Background On October 1, 2021, L2 Consulting Services, Inc., applied for a supplemental type certificate for the installation of a digital system that E:\FR\FM\06SER1.SGM 06SER1 54352 Federal Register / Vol. 87, No. 171 / Tuesday, September 6, 2022 / Rules and Regulations 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 BD–700–1A10 and BD–700–1A11 airplanes are twin-engine business jets with a maximum takeoff weight of 93,500 pounds (42,410 Kg) and a maximum seating capacity of seventeen passengers and two crew members. jspears on DSK121TN23PROD with RULES 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 BD–700– 1A10 and BD–700–1A11 airplanes, as changed, continue to meet the applicable provisions of the regulations listed in Type Certificate No. T00003NY, 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., 14CFR part25) do not contain adequate or appropriate safety standards for the Bombardier Model BD–700– 1A10 and BD–700–1A11 airplanes, 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 BD– 700–1A10 and BD–700–1A11 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 § 11.38, and they become part of the type certification basis under § 21.101. Novel or Unusual Design Feature The Bombardier Model BD–700–1A10 and BD–700–1A11 airplanes 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 VerDate Sep<11>2014 17:41 Sep 02, 2022 Jkt 256001 sources internal to the airplane, to the airplane’s internal electronic components. Discussion The Bombardier Model BD–700–1A10 and BD–700–1A11 airplanes 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 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 PO 00000 Frm 00042 Fmt 4700 Sfmt 4700 that established by the existing airworthiness standards. Applicability As discussed above, these special conditions are applicable to the Bombardier Model BD–700–1A10 and BD–700–1A11 airplanes. 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. T00003NY 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 Bombardier Model BD–700–1A10 and BD–700–1A11 airplanes. 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.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain MHI RJ Aviation ULC Model CL–600–2D24 (Regional Jet Series 900) airplanes. The NPRM published in the Federal Register on June 2, 2022 (87 FR 33454). The NPRM was prompted by AD CF–2021–31, dated September 14, 2021, issued by Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada (referred to after this as the MCAI). The MCAI states that a manufacturing error may have resulted in dents on the lower wing plank, close to the five flap arm locations at wing station (WS) 54.55, WS 128.00, WS 179.00, WS 220.00, and WS 264.00. These dents could lead to cracks that could weaken the structural integrity of the wings before being detected by any existing required inspection. In the NPRM, the FAA proposed to require an inspection for damage PO 00000 Frm 00043 Fmt 4700 Sfmt 4700 54353 (including dents, cracks, discoloration, gouges, scratches, or other surface damage) of the lower wing plank in the flap arm areas at certain wing stations, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products. You may examine the MCAI in the AD docket at regulations.gov under Docket No. FAA–2022–0592. Discussion of Final Airworthiness Directive Comments The FAA received no comments on the NPRM or on the determination of the cost to the public. Conclusion This product has been approved by the aviation authority of another country and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI referenced above. The FAA reviewed the relevant data and determined that air safety requires adopting this AD as proposed. Accordingly, the FAA is issuing this AD to address the unsafe condition on this product. Except for minor editorial changes, this AD is adopted as proposed in the NPRM. None of the changes will increase the economic burden on any operator. Related Service Information Under 1 CFR Part 51 The FAA reviewed MHI RJ Aviation Service Bulletin 670BA–57–029, dated February 2, 2021. This service information specifies procedures for, among other actions, doing a detailed visual inspection for damage (including dents, cracks, discoloration, gouges, scratches, or other surface damage) of the outer aft lower skin at WS 54.55, WS 128.00, WS 179.00, WS 220.00, and WS 264.00, and repair. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. Costs of Compliance The FAA estimates that this AD affects 14 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\06SER1.SGM 06SER1

Background

    On October 1, 2021, L2 Consulting Services, Inc., applied for a 
supplemental type certificate for the installation of a digital system 
that

[[Page 54352]]

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 BD-700-1A10 and BD-700-1A11 airplanes are twin-engine 
business jets with a maximum takeoff weight of 93,500 pounds (42,410 
Kg) and a maximum seating capacity of seventeen 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 BD-700-1A10 and BD-700-1A11 airplanes, as changed, continue to 
meet the applicable provisions of the regulations listed in Type 
Certificate No. T00003NY, 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., 14CFR part25) do not contain adequate or appropriate 
safety standards for the Bombardier Model BD-700-1A10 and BD-700-1A11 
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 Bombardier Model BD-700-1A10 and BD-700-1A11 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 Bombardier Model BD-700-1A10 and BD-700-1A11 airplanes 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 BD-700-1A10 and BD-700-1A11 airplanes 
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 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 BD-700-1A10 and BD-700-1A11 airplanes. 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. T00003NY 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 Bombardier Model BD-700-1A10 and BD-700-1A11 airplanes. 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.

Administrator, the following special conditions are issued as part of 
the type certification basis for Bombardier Model BD-700-1A10 and BD-
700-1A11 airplanes for airplane electronic-system internal access.
    1. 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, and other assets required 
for safe flight and operations.
    2. 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.
