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 associated with the installation of a digital system that contains a wireless and hardwired network with hosted application functionality that allows access, from sources internal to the airplane, to the airplane's internal electronic components. 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.

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 the individual listed in the FOR FURTHER
INFORMATION CONTACT section above. Comments the FAA receives, which are
not 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 a 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 title 14, Code of Federal Regulations (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
[[Page 3335]]
with Sec. 11.38, and they become part of the type certification basis
under Sec. 21.101.
Novel or Unusual Design Features
The Gulfstream Model GVIII-G700 and GVIII-G800 series airplanes
will incorporate the following novel or unusual design feature:
The installation of a digital system that contains a wireless and
hardwired network with hosted application functionality that allows
access, from sources internal to the airplane, to the airplane's
internal electronic components.
Discussion
The Gulfstream Model GVIII-G700 and GVIII-G800 series airplanes
electronic system architecture and network configuration change are
novel or unusual for commercial transport airplanes because they are
composed of several connected wireless and hardwired networks. This
proposed system and network architecture are used for a diverse set of
airplane functions, including:
<bullet> Flight-safety related control and navigation systems,
<bullet> Airline business and administrative support, and
<bullet> Passenger entertainment.
The airplanes' control domains and airline information services
domain of these networks perform functions required for the safe
operation and maintenance of the airplane. Previously, these domains
had very limited connectivity with other network sources. This network
architecture creates a potential for unauthorized persons to access the
airplanes' control domain from sources internal to the airplane and
presents security vulnerabilities related to the introduction of
computer viruses and worms, user errors, and intentional sabotage of
airplane electronic assets (networks, systems, and databases) critical
to the safety and maintenance of the airplane.
The existing FAA regulations did not anticipate these networked
airplane-system architectures. Furthermore, these regulations and the
current guidance material do not address potential security
vulnerabilities, which could be exploited by unauthorized access to
airplane networks, data buses, and servers. Therefore, these special
conditions ensure that the security (i.e., confidentiality, integrity,
and availability) of airplane systems will not be compromised by
unauthorized wireless or hardwired electronic connections from within
the airplane. These special conditions also require the applicant to
provide appropriate instruction to the operator to maintain all
electronic-system safeguards that have been implemented as part of the
original network design so that this feature does not allow or
reintroduce security threats.
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 the other model
as well.
Conclusion
This action affects only a certain novel or unusual design feature
on one model on Gulfstream Model GVIII-G700 and GVIII-G800 series of
airplanes. 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 Model GVIII-G700 and GVIII-
G800 series airplanes for airplane electronic-system internal access:
1. The applicant must ensure that the design provides isolation
from, or airplane electronic-system security protection against, access
by unauthorized sources internal to the airplane. The design must
prevent inadvertent and malicious changes to, and all adverse impacts
upon, airplane equipment, systems, networks, or other assets required
for safe flight and operations.
2. The applicant must establish appropriate procedures to allow the
operator to ensure that continued airworthiness of the airplane is
maintained, including all post-type certification modifications that
may have an impact on the approved electronic-system security
safeguards.
