14 CFR Part 25
[Docket No. FAA-2012-0624; Special Conditions No. 25-464-SC]
Special Conditions: Gulfstream Aerospace LP (GALP), Model
Gulfstream G280 Airplane; Isolation or Aircraft Electronic System
Security Protection From Unauthorized Internal Access
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions; request for comments.
SUMMARY: These special conditions are issued for the Gulfstream
Aerospace LP, Model Gulfstream G280 airplane. This airplane will have
novel or unusual design features associated with connectivity of the
passenger service 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 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: The effective date of these special conditions is June 7, 2012.
We must receive your comments by August 13, 2012.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and
opportunity for prior public comment on, these special conditions are
impracticable because these procedures would significantly delay
issuance of the design approval and thus delivery of the affected
aircraft. In addition, the 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
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 will consider all comments we receive by the closing date for
comments. We may change these special conditions based on the comments
On March 30, 2006, Gulfstream Aerospace LP (hereafter referred to
as ``GALP'') applied for a type certificate for their new Model
Gulfstream G280 (hereafter referred to as ``Model G280'') airplane. The
Model G280 is a two-engine jet transport airplane with a maximum
takeoff weight of 39,600 pounds and an emergency exit arrangement to
support a maximum of 19 passengers. Although the Model G280 design
includes occupancy provisions for pilot and copilot only (no
passengers), GALP requested issuance of these special conditions to
support efficient design and certification of passenger cabin interiors
through the supplemental type certification process.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.17, GALP must show that the Model G280 meets the applicable
provisions of part 25, as amended by Amendments 25-1 through 25-120,
thereto, and Amendment 25-122. 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 Model G280 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, the special conditions would also apply to the
In addition to the applicable airworthiness regulations and special
conditions, the Model G280 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; and the FAA must issue a finding of
regulatory adequacy under Sec. 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 Model G280 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 functions);
2. Airline business and administrative support (airline information
3. Passenger information and entertainment systems (passenger
The Model G280 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 GALP airplane models. This may
allow the exploitation of network security vulnerabilities and
increased 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 are being 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 between airplane systems and the passenger entertainment
As discussed above, these special conditions are applicable to the
Model G280. Should GALP apply at a later date for a change to the type
certificate to include another model incorporating the same novel or
unusual design feature, the special conditions would apply to that
model as well.
This action affects only certain novel or unusual design features
on one model of airplane. It is not a rule of general applicability.
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

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 Aerospace LP, Model
Gulfstream G280 airplanes.
1. Isolation or Aircraft Electronic System Security Protection from
Unauthorized Internal Access. 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 aircraft is
maintained, including all post type certification modifications that
may have an impact on the approved electronic system security
