14 CFR Part 25
[Docket No. NM413; Special Conditions No. 25-401-SC]
Special Conditions: Boeing Model 747-8/-8F Airplanes, Systems and
Data Networks Security--Protection of Airplane Systems and Data
Networks From Unauthorized External Access
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for the Boeing Model 747-
8/-8F airplane. This airplane will have novel or unusual design
features associated with the architecture and connectivity capabilities
of the airplane's computer systems and networks, which may allow access
to external computer systems and networks. Connectivity to external
systems and networks may result in security vulnerabilities to the
airplane's systems. 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: Effective Date: February 16, 2010.

SUPPLEMENTARY INFORMATION:
Background
On November 4, 2005, The Boeing Company, P.O. Box 3707, Seattle, WA
98124, applied for an amendment to Type Certificate Number A20WE to
include the new Model 747-8 passenger airplane and the new Model 747-8F
freighter airplane. The Model 747-8 and the Model 747-8F are
derivatives of the 747-400 and the 747-400F, respectively. Both the
Model 747-8 and the Model 747-8F are four-engine jet transport
airplanes that will have a maximum takeoff weight of 975,000 pounds and
new General Electric GEnx-2B67 engines. The Model 747-8 will have two
flight crew and the capacity to carry 660 passengers. The Model 747-8F
will have two flight crew and a zero passenger capacity, although the
FAA has issued a partial grant of exemption to Boeing for the carriage
of up to six supernumeraries for the 747-8F.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.17, Boeing must show that the Model 747-8 and 747-8F (hereafter
referred as 747-8/-8F) meet the applicable provisions of part 25, as
amended by Amendments 25-1 through 25-120, except for Sec. Sec.
25.809(a) and 25.812, which will remain at Amendment 25-115. These
regulations will be incorporated into Type Certificate No. A20WE after
type certification approval of the 747-8/-8F.
In addition, the certification basis includes other regulations,
special conditions and exemptions 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 747-8/-8F because of a novel or
unusual design feature, special conditions are prescribed under the
provisions of Sec. 21.16.
In addition to the applicable airworthiness regulations and special
conditions, the 747-8/-8F 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.
Special conditions, as defined in Sec. 11.19, are issued under
Sec. 11.38, and become part of the type certification basis under
Sec. 21.101.
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 or similar
novel or unusual design feature, or should any other model already
included on the same type certificate be modified to incorporate the
same or similar novel or unusual design feature, the special conditions
would also apply to the other model under Sec. 21.101.
Novel or Unusual Design Features
The Boeing Model 747-8/-8F airplane will incorporate the following
novel or unusual design features: digital systems architecture composed
of several connected networks. The 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 network
sources.
Discussion
The Model 747-8/-8F architecture and network configuration may
allow increased connectivity to and access from external network
sources and airline operations and maintenance networks 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 network 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
[[Page 2434]]
airplane networks, data bases, and servers. Therefore, these special
conditions and a means of compliance are provided to ensure that the
security (i.e., confidentiality, integrity, and availability) of
airplane systems is not compromised by unauthorized wired or wireless
electronic connections.
Discussion of Comments
Notice of proposed special conditions No. 25-09-09-SC for the
Boeing Model 747-8/-8F airplanes was published in the Federal Register
on October 2, 2009 (74 FR 50926). No comments were received.
Applicability
As discussed above, these special conditions are applicable to
Boeing Model 747-8/-8F airplanes. Should Boeing 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 special
conditions would apply to that model as well under the provisions of
Sec. 21.101.
Conclusion
This action affects only certain novel or unusual design features
of the Boeing Model 747-8/-8F airplane. It is not a rule of general
applicability.
