Background On March 17th, 2022, L2 Consulting Services, Inc., applied for a supplemental type certificate for the installation of a digital system that contains a wireless and hardwired network with hosted application functionality that allows access, from sources internal to the airplane, to the airplane’s internal electronic components. The Bombardier Model CL–600–2B16 (604 variant) airplane is a twin-engine business jet with a maximum takeoff weight of 47,600 pounds (21,591 Kg) and a maximum PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 seating capacity of twenty passengers and two crew members. Type Certification Basis Under the provisions of title 14, Code of Federal Regulations (14 CFR), § 21.101, L2 Consulting Services Inc., must show that the Bombardier Model CL–600–2B16 (604 variant) airplane, as changed, continues to meet the applicable provisions of the regulations listed in Type Certificate No. A21EA, 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 Bombardier Model CL–600–2B16 (604 variant) airplane, because of a novel or unusual design feature, special conditions are prescribed under the provisions of § 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 § 21.101. In addition to the applicable airworthiness regulations and special conditions, the Bombardier Model CL– 600–2B16 (604 variant) airplane must comply with the fuel-vent and exhaustemission 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 § 11.38, and they become part of the type certification basis under § 21.101. Novel or Unusual Design Feature The Bombardier Model CL–600–2B16 (604 variant) airplane will incorporate the following novel or unusual design feature, which is the installation of a digital system that contains a wireless and hardwired network with hosted application functionality that allows access, from sources internal to the airplane, to the airplane’s internal electronic components. Discussion The Bombardier Model CL–600–2B16 (604 variant) airplane electronic system architecture and network configuration change is novel or unusual for commercial transport airplanes because it is composed of several connected wireless and hardwired networks. This proposed system and network E:\FR\FM\21SER1.SGM 21SER1 Federal Register / Vol. 87, No. 182 / Wednesday, September 21, 2022 / Rules and Regulations khammond on DSKJM1Z7X2PROD with RULES architecture is used for a diverse set of airplane functions, including: • flight-safety related control and navigation systems, • airline business and administrative support, and • passenger entertainment. The airplane’s 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 airplanesystem 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 hardwired 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 Bombardier Model CL–600–2B16 (604 variant) airplane. Should L2 Consulting Services, Inc., apply at a later date for a supplemental type certificate to modify any other model included on Type Certificate No. A21EA to incorporate the same novel or unusual design feature, these special conditions would apply to that model as well. VerDate Sep<11>2014 16:33 Sep 20, 2022 Jkt 256001 57573 Conclusion DEPARTMENT OF TRANSPORTATION This action affects only a certain novel or unusual design feature on the Bombardier Model CL–600–2B16 (604 variant) airplane. It is not a rule of general applicability and affects only the applicant who applied to the FAA for approval of this feature on the airplane.

Background

    On March 17th, 2022, L2 Consulting Services, Inc., applied for a 
supplemental type certificate for the installation of a digital system 
that contains a wireless and hardwired network with hosted application 
functionality that allows access, from sources internal to the 
airplane, to the airplane's internal electronic components. The 
Bombardier Model CL-600-2B16 (604 variant) airplane is a twin-engine 
business jet with a maximum takeoff weight of 47,600 pounds (21,591 Kg) 
and a maximum seating capacity of twenty passengers and two crew 
members.

Type Certification Basis

    Under the provisions of title 14, Code of Federal Regulations (14 
CFR), Sec.  21.101, L2 Consulting Services Inc., must show that the 
Bombardier Model CL-600-2B16 (604 variant) airplane, as changed, 
continues to meet the applicable provisions of the regulations listed 
in Type Certificate No. A21EA, 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 Bombardier Model CL-600-2B16 (604 
variant) airplane, 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 Bombardier Model CL-600-2B16 (604 variant) airplane 
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 Bombardier Model CL-600-2B16 (604 variant) airplane will 
incorporate the following novel or unusual design feature, which is the 
installation of a digital system that contains a wireless and hardwired 
network with hosted application functionality that allows access, from 
sources internal to the airplane, to the airplane's internal electronic 
components.

Discussion

    The Bombardier Model CL-600-2B16 (604 variant) airplane electronic 
system architecture and network configuration change is novel or 
unusual for commercial transport airplanes because it is composed of 
several connected wireless and hardwired networks. This proposed system 
and network

[[Page 57573]]

architecture is used for a diverse set of airplane functions, 
including:
     flight-safety related control and navigation systems,
     airline business and administrative support, and
     passenger entertainment.
    The airplane's 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 hardwired 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 
Bombardier Model CL-600-2B16 (604 variant) airplane. Should L2 
Consulting Services, Inc., apply at a later date for a supplemental 
type certificate to modify any other model included on Type Certificate 
No. A21EA 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 the Bombardier Model CL-600-2B16 (604 variant) airplane. It is not a 
rule of general applicability and affects only the applicant who 
applied to the FAA for approval of this feature on the airplane.
