We will consider all comments we receive by the closing date for comments. We may change these special conditions based on the comments we receive. Background On January 27, 2012, the Boeing Company applied for an amendment to Type Certificate No. A16WE to include new minor models, 737–7, –8, and –9. The Models 737–7, –8, and –9, which are derivatives of the 737–700, –800, –900ER currently approved under Type Certificate No. A16WE, are passenger series airplanes designed to substantially reduce fuel burn and community noise. In addition, the design will include a new CFM LEAP– 1B engine with a 68.4-inch diameter fan, 8-inch longer nose gear to accommodate the larger engine, a relofted tailcone (which requires the elevator to be trimmed and the elevator tab to be relocated outboard to accommodate the new contours), new horizontal stabilizer strakelets, a retractable auxiliary power unit inlet door, fly-by-wire spoilers, strengthened flight deck bulkhead, and a new winglet design. Type Certification Basis Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.101, The Boeing Company must show that the Models 737–700, –700C, –800, –900ER, –7, –8, and –9 series airplanes meet the applicable provisions of the regulations incorporated by reference in Type Certificate No. A16WE or the applicable regulations in effect on the date of application for the change to the type certificate. The regulations incorporated by reference in the type certificate are commonly referred to as the ‘‘original type certification basis.’’ In addition, the certification basis includes certain special conditions, exemptions, or later amended sections of the applicable part that are not relevant to these special conditions. If the Administrator finds that the applicable airworthiness regulations (i.e., 14 CFR part 25) do not contain E:\FR\FM\06JNR1.SGM 06JNR1 Federal Register / Vol. 79, No. 109 / Friday, June 6, 2014 / Rules and Regulations adequate or appropriate safety standards for the 737–700, –700C, –800, –900ER, –7, –8, and –9 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, or should any other model already included on the same type certificate be modified to incorporate the same novel or unusual design feature, the special conditions would also apply to the other model. In addition to the applicable airworthiness regulations and special conditions, the 737–700, –700C, –800, –900ER, –7, –8, and –9 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 § 11.38, and they become part of the type-certification basis under § 21.101. mstockstill on DSK4VPTVN1PROD with RULES Novel or Unusual Design Features The Boeing Models 737–700, –700C, –800, –900ER, –7, –8, and –9 series airplanes will incorporate the following novel or unusual design features: Digital systems architecture composed of several connected networks. This network architecture and network configuration may be used for or interfaced with a diverse set of functions, including: • Flight safety related control, communication, and navigation systems (aircraft control domain); • Operator business and administrative support (operator information domain); and • Passenger information and entertainment systems (passenger entertainment domain), and the capability to allow access to or by external network sources. Discussion The proposed architecture and network configuration of the Models 737–700, –700C, –800, –900ER, –7, –8, and –9 series airplanes may allow increased connectivity to and access from external network sources and operations and maintenance networks to the aircraft control domain and operator information domain. The airplane control domain and operator information domain perform functions required for the safe operation and maintenance of the airplane. Previously VerDate Mar<15>2010 13:35 Jun 05, 2014 Jkt 232001 these domains had very limited connectivity with external network 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. 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 networks, data buses, and servers. Therefore, these special conditions and a means of compliance are proposed to ensure that the security (i.e., confidentiality, integrity, and availability) of airplane systems is not compromised by unauthorized wired or wireless electronic connections. Applicability As discussed above, these special conditions are applicable to the Models 737–700, –700C, –800, –900ER, –7, –8, and –9 series airplanes. Should The Boeing Company 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 certain 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, because a delay would significantly affect the certification of the airplane, 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.

Background

    On January 27, 2012, the Boeing Company applied for an amendment to 
Type Certificate No. A16WE to include new minor models, 737-7, -8, and 
-9. The Models 737-7, -8, and -9, which are derivatives of the 737-700, 
-800, -900ER currently approved under Type Certificate No. A16WE, are 
passenger series airplanes designed to substantially reduce fuel burn 
and community noise. In addition, the design will include a new CFM 
LEAP-1B engine with a 68.4-inch diameter fan, 8-inch longer nose gear 
to accommodate the larger engine, a relofted tailcone (which requires 
the elevator to be trimmed and the elevator tab to be relocated 
outboard to accommodate the new contours), new horizontal stabilizer 
strakelets, a retractable auxiliary power unit inlet door, fly-by-wire 
spoilers, strengthened flight deck bulkhead, and a new winglet design.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.101, The Boeing Company must show that the Models 737-700, -
700C, -800, -900ER, -7, -8, and -9 series airplanes meet the applicable 
provisions of the regulations incorporated by reference in Type 
Certificate No. A16WE or the applicable regulations in effect on the 
date of application for the change to the type certificate. The 
regulations incorporated by reference in the type certificate are 
commonly referred to as the ``original type certification basis.'' In 
addition, the certification basis includes certain special conditions, 
exemptions, or later amended sections of the applicable part that are 
not relevant to these special conditions.
    If the Administrator finds that the applicable airworthiness 
regulations (i.e., 14 CFR part 25) do not contain

[[Page 32641]]

adequate or appropriate safety standards for the 737-700, -700C, -800, 
-900ER, -7, -8, and -9 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, or should any other model already 
included on the same type certificate be modified to incorporate the 
same novel or unusual design feature, the special conditions would also 
apply to the other model.
    In addition to the applicable airworthiness regulations and special 
conditions, the 737-700, -700C, -800, -900ER, -7, -8, and -9 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 Boeing Models 737-700, -700C, -800, -900ER, -7, -8, and -9 
series airplanes will incorporate the following novel or unusual design 
features: Digital systems architecture composed of several connected 
networks. This network architecture and network configuration may be 
used for or interfaced with a diverse set of functions, including:
     Flight safety related control, communication, and 
navigation systems (aircraft control domain);
     Operator business and administrative support (operator 
information domain); and
     Passenger information and entertainment systems (passenger 
entertainment domain), and the capability to allow access to or by 
external network sources.

Discussion

    The proposed architecture and network configuration of the Models 
737-700, -700C, -800, -900ER, -7, -8, and -9 series airplanes may allow 
increased connectivity to and access from external network sources and 
operations and maintenance networks to the aircraft control domain and 
operator information domain. The airplane control domain and operator 
information domain perform functions required for the safe operation 
and maintenance of the airplane. Previously these domains had very 
limited connectivity with external network 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.
    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 networks, data buses, and 
servers. Therefore, these special conditions and a means of compliance 
are proposed to ensure that the security (i.e., confidentiality, 
integrity, and availability) of airplane systems is not compromised by 
unauthorized wired or wireless electronic connections.

Applicability

    As discussed above, these special conditions are applicable to the 
Models 737-700, -700C, -800, -900ER, -7, -8, and -9 series airplanes. 
Should The Boeing Company 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 certain 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, because a delay would 
significantly affect the certification of the airplane, 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.
