SUPPLEMENTARY INFORMATION:
SUMMARY:
Background
On March 29, 2005, Gulfstream
Aerospace Corporation (hereafter
referred to as ‘‘Gulfstream’’) applied for
an FAA type certificate for its new
Gulfstream Model GVI passenger
airplane. Gulfstream later applied for,
and was granted, an extension of time
for the type certificate, which changed
the effective application date to
September 28, 2006. The Gulfstream
Model GVI airplane will be an all-new,
two-engine jet transport airplane. The
maximum takeoff weight will be 99,600
pounds, with a maximum passenger
count of 19 passengers.
Type Certification Basis
Under provisions of Title 14, Code of
Federal Regulations (14 CFR) 21.17,
Gulfstream must show that the
Gulfstream Model GVI airplane
(hereafter referred to as ‘‘the GVI’’) meets
the applicable provisions of 14 CFR part
25, as amended by Amendments 25–1
through 25–119, 25–122, and 25–124. If
the Administrator finds that the
PO 00000
Frm 00003
Fmt 4700
Sfmt 4700
31453
applicable airworthiness regulations
(i.e., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for the GVI because of a novel or
unusual design feature, special
conditions are prescribed under the
provisions of § 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 novel or unusual
design features, the special conditions
would also apply to the other model
under provisions of § 21.101.
In addition to complying with the
applicable airworthiness regulations
and special conditions, the GVI 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 also issue a finding of
regulatory adequacy pursuant to section
611 of Public Law 92–574, the ‘‘Noise
Control Act of 1972.’’
The FAA issues special conditions, as
defined in 14 CFR 11.19, in accordance
with § 11.38, and they become part of
the type certification basis under
§ 21.17(a)(2).
Novel or Unusual Design Features
The Gulfstream model GVI airplane
will incorporate the following novel or
unusual design feature: A singleoccupant side-facing seat intended to be
occupied during takeoff and landing.
Discussion
Section 25.785(b), requires that ‘‘each
seat * * * at each station designated as
occupiable during takeoff and landing
must be designed so that a person
making proper use of these facilities
will not suffer serious injury in an
emergency landing as a result of the
inertia forces specified in §§ 25.561 and
25.562.’’ Additionally, § 25.562 requires
dynamic testing of all seats occupied
during takeoff and landing. The relative
forces and injury mechanisms affecting
the occupants of side-facing seats during
an emergency landing are different from
those of standard forward or aft facing
seats. Therefore, the FAA has
determined that, in addition to the
requirements of part 21 and part 25,
these special conditions are needed to
address this seat installation.
Discussion of Comments
Notice of proposed special conditions
No. 25–10–04–SC for Gulfstream GVI
airplanes was published in the Federal
Register on January 4, 2011 (76 FR 291).
No comments were received and these

Federal Register / Vol. 76, No. 105 / Wednesday, June 1, 2011 / Rules and Regulations
special conditions are adopted as
proposed.
Applicability
As discussed above, these special
conditions are applicable to the
Gulfstream model GVI 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 features, these
special conditions would apply to that
model as well.
Conclusion
This action affects only certain novel
or unusual design features of the GVI. It
is not a rule of general applicability.

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 GVI
airplanes.
In addition to the airworthiness
standards in §§ 25.562 and 25.785, the
following special conditions provide
injury criteria and installation/testing
guidelines that represent the minimum
acceptable airworthiness standard for
single-occupant side-facing seats:
A. The Injury Criteria
1. Existing Criteria: All injury
protection criteria of § 25.562(c)(1)
through (c)(6) apply to the occupant of
a side-facing seat. Head injury criterion
(HIC) assessments are only required for
head contact with the seat and/or
adjacent structures.
2. Body-to-Wall/Furnishing Contact:
The seat must be installed aft of a
structure such as an interior wall or
furnishing that will support the pelvis,
upper arm, chest, and head of an
occupant seated next to the structure. A
conservative representation of the
structure and its stiffness must be
included in the tests. It is
recommended, but not required, that the
contact surface of this structure be
covered with at least two inches of
energy absorbing protective padding
(foam or equivalent), such as Ensolite.
3. Thoracic Trauma: Thoracic trauma
index (TTI) injury criterion must be
substantiated by dynamic test or by
rational analysis based on previous
test(s) of a similar seat installation.
VerDate Mar<15>2010
17:41 May 31, 2011
Jkt 223001
Testing must be conducted with a side
impact dummy (SID), as defined by
Title 49, Code of Federal Regulations
(49 CFR) part 572, subpart F, or its
equivalent. TTI must be less than 85, as
defined in 49 CFR part 572, subpart F.
SID TTI data must be processed as
defined in Federal Motor Vehicle Safety
Standard (FMVSS) part 571.214, section
S6.13.5.
4. Pelvis: Pelvic lateral acceleration
must be shown by dynamic test or by
rational analysis based on previous
test(s) of a similar seat installation not
to exceed 130g. Pelvic acceleration data
must be processed as defined in FMVSS
part 571.214, section S6.13.5.
5. Shoulder Strap Loads: Where upper
torso straps (shoulder straps) are used
for occupants, tension loads in
individual straps must not exceed 1,750
pounds. If dual straps are used for
restraining the upper torso, the total
strap tension loads must not exceed
2,000 pounds.
B. General Test Guidelines
1. One longitudinal test with the SID
or its equivalent, undeformed floor, no
yaw, with all lateral structural supports
(armrests/walls).
Pass/fail injury assessments: TTI and
pelvic acceleration.
2. One longitudinal test with the
Hybrid II anthropomorphic test dummy
(ATD), deformed floor, yaw at 10
degrees, with all lateral structural
support (armrests/walls).
Pass/fail injury assessments: HIC; and
upper torso restrain load, restraint
system retention and pelvic
acceleration.
3. Vertical (14g) test with modified
Hybrid II ATDs using existing pass/fail
criteria.

SUPPLEMENTARY INFORMATION:
Background
On March 29, 2005, Gulfstream Aerospace Corporation (hereafter
referred to as ``Gulfstream'') applied for an FAA type certificate for
its new Gulfstream Model GVI passenger airplane. Gulfstream later
applied for, and was granted, an extension of time for the type
certificate, which changed the effective application date to September
28, 2006. The Gulfstream Model GVI airplane will be an all-new, two-
engine jet transport airplane. The maximum takeoff weight will be
99,600 pounds, with a maximum passenger count of 19 passengers.
Type Certification Basis
Under provisions of Title 14, Code of Federal Regulations (14 CFR)
21.17, Gulfstream must show that the Gulfstream Model GVI airplane
(hereafter referred to as ``the GVI'') meets the applicable provisions
of 14 CFR part 25, as amended by Amendments 25-1 through 25-119, 25-
122, and 25-124. 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 GVI 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 novel or
unusual design features, the special conditions would also apply to the
other model under provisions of Sec. 21.101.
In addition to complying with the applicable airworthiness
regulations and special conditions, the GVI 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 also issue a
finding of regulatory adequacy pursuant to section 611 of Public Law
92-574, the ``Noise Control Act of 1972.''
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 Features
The Gulfstream model GVI airplane will incorporate the following
novel or unusual design feature: A single-occupant side-facing seat
intended to be occupied during takeoff and landing.
Discussion
Section 25.785(b), requires that ``each seat * * * at each station
designated as occupiable during takeoff and landing must be designed so
that a person making proper use of these facilities will not suffer
serious injury in an emergency landing as a result of the inertia
forces specified in Sec. Sec. 25.561 and 25.562.'' Additionally, Sec.
25.562 requires dynamic testing of all seats occupied during takeoff
and landing. The relative forces and injury mechanisms affecting the
occupants of side-facing seats during an emergency landing are
different from those of standard forward or aft facing seats.
Therefore, the FAA has determined that, in addition to the requirements
of part 21 and part 25, these special conditions are needed to address
this seat installation.
Discussion of Comments
Notice of proposed special conditions No. 25-10-04-SC for
Gulfstream GVI airplanes was published in the Federal Register on
January 4, 2011 (76 FR 291). No comments were received and these
[[Page 31454]]
special conditions are adopted as proposed.
Applicability
As discussed above, these special conditions are applicable to the
Gulfstream model GVI 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 features, these special
conditions would apply to that model as well.
Conclusion
This action affects only certain novel or unusual design features
of the GVI. It is not a rule of general applicability.
