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 issuance.

Background
On April 21, 2011, Gulfstream
Aerospace Corporation (hereafter
referred to as ‘‘Gulfstream’’) applied for
a supplemental type certificate to install
a new interior design configuration in
the Gulfstream Model GIV–X passenger
airplane. The Gulfstream Model GIV–X
is a two-engine jet transport airplane
with a maximum takeoff weight of
47,600 pounds and an interior
configuration for a maximum of 19
passengers.
Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.101,
Gulfstream must show that the
Gulfstream Model GIV–X airplane
(hereafter referred to as the ‘‘GIV–X’’), as
changed, continues to meet the
applicable provisions of the regulations
incorporated by reference in Type
Certificate No. A12EA or the applicable
regulations in effect on the date of
application for the change. The
regulations incorporated by reference in
the type certificate are commonly
referred to as the ‘‘original type
certification basis.’’ The regulations
incorporated by reference in Type
Certificate No. A12EA are as follows:
14 CFR part 25, effective February 1,
1965, including Amendments 25–1
through 25–56, except for the following
sections which are limited to showing
compliance with the amendments
indicated: Part 25 effective February 1,
1965, §§ 25.109, 25.571, and 25.813;
part 25 Amendment 25–22, § 25.571;
and part 25 Amendment 25–15,
§ 25.807(c)(2). In addition, the
certification basis includes certain
special conditions, exemptions, and
equivalent safety findings 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 GIV–X 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 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,
the special conditions would also apply
to the other model.
In addition to the applicable
airworthiness regulations and special
VerDate Mar<15>2010
14:45 Oct 19, 2011
Jkt 226001
conditions, the GIV–X 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 § 11.38, and they become part of
the type certification basis under
§ 21.101.
Novel or Unusual Design Features
The GIV–X will incorporate the
following novel or unusual design
features: digital systems architecture
composed of several connected
networks. The proposed architecture
and network configuration may be used
for, or interfaced with, a diverse set of
functions, including:
1. Flight-safety related control,
communication, and navigation systems
(aircraft control domain);
2. Airline business and administrative
support (airline information domain);
3. Passenger information and
entertainment systems (passenger
entertainment domain), and;
4. The capability to allow access to or
by external sources.
Discussion
The GIV–X architecture and network
configuration may allow increased
connectivity to, and access by, external
airplane sources, airline operations, and
maintenance systems to the aircraft
control domain and airline information
domain. The aircraft control domain
and airline information domain perform
functions required for the safe operation
and maintenance of the airplane.
Previously these domains had very
limited connectivity with external
sources. The architecture and network
configuration may allow the
exploitation of network security
vulnerabilities resulting in intentional
or unintentional destruction, disruption,
degradation, or exploitation of data,
systems, and networks critical to the
safety and maintenance of the airplane.
The existing regulations and guidance
material did not anticipate these types
of airplane system architectures.
Furthermore, 14 CFR regulations and
current system safety assessment policy
and techniques do not address potential
security vulnerabilities, which could be
exploited by unauthorized access to
airplane systems, data buses, and
servers. Therefore, these special
conditions are issued to ensure that the
security (i.e., confidentiality, integrity,
and availability) of airplane systems is
not compromised by unauthorized
wired or wireless electronic
connections.

Applicability
As discussed above, these special
conditions are applicable to the
Gulfstream Model GIV–X. Should
Gulfstream apply at a later date for a
supplemental type certificate to modify
any other model included on the Type
Certificate No. A12EA to incorporate 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 on one model
of airplane. 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 issuance. 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.

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 Model
GIV–X airplanes.
1. The applicant must ensure airplane
electronic system security protection
from access by unauthorized sources
external to the airplane, including those
possibly caused by maintenance
activity.
2. The applicant must ensure that
electronic system security threats are
identified and assessed, and that
effective electronic system security
protection strategies are implemented to

protect the airplane from all adverse
impacts on safety, functionality, and
continued airworthiness.
3. The applicant must establish
appropriate procedures to allow the
operator to ensure that continued
airworthiness of the aircraft is
maintained, including all post Type
Certification modifications that may
have an impact on the approved
electronic system security safeguards.

Background
On April 21, 2011, Gulfstream Aerospace Corporation (hereafter
referred to as ``Gulfstream'') applied for a supplemental type
certificate to install a new interior design configuration in the
Gulfstream Model GIV-X passenger airplane. The Gulfstream Model GIV-X
is a two-engine jet transport airplane with a maximum takeoff weight of
47,600 pounds and an interior configuration for a maximum of 19
passengers.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, Gulfstream must show that the Gulfstream Model GIV-X
airplane (hereafter referred to as the ``GIV-X''), as changed,
continues to meet the applicable provisions of the regulations
incorporated by reference in Type Certificate No. A12EA or the
applicable regulations in effect on the date of application for the
change. The regulations incorporated by reference in the type
certificate are commonly referred to as the ``original type
certification basis.'' The regulations incorporated by reference in
Type Certificate No. A12EA are as follows:
14 CFR part 25, effective February 1, 1965, including Amendments
25-1 through 25-56, except for the following sections which are limited
to showing compliance with the amendments indicated: Part 25 effective
February 1, 1965, Sec. Sec. 25.109, 25.571, and 25.813; part 25
Amendment 25-22, Sec. 25.571; and part 25 Amendment 25-15, Sec.
25.807(c)(2). In addition, the certification basis includes certain
special conditions, exemptions, and equivalent safety findings 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 GIV-X 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,
the special conditions would also apply to the other model.
In addition to the applicable airworthiness regulations and special
conditions, the GIV-X 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 GIV-X will incorporate the following novel or unusual design
features: digital systems architecture composed of several connected
networks. The proposed architecture and network configuration may be
used for, or interfaced with, a diverse set of functions, including:
1. Flight-safety related control, communication, and navigation
systems (aircraft control domain);
2. Airline business and administrative support (airline information
domain);
3. Passenger information and entertainment systems (passenger
entertainment domain), and;
4. The capability to allow access to or by external sources.
Discussion
The GIV-X architecture and network configuration may allow
increased connectivity to, and access by, external airplane sources,
airline operations, and maintenance systems to the aircraft control
domain and airline information domain. The aircraft control domain and
airline information domain perform functions required for the safe
operation and maintenance of the airplane. Previously these domains had
very limited connectivity with external sources. The architecture and
network configuration may allow the exploitation of network security
vulnerabilities resulting in intentional or unintentional destruction,
disruption, degradation, or exploitation of data, systems, and networks
critical to the safety and maintenance of the airplane. The existing
regulations and guidance material did not anticipate these types of
airplane system architectures. Furthermore, 14 CFR regulations and
current system safety assessment policy and techniques do not address
potential security vulnerabilities, which could be exploited by
unauthorized access to airplane systems, data buses, and servers.
Therefore, these special conditions are issued to ensure that the
security (i.e., confidentiality, integrity, and availability) of
airplane systems is not compromised by unauthorized wired or wireless
electronic connections.
Applicability
As discussed above, these special conditions are applicable to the
Gulfstream Model GIV-X. Should Gulfstream apply at a later date for a
supplemental type certificate to modify any other model included on the
Type Certificate No. A12EA to incorporate 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
on one model of airplane. 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 issuance. 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 Model GIV-X airplanes.
1. The applicant must ensure airplane electronic system security
protection from access by unauthorized sources external to the
airplane, including those possibly caused by maintenance activity.
2. The applicant must ensure that electronic system security
threats are identified and assessed, and that effective electronic
system security protection strategies are implemented to
[[Page 65105]]
protect the airplane from all adverse impacts on safety, functionality,
and continued airworthiness.
3. The applicant must establish appropriate procedures to allow the
operator to ensure that continued airworthiness of the aircraft is
maintained, including all post Type Certification modifications that
may have an impact on the approved electronic system security
safeguards.
