Background On March 29, 2012, Gulfstream Aerospace Corporation applied for a type certificate for their new Model GVII–G500 airplane. The Model GVII– G500 airplane will be a business jet capable of accommodating up to 19 passengers. It will incorporate a low, swept-wing design with winglets and a T-tail. The powerplant will consist of two aft-fuselage-mounted Pratt & Whitney turbofan engines. Type Certification Basis Under Title 14, Code of Federal Regulations (14 CFR) 21.17, Gulfstream must show that the Model GVII–G500 airplane meets the applicable provisions of 14 CFR part 25, as amended by Amendments 25–1 through 25–129. If the Administrator finds that the applicable airworthiness regulations (i.e., part 25) do not contain adequate or appropriate safety standards for the Model GVII–G500 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 type certificate for that model be amended later to include any other model that incorporates the same or similar novel or unusual design feature, the special conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and special conditions, Model GVII–G500 airplanes 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 must issue a finding of regulatory adequacy under § 611 of Public Law 92– 574, the ‘‘Noise Control Act of 1972.’’ 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 § 21.17(a)(2). Novel or Unusual Design Features The Model GVII–G500 airplane will incorporate the following novel or unusual design feature: A digital E:\FR\FM\15JYR1.SGM 15JYR1 Federal Register / Vol. 81, No. 136 / Friday, July 15, 2016 / Rules and Regulations rmajette on DSK2TPTVN1PROD with RULES systems architecture requiring isolation or protection from unauthorized internal access. Discussion Networks, both in safety-related and non-safety-related applications, have been implemented in existing commercial-production airplanes. However, network security considerations and functions have played a relatively minor role in the certification of such systems because of the isolation, protection mechanisms, and limited connectivity between these networks. To provide an understanding of the airplane electronic equipment, systems, and assets, these special conditions use the concept of domains. However, this does not prescribe any particular architecture. The aircraft-control domain consists of the airplane electronic systems, equipment, instruments, networks, servers, software and hardware components, databases, etc., which are part of the type design of the airplane and are installed in the airplane to enable the safe operation of the airplane. These can also be referred to as flightsafety-related systems, and include flight controls, communication, display, monitoring, navigation, and related systems. The airline-information-services domain generally consists of functions that the airplane operator manages or controls, such as administrative functions, cabin-support functions, etc. The passenger-information-services domain consists of all functions required to provide the passengers with information. The Gulfstream Model GVII–G500 airplane design introduces the potential for access to aircraft-control domain and airline-information-services domain by unauthorized persons through the passenger-information-services domain; and the security vulnerabilities related to the introduction of viruses, worms, user mistakes, and intentional sabotage of airplane networks, systems, and databases. For electronic systems-and-assets security in these domains, the level of protection provided against security threats should be based on a securityrisk assessment, noting that the level of protection could differ between domains and within domains, depending on the security threat. For each security vulnerability and airplane electronic asset, Gulfstream should identify in which domain the asset will be addressed. In addition, the operating systems for current airplane systems are usually and VerDate Sep<11>2014 15:21 Jul 14, 2016 Jkt 238001 historically proprietary. Therefore, they are not as susceptible to corruption from worms, viruses, and other malicious actions as are more-widely used commercial operating systems, such as Microsoft Windows NT, because access to the design details of these proprietary operating systems is limited to the system developer and airplane integrator. Some systems installed on the Gulfstream Model GVII–500 will use operating systems that are widely used and commercially available from thirdparty software suppliers. The security vulnerabilities of these operating systems may be more widely known than are the vulnerabilities of proprietary operating systems that the avionics manufacturers currently use. Applicability As discussed above, these special conditions are applicable to the Gulfstream Model GVII–G500 airplane. Should Gulfstream apply at a later date for a change to the type certificate to include another model incorporating 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 series of airplanes. It is not a rule of general applicability. The substance of these special conditions has been subjected to the notice and comment period in several prior instances and has been derived without substantive change from those previously issued. It is unlikely that prior public comment would result in a significant change from the substance contained herein. Therefore, the FAA has determined that prior public notice and comment are unnecessary, and good cause exists for adopting these special conditions upon publication in the Federal Register. The FAA is requesting comments to allow interested persons to submit views that may not have been submitted in response to the prior opportunities for comment described above.

Background

    On March 29, 2012, Gulfstream Aerospace Corporation applied for a 
type certificate for their new Model GVII-G500 airplane. The Model 
GVII-G500 airplane will be a business jet capable of accommodating up 
to 19 passengers. It will incorporate a low, swept-wing design with 
winglets and a T-tail. The powerplant will consist of two aft-fuselage-
mounted Pratt & Whitney turbofan engines.

Type Certification Basis

    Under Title 14, Code of Federal Regulations (14 CFR) 21.17, 
Gulfstream must show that the Model GVII-G500 airplane meets the 
applicable provisions of 14 CFR part 25, as amended by Amendments 25-1 
through 25-129.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., part 25) do not contain adequate or appropriate 
safety standards for the Model GVII-G500 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 type certificate for that model be amended 
later to include any other model that incorporates the same or similar 
novel or unusual design feature, the special conditions would also 
apply to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, Model GVII-G500 airplanes 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 must issue a 
finding of regulatory adequacy under Sec.  611 of Public Law 92-574, 
the ``Noise Control Act of 1972.''
    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.  21.17(a)(2).

Novel or Unusual Design Features

    The Model GVII-G500 airplane will incorporate the following novel 
or unusual design feature: A digital

systems architecture requiring isolation or protection from 
unauthorized internal access.

Discussion

    Networks, both in safety-related and non-safety-related 
applications, have been implemented in existing commercial-production 
airplanes. However, network security considerations and functions have 
played a relatively minor role in the certification of such systems 
because of the isolation, protection mechanisms, and limited 
connectivity between these networks.
    To provide an understanding of the airplane electronic equipment, 
systems, and assets, these special conditions use the concept of 
domains. However, this does not prescribe any particular architecture.
    The aircraft-control domain consists of the airplane electronic 
systems, equipment, instruments, networks, servers, software and 
hardware components, databases, etc., which are part of the type design 
of the airplane and are installed in the airplane to enable the safe 
operation of the airplane. These can also be referred to as flight-
safety-related systems, and include flight controls, communication, 
display, monitoring, navigation, and related systems.
    The airline-information-services domain generally consists of 
functions that the airplane operator manages or controls, such as 
administrative functions, cabin-support functions, etc.
    The passenger-information-services domain consists of all functions 
required to provide the passengers with information.
    The Gulfstream Model GVII-G500 airplane design introduces the 
potential for access to aircraft-control domain and airline-
information-services domain by unauthorized persons through the 
passenger-information-services domain; and the security vulnerabilities 
related to the introduction of viruses, worms, user mistakes, and 
intentional sabotage of airplane networks, systems, and databases.
    For electronic systems-and-assets security in these domains, the 
level of protection provided against security threats should be based 
on a security-risk assessment, noting that the level of protection 
could differ between domains and within domains, depending on the 
security threat. For each security vulnerability and airplane 
electronic asset, Gulfstream should identify in which domain the asset 
will be addressed.
    In addition, the operating systems for current airplane systems are 
usually and historically proprietary. Therefore, they are not as 
susceptible to corruption from worms, viruses, and other malicious 
actions as are more-widely used commercial operating systems, such as 
Microsoft Windows NT, because access to the design details of these 
proprietary operating systems is limited to the system developer and 
airplane integrator. Some systems installed on the Gulfstream Model 
GVII-500 will use operating systems that are widely used and 
commercially available from third-party software suppliers. The 
security vulnerabilities of these operating systems may be more widely 
known than are the vulnerabilities of proprietary operating systems 
that the avionics manufacturers currently use.

Applicability

    As discussed above, these special conditions are applicable to the 
Gulfstream Model GVII-G500 airplane. Should Gulfstream apply at a later 
date for a change to the type certificate to include another model 
incorporating 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 series of airplanes. It is not a rule of general 
applicability.
    The substance of these special conditions has been subjected to the 
notice and comment period in several prior instances and has been 
derived without substantive change from those previously issued. It is 
unlikely that prior public comment would result in a significant change 
from the substance contained herein. Therefore, the FAA has determined 
that prior public notice and comment are unnecessary, and good cause 
exists for adopting these special conditions upon publication in the 
Federal Register.
    The FAA is requesting comments to allow interested persons to 
submit views that may not have been submitted in response to the prior 
opportunities for comment described above.
