Abstract
These special conditions are issued for the Gulfstream Aerospace Corporation (Gulfstream) Model GVIII-G700 and GVIII-G800 series airplanes. These airplanes will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is a side-stick controller for one-hand operation requiring wrist motion only, not arms. 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.

SUPPLEMENTARY INFORMATION: The substance of these special conditions
has been published in the Federal Register for public comment in
several prior instances with no substantive comments received.
Therefore, the FAA finds, pursuant to title 14, Code of Federal
Regulations (14 CFR) 11.38(b), that new comments are unlikely, and
notice and comment prior to this publication are unnecessary.
Privacy
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in title 14
CFR 11.35, the FAA will post all comments received without change to
<a href="http://www.regulations.gov">www.regulations.gov</a>, including any personal information you provide.
The FAA will also post a report summarizing each substantive verbal
contact received about these special conditions.
Confidential Business Information
Confidential Business Information (CBI) is commercial or financial
information that is both customarily and actually treated as private by
its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552),
CBI is exempt from public disclosure. If your comments responsive to
these special conditions contain commercial or financial information
that is customarily treated as private, that you actually treat as
private, and that is relevant or responsive to these special
conditions, it is important that you clearly designate the submitted
comments as CBI. Please mark each page of your submission containing
CBI as ``PROPIN.'' The FAA will treat such marked submissions as
confidential under the FOIA, and the indicated comments will not be
placed in the public docket of these special conditions. Send
submissions containing CBI to Todd Martin, Airframe Section, AIR-622,
Technical Policy Branch, Aircraft Certification Service, Federal
Aviation Administration, 2200 South 216th Street, Des Moines,
Washington 98198;

specifically designated as CBI, will be placed in the public docket for
these special conditions.
Comments Invited
The FAA invites 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.
The FAA will consider all comments received by the closing date for
comments and will consider comments filed late if it is possible to do
so without incurring delay. The FAA may change these special conditions
based on the comments received.
Background
On December 31, 2019, Gulfstream applied for an amendment to Type
Certificate No. T00015AT to include the new Model GVIII-G700 and GVIII-
G800 series airplanes. These airplanes, which are derivatives of the
Model GVI currently approved under Type Certificate No. T00015AT, are
twin-engine, transport-category airplanes, with maximum seating for 19
passengers, and a maximum take-off weight of 107,600 pounds (GVIII-
G700) and 105,600 pounds (GVIII-G800).
Type Certification Basis
Under the provisions of 14 CFR 21.101, Gulfstream must show that
the Model GVIII-G700 and GVIII-G800 series airplanes meet the
applicable provisions of the regulations listed in Type Certificate No.
T00015AT, or the applicable regulations in effect on the date of
application for the change, except for earlier amendments as agreed
upon by the FAA.
If the Administrator finds that the applicable airworthiness
regulations (e.g., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Gulfstream Model GVIII-G700 and
GVIII-G800 series airplanes 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 feature, or should any other model already included on
the same type certificate be modified 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 Gulfstream Model GVIII-G700 and GVIII-G800 series
airplanes must comply with the 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 14 CFR 11.38, and they become part of the type
certification basis under Sec. 21.101.
Novel or Unusual Design Feature
The Gulfstream Model GVIII-G700 and GVIII-G800 series airplanes
will incorporate the following novel or unusual design feature:
A side-stick controller for one-hand operation requiring wrist
motion only, not arms.
Discussion
The Gulfstream Model GVIII-700 and GVIII-800 series airplanes are
equipped with side-stick controllers instead of conventional wheel or
control stick controllers. Side-stick controllers are designed to be
operated using only one hand. The requirements of Sec. 25.397(c),
which define limit pilot forces and torques for conventional wheel or
stick controllers, are not adequate for side-stick controllers because
pilot forces are applied to side-stick controllers with only the wrist,
not arms. Special conditions are necessary to specify the appropriate
loading conditions for side-stick controllers.
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 GVIII-G700 and GVIII-G800 series airplanes. Should
Gulfstream apply at a later date for a change to the type certificate
to include another model that incorporates the same novel or unusual
design feature, or should any other model already included on the same
type certificate be modified to incorporate the same novel or unusual
design feature, these special conditions would apply to that model as
well.
Conclusion
This action affects only a certain novel or unusual design feature
on Gulfstream Model GVIII-G700 and GVIII-G800 series airplanes. It is
not a rule of general applicability.

The Special Conditions
[ssquf] Accordingly, pursuant to the authority delegated to me by
the Administrator, the following special conditions are issued, in lieu
of the aileron-control and elevator-control forces specified in Sec.
25.397(c), as part of the type certification basis for Gulfstream
Aerospace Corporation Model GVIII-G700 and GVIII-G800 series airplanes.
For Gulfstream Aerospace Corporation Model GVIII-G700 and GVIII-
G800 series airplanes equipped with side-stick controls designed for
forces to be applied by one wrist and not arms, the limit pilot forces
are as follows.
(a) For all components between and including the side-stick
control-assembly handle and its control stops:
------------------------------------------------------------------------
Pitch Roll
------------------------------------------------------------------------
Nose up, 200 lbs force.................... Nose left, 100 lbs force.
Nose down, 200 lbs force.................. Nose right, 100 lbs force.
------------------------------------------------------------------------
(b) For all other components of the side-stick control assembly,
but excluding the internal components of the electrical sensor
assemblies, to avoid damage to the control system as the result of an
in-flight jam:
------------------------------------------------------------------------
Pitch Roll
------------------------------------------------------------------------
Nose up, 125 lbs force.................... Nose left, 50 lbs force.
Nose down, 125 lbs force.................. Nose right, 50 lbs force.
