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. khammond on DSK30JT082PROD with RULES 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.

Comments Invited

    We invite interested people to take part in this rulemaking by 
sending written comments, data, or views. The most helpful comments

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.

threats are identified and assessed, and that effective electronic-
system security protection strategies are implemented to protect the 
airplane from all adverse impacts on safety, functionality, and 
continued airworthiness.
    3. 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.
