We may change these special E:\FR\FM\10DER1.SGM 10DER1 73994 Federal Register / Vol. 78, No. 237 / Tuesday, December 10, 2013 / Rules and Regulations conditions based on the comments we receive. maindgalligan on DSK5TPTVN1PROD with RULES Background On September 21, 2010, Cessna Aircraft Company applied for an amendment to Model 680 Type Certificate No. T00012WI. The Model 680 ‘‘New Sovereign’’ is a twin-engine pressurized executive jet airplane with standard seating provisions for 14 passenger/crew and allowance for baggage and optional equipment. It will have a maximum takeoff weight of 30,775 pounds with a wingspan of 72.3 feet, a maximum operating altitude of 47,000 feet, and will have two aft-mounted Pratt & Whitney 306D engines. The proposed Cessna Model 680 avionics architecture is novel or unusual for executive jet airplanes by allowing connection to airplane electronic systems and networks, and access from aircraft external sources (e.g., wireless devices, Internet connectivity) to the previously isolated airplane electronic assets. Cessna’s proposed design is considered by the FAA to be an architecture which introduces potential security risks and vulnerabilities not addressed in current regulations and aircraft-level or systemlevel safety assessment methods. Consequently, this special condition has been produced to address security and safety issues arising from the use of this type of architecture, and foreseeable flight and maintenance applications impacted by these interconnected data networks and the addition of external access points. Type Certification Basis Under Title 14, Code of Federal Regulations (14 CFR) 21.17, Cessna must show that the Model 680 series meets the applicable provisions of 14 CFR part 25, as amended by Amendments 25–1 through 25–128. The certification basis for the 680 (S/N –000501 and on) is documented and agreed to within the Cessna Aircraft Company Model 680 Block Point Change G–1 Issue Paper. 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 680 series because of a novel or unusual design feature, special conditions are prescribed under § 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, the proposed special VerDate Mar<15>2010 16:56 Dec 09, 2013 Jkt 232001 conditions would also apply to the other model under § 21.101. In addition to the applicable airworthiness regulations and proposed special conditions, the Cessna Model 680 series 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 and 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, under § 11.38, and they become part of the typecertification basis under § 21.17(a)(2). Novel or Unusual Design Features The Cessna Model 680 will incorporate the following novel or unusual design features: Digital systems architecture composed of several connected networks. The proposed architecture and network configuration may be used for, or interfaced with, a diverse set of functions, including: 1. Flight-safety related control, communication, display, monitoring, and navigation systems (aircraft control functions); 2. Operator business and administrative support (operator information services); 3. Passenger information and entertainment systems (passenger entertainment services); and, 4. The capability to allow access to or by systems external to the airplane. Discussion The architecture and network configuration in the Cessna Model 680 Series airplanes may allow increased connectivity to, or access by, external airplane sources, airline operations, and maintenance systems to the aircraft control functions and airline information services. The aircraft control functions and airline information services perform functions required for the safe operation and maintenance of the airplane. Previously these functions and services had very limited connectivity with external sources. The architecture and network configuration may allow the exploitation of network security vulnerabilities resulting in intentional or unintentional destruction, disruption, degradation, or exploitation of data, systems, and networks critical to the safety and maintenance of the airplane. This configuration may also include the electronic transmission of field-loadable software (and hardware) applications and databases to the airplane, which would subsequently be loaded into the safety-related equipment and systems. PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 The existing regulations and guidance material did not anticipate these types of airplane system architectures. Furthermore, 14 CFR regulations and current system safety assessment policy and techniques do not address potential security vulnerabilities, which could be exploited by unauthorized access to airplane systems, data buses, and servers. Therefore, these special conditions are issued to ensure that the security (i.e., confidentiality, integrity, and availability) of airplane systems is not compromised by unauthorized wired or wireless electronic connections. For the reasons discussed above, 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 Cessna Model 680 Series airplanes. Should Cessna apply at a later date for a change to the type certificate to include another model incorporating the same novel or unusual design feature, the special conditions would apply to that model as well. Conclusion This action affects only certain novel or unusual design features 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.

conditions based on the comments we receive.

Background

    On September 21, 2010, Cessna Aircraft Company applied for an 
amendment to Model 680 Type Certificate No. T00012WI.
    The Model 680 ``New Sovereign'' is a twin-engine pressurized 
executive jet airplane with standard seating provisions for 14 
passenger/crew and allowance for baggage and optional equipment. It 
will have a maximum takeoff weight of 30,775 pounds with a wingspan of 
72.3 feet, a maximum operating altitude of 47,000 feet, and will have 
two aft-mounted Pratt & Whitney 306D engines.
    The proposed Cessna Model 680 avionics architecture is novel or 
unusual for executive jet airplanes by allowing connection to airplane 
electronic systems and networks, and access from aircraft external 
sources (e.g., wireless devices, Internet connectivity) to the 
previously isolated airplane electronic assets. Cessna's proposed 
design is considered by the FAA to be an architecture which introduces 
potential security risks and vulnerabilities not addressed in current 
regulations and aircraft-level or system-level safety assessment 
methods. Consequently, this special condition has been produced to 
address security and safety issues arising from the use of this type of 
architecture, and foreseeable flight and maintenance applications 
impacted by these interconnected data networks and the addition of 
external access points.

Type Certification Basis

    Under Title 14, Code of Federal Regulations (14 CFR) 21.17, Cessna 
must show that the Model 680 series meets the applicable provisions of 
14 CFR part 25, as amended by Amendments 25-1 through 25-128. The 
certification basis for the 680 (S/N -000501 and on) is documented and 
agreed to within the Cessna Aircraft Company Model 680 Block Point 
Change G-1 Issue Paper.
    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 680 series because of a 
novel or unusual design feature, special conditions are prescribed 
under 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, the proposed special conditions would also 
apply to the other model under Sec.  21.101.
    In addition to the applicable airworthiness regulations and 
proposed special conditions, the Cessna Model 680 series 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 and 
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, 
under Sec.  11.38, and they become part of the type-certification basis 
under Sec.  21.17(a)(2).

Novel or Unusual Design Features

    The Cessna Model 680 will incorporate the following novel or 
unusual design features: Digital systems architecture composed of 
several connected networks. The proposed architecture and network 
configuration may be used for, or interfaced with, a diverse set of 
functions, including:
    1. Flight-safety related control, communication, display, 
monitoring, and navigation systems (aircraft control functions);
    2. Operator business and administrative support (operator 
information services);
    3. Passenger information and entertainment systems (passenger 
entertainment services); and,
    4. The capability to allow access to or by systems external to the 
airplane.

Discussion

    The architecture and network configuration in the Cessna Model 680 
Series airplanes may allow increased connectivity to, or access by, 
external airplane sources, airline operations, and maintenance systems 
to the aircraft control functions and airline information services. The 
aircraft control functions and airline information services perform 
functions required for the safe operation and maintenance of the 
airplane. Previously these functions and services had very limited 
connectivity with external sources. The architecture and network 
configuration may allow the exploitation of network security 
vulnerabilities resulting in intentional or unintentional destruction, 
disruption, degradation, or exploitation of data, systems, and networks 
critical to the safety and maintenance of the airplane. This 
configuration may also include the electronic transmission of field-
loadable software (and hardware) applications and databases to the 
airplane, which would subsequently be loaded into the safety-related 
equipment and systems. The existing regulations and guidance material 
did not anticipate these types of airplane system architectures. 
Furthermore, 14 CFR regulations and current system safety assessment 
policy and techniques do not address potential security 
vulnerabilities, which could be exploited by unauthorized access to 
airplane systems, data buses, and servers. Therefore, these special 
conditions are issued to ensure that the security (i.e., 
confidentiality, integrity, and availability) of airplane systems is 
not compromised by unauthorized wired or wireless electronic 
connections.
    For the reasons discussed above, 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 
Cessna Model 680 Series airplanes. Should Cessna apply at a later date 
for a change to the type certificate to include another model 
incorporating the same novel or unusual design feature, the special 
conditions would apply to that model as well.

Conclusion

    This action affects only certain novel or unusual design features 
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.
