200/-200LR/-300/-300ER Series Airplanes; 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 Boeing Model No. 
777-200/-200LR/-300/-300ER series airplanes. These airplanes, as 
modified by Archeion Holdings, LLC (Archeion), will have a novel or 
unusual design feature when compared to the state of technology 
envisioned in the airworthiness standards for transport category 
airplanes. This design feature is a digital systems architecture for 
the installation of a system with wireless network and hosted 
application functionality that allows access, from sources internal to 
the airplane, to the airplane's internal electronic components. 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.

has been published in the Federal Register for public comment in 
several prior instances with no substantive comments received. 
Therefore, the FAA finds, pursuant to 14 CFR 11.38(b), that new 
comments are unlikely and prior public notice and comment are 
unnecessary.

Comments Invited

    The FAA invites 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.
    The FAA will consider all comments received by the closing date for 
comments. The FAA may change these special conditions based on the 
comments received.

Background

    On July 14, 2020, Archeion applied for a change to Type Certificate 
No.

[[Page 37016]]

T00001SE for the installation of an Avionica avWIFI system with 
wireless network and hosted application functionality in Boeing Model 
777-200/-200LR/-300/-300ER series airplanes. These airplanes, currently 
approved under Type Certificate No. T00001SE, are twin-engine, 
transport category airplanes, with a maximum takeoff weight between 
535,000 lbs and 775,000 lbs pounds, and a maximum passenger capacity of 
550 persons.

Type Certification Basis

    Under the provisions of title 14, Code of Federal Regulations (14 
CFR) 21.101, Archeion must show that the Boeing Model 777-200/-200LR/-
300/-300ER series airplanes, as changed, continue to meet the 
applicable provisions of the regulations listed in Type Certificate No. 
T00001SE or the applicable regulations in effect on the date of 
application for the change, except for earlier amendments as agreed 
upon by the FAA.
    If the Administrator finds that the applicable airworthiness 
regulations (e.g., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for the Boeing Model 777-200/-200LR/-300/-
300ER series airplanes 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 applicant apply for a supplemental type 
certificate to modify any other model included on the same type 
certificate 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 Boeing Model 777-200/-200LR/-300/-300ER series 
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 Feature

    The Boeing Model 777-200/-200LR/-300/-300ER series airplanes will 
incorporate the following novel or unusual design feature:
    A digital systems architecture for the installation of a system 
with wireless network and hosted application functionality that allows 
access, from sources internal to the airplane, to the airplane's 
internal electronic components.

Discussion

    The digital systems architecture for the installation of an 
Avionica avWIFI system with wireless network and hosted application 
functionality on these Boeing Model 777 airplanes is a novel or unusual 
design feature for transport category airplanes because it is composed 
of several connected networks. This proposed network architecture is 
used for a diverse set of airplane functions, including:
    <bullet> Flight-safety related control and navigation systems,
    <bullet> airline business and administrative support, and
    <bullet> passenger entertainment.
    The airplane control domain and airline information-services domain 
of these networks perform functions required for the safe operation and 
maintenance of the airplane. Previously, these domains had very limited 
connectivity with other network sources. This network architecture 
creates a potential for unauthorized persons to access the aircraft 
control domain and airline information-services domain from sources 
internal to the airplane, and presents security vulnerabilities related 
to the introduction of computer viruses and worms, user errors, and 
intentional sabotage of airplane electronic assets (networks, systems, 
and databases) critical to the safety and maintenance of the airplane.
    The existing FAA regulations did not anticipate these networked 
airplane system architectures. Furthermore, these regulations and the 
current guidance material do not address potential security 
vulnerabilities, which could be exploited by unauthorized access to 
airplane networks, data buses, and servers. Therefore, these special 
conditions ensure that the security (i.e., confidentiality, integrity, 
and availability) of airplane systems will not be compromised by 
unauthorized wired or wireless electronic connections from within the 
airplane. These special conditions also require the applicant to 
provide appropriate instructions to the operator to maintain all 
electronic-system safeguards that have been implemented as part of the 
original network design so that this feature does not allow or 
reintroduce security threats.
    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 
Boeing Model 777-200/-200LR/-300/-300ER series airplanes. Should 
Archeion apply at a later date for a supplemental type certificate to 
modify any other model included on Type Certificate No. T00001SE to 
incorporate 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 Boeing Model 777-200/-200LR/-300/-300ER series airplanes. It is not 
a rule of general applicability and affects only the applicant.

airplane electronic-system security protection from unauthorized 
internal access.
    (a) 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.
    (b) 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 
safeguards.
