Abstract
These special conditions are issued for the Bombardier Model BD-700-1A10 and BD-700-1A11 airplanes. These airplanes, as modified by L2 Consulting Services, Inc., 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 associated with 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 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.

comments received.
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:
<bullet> flight-safety related control and navigation systems,
<bullet> airline business and administrative support, and
<bullet> 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.

The Special Conditions
0
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 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.
