Should the type certificate for that model be amended later to include any other model that incorporates the same novel or unusual design feature, or should any other model already included on the same type certificate be modified 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 Model BD–700–2A12 and BD–700–2A13 airplanes must comply with the fuel-vent and exhaustemission 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. asabaliauskas on DSK3SPTVN1PROD with RULES Novel or Unusual Design Features The Model BD–700–2A12 and BD– 700–2A13 airplanes will incorporate the following novel or unusual design feature: A digital-systems network architecture composed of several connected networks. This network architecture and network configuration will have the capability to allow access to or by external network sources, and may be used for or interfaced with a diverse set of functions, including: • Flight-safety-related control, communication, and navigation systems (airplane-control domain); • Operator business and administrative support (operatorinformation domain); and • Passenger information and entertainment systems (passengerentertainment domain). Discussion The Model BD–700–2A12 and BD– 700–2A13 airplanes’ digital-systems network architecture is novel or unusual for commercial transport airplanes as it allows connection to airplane electronic systems and networks, and access from sources external to the airplane (e.g., operator networks, wireless devices, Internet connectivity, service-provider satellite communications, electronic flight bags, etc.) to the previously isolated airplane electronic assets.

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 the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.17, Gulfstream must show that the Model GVII-G500 airplane 
meets the applicable provisions of part 25, as amended by Amendments 
25-1 through 25-137.
    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 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 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 Model GVII-G500 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.  21.17.

Novel or Unusual Design Features

    The Model GVII-G500 airplane will incorporate the following novel 
or unusual design feature: A digital-systems network architecture 
composed of several connected networks. This network architecture and 
network configuration will have the capability to allow access to or by 
external network sources, and may be used for or interfaced with a 
diverse set of functions, including:
     Flight-safety-related control, communication, and 
navigation systems (airplane-control domain);
     Operator business and administrative support (operator-
information domain); and
     Passenger information and entertainment systems 
(passenger-entertainment domain).

Discussion

    The Model GVII-G500 airplane's digital-systems network architecture 
is novel or unusual for commercial transport airplanes as it allows 
connection to airplane electronic systems and networks, and access from 
sources external to the airplane (e.g., operator networks, wireless 
devices, Internet connectivity, service-provider satellite 
communications, electronic flight bags, etc.) to the previously 
isolated airplane electronic assets. Airplane electronic assets include 
electronic equipment and systems, instruments, networks, servers, 
software and electronic components, field-loadable software and 
hardware applications, databases, etc. This proposed design may result 
in network security vulnerabilities from intentional or unintentional 
corruption of data and systems required for the safety, operation, and 
maintenance of the airplane.
    The existing regulations and guidance material did not anticipate 
these types of digital-system architectures, nor access to airplane 
systems. Furthermore,

[[Page 23581]]

14 CFR part 25, and current system-safety assessment policy and 
techniques, do not address potential security vulnerabilities by 
unauthorized access to airplane data busses and servers. Therefore, 
these special conditions are issued to ensure that the security, 
integrity, and availability of airplane systems are not compromised by 
certain wired or wireless electronic connections between airplane data 
busses and networks.
    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 
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 airplane. 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 impracticable, 
and good cause exists for adopting these special conditions upon 
issuance. 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.
