DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 25
[Docket No. NM447 Special Conditions No. 25-11-06-SC]
Special Conditions: Gulfstream Model GVI Airplane; Electronic
Systems Security Isolation or Protection From Unauthorized Passenger
Systems Access
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed special conditions.
-----------------------------------------------------------------------
SUMMARY: This action proposes special conditions for the Gulfstream GVI
airplane. This airplane may have novel or unusual design features
associated with connectivity of the passenger domain computer systems
to the airplane critical systems and data networks. The applicable
airworthiness regulations do not contain adequate or appropriate safety
standards for these design features. These proposed 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.
DATES: We must receive your comments by April 11, 2011.
ADDRESSES: You must mail two copies of your comments to: Federal
Aviation Administration, Transport Airplane Directorate, Attn: Rules
Docket (ANM-113), Docket No. NM447, 1601 Lind Avenue, SW., Renton,
Washington 98057-3356. You may deliver two copies to the Transport
Airplane Directorate at the above address. You must mark your comments:
Docket No. NM447. You can inspect comments in the Rules Docket
weekdays, except Federal holidays, between 7:30 a.m. and 4 p.m.
FOR FURTHER INFORMATION CONTACT: Will Struck, FAA, Airplane and Flight
Crew Interface Branch, ANM-111, Transport Standards Staff, Transport
Airplane Directorate, Aircraft Certification Service, 1601 Lind Avenue,

SUPPLEMENTARY INFORMATION:
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 ask
that you send us two copies of written comments.
We will file in the docket all comments we receive, as well as a
report summarizing each substantive public contact with FAA personnel
concerning these special conditions. You can inspect the docket before
and after the comment closing date. If you wish to review the docket in
person, go to the address in the ADDRESSES section of this preamble
between 7:30 a.m. and 4 p.m., Monday through Friday, except Federal
holidays.
We will consider all comments we receive on or before the closing
date for comments. We will consider comments filed late if it is
possible to do so without incurring expense or delay. We may change
these special conditions based on the comments we receive.
If you want us to acknowledge receipt of your comments on this
proposal, include with your comments a self-addressed, stamped postcard
on which you have written the docket number. We will stamp the date on
the postcard and mail it back to you.
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 with an executive cabin interior. 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.
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).
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.
Novel or Unusual Design Features
The GVI 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 of Proposed Special Conditions
The proposed Model GVI integrated network configuration may allow
increased connectivity with external network sources and will have more
interconnected networks and systems, such as passenger entertainment
and information services, than previous Gulfstream airplane models.
This may allow the exploitation of network security vulnerabilities and
increase
[[Page 10529]]
risks potentially resulting in unsafe conditions for the airplane and
its occupants.
This potential exploitation of security vulnerabilities may result
in intentional or unintentional destruction, disruption, degradation,
or exploitation of data and systems critical to the safety and
maintenance of the airplane. The existing regulations and guidance
material did not anticipate these types of 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 networks
and servers. Therefore, these special conditions and a means of
compliance are proposed to ensure that the security (i.e.,
confidentiality, integrity, and availability) of airplane systems is
not compromised by unauthorized wired or wireless electronic
connections between airplane systems and networks and the passenger
entertainment domain.
Applicability
As discussed above, these proposed special conditions are
applicable to the GVI. 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 proposed 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.
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 Proposed Special Conditions
Accordingly, the Federal Aviation Administration (FAA) proposes the
following special condition as part of the type certification basis for
the GVI airplanes.
The design must isolate or provide protection from any inadvertent
or malicious change to, and any adverse effect on any systems,
software, or data in the aircraft control domain or airline information
domain from any point within the passenger entertainment domain.
