Background On May 15, 2020, Learjet applied for a supplemental type certificate to install an Aircraft Health Management System (AHMS) in the airplanes listed on the approved model list (AML) for STC No. ST01970WI. These airplanes are supermidsize-category business jets with maximum passenger capacity of 16. These airplanes have a maximum takeoff weight of 38,850 pounds.

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 § 21.16. Special conditions are initially applicable to the models for which they are issued. Should the applicant apply for a supplemental type certificate to modify any other models included on the same type certificate to incorporate the same novel or unusual design feature, these special conditions would also apply to the other models under § 21.101. In addition to the applicable airworthiness regulations and special conditions, the airplanes listed in the AML 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 § 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 airplanes listed on the AML in STC no. ST01970WI will incorporate the following novel or unusual design features: The installation of an AHMS that allows connection to airplane electronics 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). lotter on DSK11XQN23PROD with RULES1 Discussion The architecture and network configuration of the airplanes listed on the AML of STC no.

The airplanes’ control domain VerDate Sep<11>2014 17:08 Jan 11, 2022 Jkt 256001 and airline information-services domain perform functions required for the safe operation and maintenance of the airplanes. 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 airplanes. 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 airplane systems is not compromised by unauthorized wired or wireless electronic connections. This includes ensuring that the security of the airplanes’ systems is not compromised during maintenance of airplane 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 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 airplanes listed in the AML of STC no. ST01970WI.

Background

    On May 15, 2020, Learjet applied for a supplemental type 
certificate to install an Aircraft Health Management System (AHMS) in 
the airplanes listed on the approved model list (AML) for STC No. 
ST01970WI. These airplanes are super-midsize-category business jets 
with maximum passenger capacity of 16. These airplanes have a maximum 
takeoff weight of 38,850 pounds.

Type Certification Basis

    Under the provisions of 14 CFR 21.101, Learjet must show that 
airplanes for which they make application to modify by STC no. 
ST01970WI, as changed, continue to meet the applicable provisions of 
the regulations

[[Page 1663]]

listed in each airplane's respective type certificate 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 models for which 
they are issued. Should the applicant apply for a supplemental type 
certificate to modify any other models included on the same type 
certificate to incorporate the same novel or unusual design feature, 
these special conditions would also apply to the other models under 
Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the airplanes listed in the AML 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 Sec.  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 airplanes listed on the AML in STC no. ST01970WI will 
incorporate the following novel or unusual design features:
    The installation of an AHMS that allows connection to airplane 
electronics 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).

Discussion

    The architecture and network configuration of the airplanes listed 
on the AML of STC no. ST01970WI are novel or unusual for commercial 
transport airplanes because they may allow increased connectivity to 
and access from external network sources, airline operations, and 
maintenance networks to the airplanes' control domain and airline 
information-services domain. The airplanes' control domain and airline 
information-services domain perform functions required for the safe 
operation and maintenance of the airplanes. 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 airplanes.
    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 is not compromised by 
unauthorized wired or wireless electronic connections. This includes 
ensuring that the security of the airplanes' systems is not compromised 
during maintenance of airplane 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 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 
airplanes listed in the AML of STC no. ST01970WI. Should Learjet apply 
at a later date for another STC, to include another airplane model with 
the same novel or unusual design feature, these special conditions 
would also apply to that model as well. These special conditions are 
not applicable to those airplane models for which special conditions 
for protection from unauthorized external access have already been 
issued to the type certificate for those specific models.
    These special conditions are only applicable to design changes 
applied for after its effective date.

Conclusion

    This action affects only a certain novel or unusual design feature 
for airplane models listed on the AML of STC no. ST01970WI, as modified 
by Learjet. It is not a rule of general applicability and affects only 
the applicant.
