14 CFR Part 25
[Docket No. NM436; Special Conditions No. 25-421-SC]
Special Conditions: Boeing Model 747-8 Airplanes, Systems and
Data Networks Security--Isolation or Protection From Unauthorized
Passenger Domain Systems Access
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final special conditions.
-----------------------------------------------------------------------
SUMMARY: These special conditions are issued for Boeing Model 747-8
airplanes. This airplane will 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 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: April 18, 2011

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. The Model 747-8 is a
derivative of the 747-400. The Model 747-8 is a four-engine jet
transport airplane that will have a maximum takeoff weight of 970,000
pounds and new General Electric GEnx-2B67 engines. The Model 747-8 will
have two flight crew and the capacity to carry 605 passengers.
Type Certification Basis
Under the provisions of Title 14 Code of Federal Regulations (14
CFR) 21.101, Boeing must show that the Model 747-8 (hereafter referred
to as the 747-8) continues to meet the applicable provisions of 14 CFR
part 25, as amended by Amendments 25-1 through 25-117, except for
Sec. Sec. 25.809 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.
If the Administrator finds that the applicable airworthiness
regulations (i.e., part 25) do not contain adequate or appropriate
safety standards for the 747-8 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, the special conditions would also apply to the
other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the 747-8 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.
Novel or Unusual Design Features
The Boeing Model 747-8 airplane will incorporate the following
novel or unusual design features: Digital systems architecture composed
of several connected networks. The network architecture would be used
for 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 of Comments
Notice of proposed special conditions No. 25-10-01-SC for the
Boeing Model 747-8 airplane was published in the Federal Register on
December 9, 2010 (75 FR 76647). No comments were received and the
special conditions are adopted as proposed.
Applicability
As discussed above, these special conditions are applicable to
Boeing
[[Page 14795]]
Model 747-8 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, the special conditions would apply to
that model as well.
Conclusion
This action affects only certain novel or unusual design features
of the Boeing Model 747-8 airplane. It is not a rule of general
applicability.

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 the Boeing Model 747-8 airplane.
The design must prevent all inadvertent or malicious changes to,
and all adverse impacts upon, all systems, networks, hardware,
software, and data in the Aircraft Control Domain and in the Airline
Information Domain from all points within the Passenger Information
and Entertainment Domain.
