Abstract
These special conditions are issued for the Bombardier Model BD-100-1A10 airplane. This airplane, as modified by Honeywell, 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 the installation of a system that provides wireless data download capability from the engine electronic control unit to Honeywell cloud-based storage. 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.

SUPPLEMENTARY INFORMATION: The substance of these special conditions
has been published in the Federal Register for public comment in
several prior instances with no substantive comments received.
Therefore, the FAA has determined that prior public notice and comment
are unnecessary, and finds that, for the same reason, good cause exists
for adopting these special conditions upon publication in the Federal
Register.
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 February 24, 2020, Honeywell applied for a supplemental type
certificate for installation of the Honeywell Connected Engine Data
Access System (CEDAS) in the Bombardier Model BD-100-1A10 airplane,
requiring security protection from unauthorized internal access. The
Bombardier Model BD-100-1A10 airplane is a twin-engine business jet
with a passenger capacity of 16 and a maximum takeoff weight of 40,600
pounds.
Type Certification Basis
Under the provisions of title 14 Code of Federal Regulations (14
CFR) 21.101, Honeywell must show that the Bombardier Model BD-100-1A10
airplane, as changed, continues to meet the applicable provisions of
the regulations listed in Type Certificate No. T00005NY 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 BD-100-1A10
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 BD-100-1A10 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 BD-100-1A10 airplane, as modified by
Honeywell, will incorporate the following novel or unusual design
feature:
Installation of the Honeywell Connected Engine Data Access System
(CEDAS) which provides wireless data
[[Page 59842]]
download capability from the engine's electronic control unit (ECU) to
Honeywell cloud-based storage. CEDAS allows maintenance personnel to
wirelessly connect to the ECUs and allows autonomous engine data
uploads to cloud data services over WiFi.
Discussion
The Honeywell supplemental type certificate for the Bombardier
Model BD-100-1A10 airplane design adds the Connected Engine Data Access
System (CEDAS) architecture which is novel for commercial transport
category airplanes. CEDAS allows connection to airplane electronic
systems and networks, and access from aircraft external sources (e.g.,
operator networks, wireless devices, internet connectivity, service
provider satellite communications, electronic flight bags, etc.) to the
previously isolated airplane electronic assets (networks, systems, and
databases). The CEDAS design introduces the potential for unauthorized
access to these previously isolated airplane electronic systems and
networks by persons inside the airplane. The installation of CEDAS may
result in network security vulnerabilities from intentional or
unintentional corruption of data and systems required for the
operations 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 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-100-1A10 airplane. Should Honeywell apply at a
later date for a supplemental type certificate to modify any other
model included on Type Certificate No. T00005NY 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 one model of airplane, as modified by Honeywell. It is not a rule of
general applicability and affects only the applicant.

Authority Citation
The authority citation for these special conditions is as follows:
Authority: 49 U.S.C. 106(f), 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 the Bombardier Model BD-100-1A10
airplane, as modified by Honeywell, for electronic system security
protection from unauthorized 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, or 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.
