA 
Special Conditions No. 25-618-SC, ``Technical Criteria for Approving 
Side-Facing Seats,'' proposed special conditions to address the 
certification of single- and multiple-place side-facing seats. Those 
proposed special conditions include condition 2(e), which requires the 
axial rotation of the upper leg (femur) to be limited to 35 degrees in 
either direction from the nominal seat position. To accommodate that 
requirement, Gulfstream has developed a new airbag system that will be 
installed close to the floor, and which is designed to limit the axial 
rotation of the occupant's upper legs.
    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 
Gulfstream Model GVII-G500 airplane. Should Gulfstream apply at a later 
date for a change to the type certificate to include another model 
incorporating 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 of airplane. It is not a rule of general applicability.
    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, 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 Gulfstream Aerospace Corporation Model 
GVII-G500 airplanes.
    In addition to the requirements of Sec. Sec.  25.562 and 25.785, 
and Special Conditions No. 25-495-SC, the following special conditions 
are part of the type certification basis for the Gulfstream Model GVII-
G500 airplane with leg-flail airbags installed on side-facing seats.
    1. For seats with a leg-flail airbag system, the system must deploy 
and provide protection under crash conditions where it is necessary to 
prevent serious injury. The means of protection must take into 
consideration a range of stature from a 2-year-old child to a 95th-
percentile male. At some buttock popliteal length and effective seat-
bottom depth, the lower legs will not be able to form a 90-degree angle 
relative to the upper leg; at this point, the lower leg flail would not 
occur. The leg-flail airbag system must provide a consistent approach 
to prevention of leg flail throughout that range of occupants whose 
lower legs can form a 90-degree angle relative to the upper legs when 
seated upright in the seat. Items that need to be considered include, 
but are not limited to, the range of occupants' popliteal height, the 
range of occupants' buttock popliteal length, the design of the seat 
effective height above the floor, and the effective depth of the seat-
bottom cushion.
    2. The leg-flail airbag system must provide adequate protection for 
each occupant regardless of the number of occupants of the seat 
assembly, considering that unoccupied seats may have an active leg-
flail airbag system.
    3. The leg-flail airbag system must not be susceptible to 
inadvertent deployment as a result of wear and tear, or inertial loads 
resulting from in-flight or ground maneuvers (including gusts and hard 
landings), and other operating and environmental conditions 
(vibrations, moisture, etc.) likely to occur in service.
    4. Deployment of the leg-flail airbag system must not introduce 
injury mechanisms to the seated occupant, nor result in injuries that 
could impede rapid egress.
    5. Inadvertent deployment of the leg-flail airbag system, during 
the most critical part of the flight, must either meet the requirement 
of Sec.  25.1309(b), or not cause a hazard to the airplane or its 
occupants.
    6. The leg-flail airbag system must not impede rapid egress of 
occupants from the airplane 10 seconds after airbag deployment.
    7. The leg-flail airbag system must be protected from lightning and 
high-intensity radiated fields (HIRF). The threats to the airplane 
specified in existing regulations regarding lightning (Sec.  25.1316) 
and HIRF (Sec.  25.1317) are incorporated by reference for the purpose 
of measuring lightning and HIRF protection.
    8. The leg-flail airbag system must function properly after loss of 
normal airplane electrical power, and after a transverse separation of 
the fuselage at the most critical location. A separation at the 
location of the leg-flail airbag system does not have to be considered.
    9. The leg-flail airbag system must not release hazardous 
quantities of gas or particulate matter into the cabin.
    10. The leg-flail airbag system installation must be protected from 
the effects of fire such that no hazard to occupants will result.
    11. A means must be available to verify the integrity of the leg-
flail airbag system's activation system prior to each flight, or the 
leg-flail airbag system's activation system must reliably operate 
between inspection intervals. The FAA considers that the loss of the 
leg-flail airbag system's deployment function alone (i.e., independent 
of the conditional event that requires the leg-flail airbag system's 
deployment) is a major-failure condition.
    12. The airbag inflatable material may not have an average burn 
rate of greater than 2.5 inches per minute when tested using the 
horizontal flammability test defined in part 25, appendix F, part I, 
paragraph (b)(5).

[[Page 27773]]

    13. The leg-flail airbag system, once deployed, must not adversely 
affect the emergency-lighting system (i.e., must not block floor-
proximity lights to the extent that the lights no longer meet their 
intended function).
