Background
On April 15, 2024, Canard applied for
a supplemental type certificate to install
a digital systems architecture on the
DeHavilland Model DHC–8–400 series
airplane that will allow increased
connectivity to and access from external
network sources (e.g., operator
networks, wireless devices, internet
connectivity, service provider satellite
communications, electronic flight bags,
etc.) to the airplane’s previously isolated
electronic assets (networks, systems,
and databases). The DeHavilland Model
DHC–8–400 series airplane is a twinengine airplane with a passenger
capacity of 68 and a maximum takeoff
weight of 61,700 pounds.
Type Certification Basis
Under the provisions of title 14, Code
of Federal Regulations (14 CFR) 21.101,
Canard must show that the Model
DeHavilland DHC–8–400 series
airplane, as changed, continues to meet
the applicable provisions of the
regulations listed in Type Certificate No.

The Model DeHavilland DHC–8–400
series airplane, as modified by Canard,
will incorporate the following novel or
unusual design feature(s):
The installation of a digital systems
architecture that will allow increased
connectivity to and access from external
network sources, (e.g., operator
networks, wireless devices, internet
connectivity, service provider satellite
communications, electronic flight bags,
etc.) to the airplane’s previously isolated
electronic assets (networks, systems,
and databases).
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 the airplane’s systems is
not compromised by unauthorized
wired or wireless electronic
connections. This includes ensuring
that the security of the airplane’s
systems is not compromised during
maintenance of the airplane’s electronic
systems. 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
introduce 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.
Discussion
Applicability
The DeHavilland Model DHC–8–400
series airplanes electronic system
architecture and network configuration
change is novel or unusual for
commercial transport airplanes because
it may allow increased connectivity to
and access from external network
sources, airline operations, and
maintenance networks, to the airplane
control domain, and airline information
services domain. The airplane’s control
domain and airline information-services
domain perform functions required for
the safe operation and maintenance of
the airplane. Previously, these domains
had very limited connectivity with
external network sources. This data
network and design integration creates a
potential for unauthorized persons to
access the airplane’s control domain
and airline information-services domain
As discussed above, these special
conditions are applicable to the
DeHavilland DHC–8–400 series
airplane, as modified by Canard. Should
Canard apply at a later date for a
supplemental type certificate to modify
any other model included on Type
Certificate No. A13NM to incorporate
the same novel or unusual design
feature, these special conditions would
apply to that model as well.
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 DeHavilland DHC–8–
400 series airplane must comply with
the 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.

Conclusion
This action affects only a certain
novel or unusual design feature for the
DeHavilland Model DHC–8–400 series

a rule of general applicability and
affects only the applicant who applied
to the FAA for approval of these features

describes in more detail the scope of the
agency’s authority. This rulemaking is
promulgated under the authority
described in Subtitle VII, Part A,
Subpart I, Section 40103. Under that
section, the FAA is charged with
prescribing regulations to assign the use
of the airspace necessary to ensure the
safety of aircraft and the efficient use of
airspace. This regulation is within the

scope of that authority as it modifies the
Air Traffic Service (ATS) route structure
as necessary to preserve the safe and
efficient flow of air traffic within the
National Airspace System.
History
The FAA published an NPRM for
Docket No. FAA–2023–2194 in the
Federal Register (88 FR 77238;
November 9, 2023), proposing to amend
VOR Federal Airways V–5, V–47, V–97,
V–128, V–275, and V–517, and U.S.
RNAV Route T–315; and revoke VOR
Federal Airway V–19 due to the
planned decommissioning of the VOR
portion of the Cincinnati, KY, VORTAC
NAVAID. Interested parties were invited
to participate in this rulemaking effort
by submitting written comments on the
proposal. No comments were received.
Differences From the NPRM
Subsequent the NPRM, the FAA
published a final rule for Docket No.
FAA–2023–1737 in the Federal Register
(89 FR 42795; May 16, 2024), amending
VOR Federal Airway V–128 by
removing the airway segment between
the Cincinnati, KY (reflected as OH in
that final rule), VORTAC and the
Charleston, WV, VORTAC.
Additionally, that final rule amended
U.S. RNAV Route T–315 by extending
the route westward from the JARLO,
WV, Waypoint (WP) to the JIMUR, KY,
Fix and included the CALIF, KY, Fix
and the ILILE, OH, WP in the extension.
Those route amendments were effective
July 11, 2024, and are included in this
final rule.
Additionally, subsequent the NPRM,
the FAA published a final rule for
Docket No. FAA–2024–1848 in the
Federal Register (90 FR 9216; February
10, 2025), amending VOR Federal
Airway V–97 by removing the airway
segment between the Dolphin, FL,
VORTAC and the St. Petersburg, FL,
VORTAC. That airway amendment is
effective April 17, 2025, and is also
included in this final rule.
Finally, the NPRM addressed the VOR
Federal Airway V–97 proposed airway
amendments in the preamble, but the
‘‘as amended’’ airway information did
not match the description in the
regulatory text for the airway. The
proposed amendments to V–97 removed
the airway segment between the
Lexington, KY, VOR/Distance
Measuring Equipment (VOR/DME) and
the intersection of the Chicago Heights,
IL, VORTAC 358° and DuPage, IL, VOR/
DME 101° radials (NILES Fix). As
amended, the correct V–97 airway
description in the NPRM should have
reflected the airway would extend
between the Dolphin VORTAC and the

Background
On April 15, 2024, Canard applied for a supplemental type
certificate to install a digital systems architecture on the
DeHavilland Model DHC-8-400 series airplane that will allow increased
connectivity to and access from external network sources (e.g.,
operator networks, wireless devices, internet connectivity, service
provider satellite communications, electronic flight bags, etc.) to the
airplane's previously isolated electronic assets (networks, systems,
and databases). The DeHavilland Model DHC-8-400 series airplane is a
twin-engine airplane with a passenger capacity of 68 and a maximum
takeoff weight of 61,700 pounds.
Type Certification Basis
Under the provisions of title 14, Code of Federal Regulations (14
CFR) 21.101, Canard must show that the Model DeHavilland DHC-8-400
series airplane, as changed, continues to meet the applicable
provisions of the regulations listed in Type Certificate No. A13NM 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 listed 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 DeHavilland DHC-8-400 series airplane must comply with
the 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 Features
The Model DeHavilland DHC-8-400 series airplane, as modified by
Canard, will incorporate the following novel or unusual design
feature(s):
The installation of a digital systems architecture that will allow
increased connectivity to and access from external network sources,
(e.g., operator networks, wireless devices, internet connectivity,
service provider satellite communications, electronic flight bags,
etc.) to the airplane's previously isolated electronic assets
(networks, systems, and databases).
Discussion
The DeHavilland Model DHC-8-400 series airplanes electronic system
architecture and network configuration change is novel or unusual for
commercial transport airplanes because it may allow increased
connectivity to and access from external network sources, airline
operations, and maintenance networks, to the airplane control domain,
and airline information services domain. The airplane's control domain
and airline information-services domain perform functions required for
the safe operation and maintenance of the airplane. Previously, these
domains had very limited connectivity with external network sources.
This data network and design integration creates a potential for
unauthorized persons to access the airplane's control domain and
airline information-services domain 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 the airplane's systems is not compromised by
unauthorized wired or wireless electronic connections. This includes
ensuring that the security of the airplane's systems is not compromised
during maintenance of the airplane's electronic systems. 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 introduce 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
DeHavilland DHC-8-400 series airplane, as modified by Canard. Should
Canard apply at a later date for a supplemental type certificate to
modify any other model included on Type Certificate No. A13NM 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
for the DeHavilland Model DHC-8-400 series airplanes, modified by
Canard. It is not a rule of general applicability and affects only the
applicant who applied to the FAA for approval of these features on the
airplane.
