58740
Federal Register / Vol. 83, No. 225 / Wednesday, November 21, 2018 / Rules and Regulations
in Textron Model 560XL airplanes. This
is a twin-engine, turbofan airplane with
seating for 12 passengers and two crew
members, and a maximum takeoff
weight of 20,200 pounds.
Type Certification Basis
Under the provisions of title 14, Code
of Federal Regulations (14 CFR) 21.101,
Garmin must show that the Textron
Model 560XL airplane, as changed,
continues to meet the applicable
provisions of the regulations listed in
Type Certificate No. A22CE, 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
(i.e., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for the Textron Model 560XL 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 Textron Model 560XL
airplane must comply with the fuel-vent
and exhaust-emission requirements of
14 CFR part 34, and the noisecertification 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 Features
The Textron Model 560XL airplane,
as modified by Garmin, will incorporate
the following novel or unusual design
features:
Garmin G5000 avionics that allow
internal connection to previously
isolated data networks, which are
connected to systems that perform
functions required for the safe operation
of the airplane.
Discussion
The Textron Model 560XL airplane
architecture is novel or unusual for
commercial transport airplanes because
it allows connection to previously
isolated data networks connected to
systems that perform functions required

for the safe operation of the airplane.
This data network and design
integration creates a potential for
unauthorized persons to access the
aircraft-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 regulations and guidance
material did not anticipate this type of
system architecture or electronic access
to airplane systems. Furthermore, 14
CFR regulations and the current systemsafety assessment policy and techniques
do not address potential security
vulnerabilities, which could be
exploited by unauthorized access to
airplane networks and servers.
Therefore, these special conditions
ensure that the security of airplane
systems and networks is not
compromised by unauthorized wired or
wireless internal access.
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 Textron
Model 560XL airplane. Should Garmin
apply at a later date for a supplemental
type certificate to modify any other
model included on Type Certificate No.
A22CE to incorporate the same novel or
unusual design feature, these special
conditions would apply to that model as
well.
Conclusion
This action affects only certain novel
or unusual design features on one model
of airplane. It is not a rule of general
applicability and affects only the
applicant who applied to the FAA for
approval of the features on the airplane.

Background
On March 21, 2017, Garmin applied
for a supplemental type certificate to
install Garmin G5000 avionics
connected to the aircraft-control domain
and airline information-services domain
in Textron Model 560XL airplanes. This
is a twin-engine, turbofan airplane with
seating for 12 passengers and two crew
members, and a maximum takeoff
weight of 20,200 pounds.

the following novel or unusual design
features:
Garmin G5000 avionics that allow
external connection to previously
isolated data networks, which are
connected to systems that perform
functions required for the safe operation
of the airplane.
Discussion
The Textron Model 560XL airplane
architecture and network configuration
may allow increased connectivity to and
access from external network sources
and airline operations and maintenance
networks to the airplane control domain
and airline information services
domain. The airplane 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
aircraft-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 regulations and guidance
material did not anticipate these types
of airplane system architectures.
Furthermore, 14 CFR regulations and
the current system safety assessment
policy and techniques do not address

potential security vulnerabilities, which
could be exploited by unauthorized
access to airplane networks, data buses,

conditions ensure that the security (i.e.,
confidentiality, integrity, and
availability) of airplane systems is not
compromised by unauthorized wired or
wireless electronic connections.
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:
Authority for This Rulemaking
The FAA’s authority to issue rules
regarding aviation safety is found in
Title 49 of the United States Code.
Subtitle I, Section 106 describes the
authority of the FAA Administrator.
Subtitle VII, Aviation Programs,
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 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 establishes
Class E surface airspace and amends
Class D airspace at Tyndall AFB, FL, to
support IFR operations at this airport.
History
The FAA published a notice of
proposed rulemaking in the Federal
Register (83 FR 45861, September 11,
2018) for Docket No. FAA–2018–0741 to
establish Class E surface airspace and
amend Class D airspace at Tyndall AFB,
FL, to support IFR operations at this
airport.
Interested parties were invited to
participate in this rulemaking effort by
submitting written comments on the
proposal to the FAA. One comment
supporting the action was received.
After the comment period closed, two
additional comments were received that
did not clearly indicate a position in
support of the proposal, or in opposition
to the proposal.
Class D and E airspace designations
are published in Paragraphs 5000 and
6002, respectively, dated August 13,
2018, and effective September 15, 2018,

Background
On March 21, 2017, Garmin applied for a supplemental type
certificate to install Garmin G5000 avionics connected to the aircraft-
control domain and airline information-services domain in Textron Model
560XL airplanes. This is a twin-engine, turbofan airplane with seating
for 12 passengers and two crew members, and a maximum takeoff weight of
20,200 pounds.
Type Certification Basis
Under the provisions of title 14, Code of Federal Regulations (14
CFR) 21.101, Garmin must show that the Textron Model 560XL airplane, as
changed, continues to meet the applicable provisions of the regulations
listed in Type Certificate No. A22CE, 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 (i.e., 14 CFR part 25) do not contain adequate or
appropriate safety standards for the Textron Model 560XL 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 Textron Model 560XL 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 Features
The Textron Model 560XL airplane, as modified by Garmin, will
incorporate the following novel or unusual design features:
Garmin G5000 avionics that allow external connection to previously
isolated data networks, which are connected to systems that perform
functions required for the safe operation of the airplane.
Discussion
The Textron Model 560XL airplane architecture and network
configuration may allow increased connectivity to and access from
external network sources and airline operations and maintenance
networks to the airplane control domain and airline information
services domain. The airplane 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 aircraft-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 regulations and guidance material did not anticipate
these types of airplane system architectures. Furthermore, 14 CFR
regulations and the current system safety assessment policy and
techniques do not address
[[Page 58742]]
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 is
not compromised by unauthorized wired or wireless electronic
connections.
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
Textron Model 560XL airplane. Should Garmin apply at a later date for a
supplemental type certificate to modify any other model included on
Type Certificate No. A22CE to incorporate the same novel or unusual
design feature, these special conditions would apply to that model as
well.
Conclusion
This action affects only certain novel or unusual design features
on one model of airplane. It is not a rule of general applicability and
affects only the applicant who applied to the FAA for approval of the
features on the airplane.
