These special conditions are issued for the Bombardier Inc. Model BD-700-2A12 and BD-700-2A13 airplanes. These airplanes will have a digital-systems network architecture composed of several connected networks that may allow access to or by external computer systems and networks, and may result in airplane systems-security vulnerabilities. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.

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 
we receive.

Background

    On June 13, 2012, Bombardier Inc. applied for an amended type 
certificate for their new Model BD-700-2A12 and BD-700-2A13 airplanes. 
These airplanes are derivatives of the Model BD-700 series of 
airplanes, and are marketed as the Bombardier Global 7000 and Global 
8000, respectively. These airplanes are ultra-long-range, executive-
interior business jets.
    The Model BD-700-2A12 and BD-700-2A13 airplanes have a maximum 
certified passenger capacity of 19, and include new high-speed 
transonic wings with improved aerodynamic efficiency and a pressurized 
cabin for luxury interiors.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.101, Bombardier Inc. must show that the Model BD-700-2A12 and 
BD-700-2A13 airplanes meet the applicable provisions of part 25 as 
amended by Amendments 25-1 through 25-137.
    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 BD-700-2A12 and BD-700-2A13 
airplanes because of a novel or unusual design feature, special 
conditions are prescribed under the provisions of Sec.  21.16.

[[Page 23579]]

    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, these special conditions would also apply to 
the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the Model BD-700-2A12 and BD-700-2A13 airplanes 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 Model BD-700-2A12 and BD-700-2A13 airplanes will incorporate 
the following novel or unusual design feature: A digital-systems 
network architecture composed of several connected networks. This 
network architecture and network configuration will have the capability 
to allow access to or by external network sources, and may be used for 
or interfaced with a diverse set of functions, including:
     Flight-safety-related control, communication, and 
navigation systems (airplane-control domain);
     Operator business and administrative support (operator-
information domain); and
     Passenger information and entertainment systems 
(passenger-entertainment domain).

Discussion

    The Model BD-700-2A12 and BD-700-2A13 airplanes' digital-systems 
network architecture is novel or unusual for commercial transport 
airplanes as it allows connection to airplane electronic systems and 
networks, and access from sources external to the airplane (e.g., 
operator networks, wireless devices, Internet connectivity, service-
provider satellite communications, electronic flight bags, etc.) to the 
previously isolated airplane electronic assets. Airplane electronic 
assets include electronic equipment and systems, instruments, networks, 
servers, software and electronic components, field-loadable software 
and hardware applications, databases, etc. This proposed design may 
result in network security vulnerabilities from intentional or 
unintentional corruption of data and systems required for the safety, 
operation, and maintenance of the airplane.
    The existing regulations and guidance material did not anticipate 
these types of digital-system network architectures, nor access to 
airplane systems. Furthermore, 14 CFR part 25 regulations, and current 
system-safety assessment policy and techniques, do not address 
potential security vulnerabilities by unauthorized access to airplane 
data busses and servers. Therefore, these special conditions are issued 
to ensure that the security, integrity, and availability of airplane 
systems are not compromised by certain wired or wireless electronic 
connections between airplane data busses and networks.
    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.

Applicability

    As discussed above, these special conditions are applicable to the 
Model BD-700-2A12 and BD-700-2A13 airplanes. Should Bombardier Inc. 
apply at a later date for a change to the type certificate to include 
another model incorporating the same novel or unusual design feature, 
these special conditions would apply to that model as well.

Conclusion

    This action affects only a certain novel or unusual design feature 
on one model series of airplanes. 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, 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 electronic system-security protection 
from unauthorized external access on Bombardier Inc. Model BD-700-2A12 
and BD-700-2A13 airplanes.
    1. The applicant must ensure that the airplane electronic systems 
are protected 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 airplane is 
maintained, including all post-type-certification modifications that 
may have an impact on the approved electronic system-security 
safeguards.
