SUPPLEMENTARY INFORMATION: The substance of these special conditions has been subject 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 PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 and comment are unnecessary and impracticable. In addition, for the reasons stated above, the FAA finds it unnecessary to delay the effective date and finds that good cause exists for making these special conditions effective upon publication in the Federal Register. Comments Invited We invite interested people to take part in this rulemaking by sending written comments, data, or views. The most helpful comments reference a specific portion of the special conditions, explain the reason for any recommended change, and include supporting data. 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 December 8, 2016, ALOFT applied for a supplemental type certificate for installing a Wireless Access Point (WAP), and connection of an improved Wireless Quick Access Recorder (WQAR) to the satellite communications (SATCOM) system, in a Boeing Model 737–800 airplane. The Boeing Model 737–800 airplane is a twin jet engine, short-to-medium-range passenger airplane with a maximum takeoff weight of 174,200 pounds and seating for 189 passengers. Type Certification Basis Under the provisions of Title 14, Code of Federal Regulations (14 CFR) 21.101, ALOFT must show that the Boeing Model 737–800, as changed, continues to meet the applicable provisions of the regulations listed in Type Certificate No. A16WE 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 (i.e., 14 CFR part 25) do not contain adequate or appropriate safety standards for the Boeing Model 737–800 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 applicant apply for a supplemental type certificate to E:\FR\FM\17OCR1.SGM 17OCR1 48194 Federal Register / Vol. 82, No. 199 / Tuesday, October 17, 2017 / Rules and Regulations modify any other model included on the same type certificate, 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 Boeing Model 737–800 airplane 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 14 CFR 11.19, in accordance with § 11.38, and they become part of the type certification basis under § 21.101. nlaroche on DSK9F9SC42PROD with RULES Novel or Unusual Design Features The Boeing Model 737–800 airplane will incorporate the following novel or unusual design features: A Wireless Access Point (WAP), and connection of an improved Wireless Quick Access Recorder (WQAR) to the satellite communications (SATCOM) system, to provide in-flight access to information, in the WQAR, to ground personnel. Discussion The applicant supplemental type certificate (STC) for the Boeing Model 737–800 airplane design adds wired and wireless access points to the aircraftcontrol domain and airline-informationservices domain networks, which do not exist on current airplanes. The aircraftcontrol 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 other systems. The airline-information services domain generally consists of functions that are managed or controlled by the operator, such as administrative functions and cabin-support functions. This design creates a potential for unauthorized access to aircraft-control and airline-information-services domains, as well as security vulnerabilities related to the introduction of viruses, worms, user mistakes, and intentional sabotage of airplane electronic assets such as networks, systems, and databases. Historically, the operating systems for current airplanes are proprietary. Therefore, they are not as susceptible to corruption from worms, viruses and VerDate Sep<11>2014 14:55 Oct 16, 2017 Jkt 244001 other malicious actions as are more widely used commercial operating systems, such as Microsoft Windows, because access to the design details of the proprietary operating system is limited to the system developer and airplane integrator. Some systems installed on the Boeing Model 737–800 airplane, as modified by ALOFT, 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 currently used by avionics manufacturers. The increased networking of systems based on these popular operating systems increases the opportunity for attack by a larger community, especially those using scripted attacks. While the FAA has developed policy and guidance on the use and protection of certain databases and software, these documents did not anticipate the potential for access to the airplane systems, networks, and software components by external systems, and the resulting potential security vulnerabilities from access by unauthorized users or from the potential corruption of airplane system software resources (applications, databases, configuration files, etc.) by worms, viruses or other malicious entities. The major differences between the applicant’s STC for the Boeing Model 737–800 airplane implementation and typical implementations include: 1. The electronic transmission of updates to airplane servers of databases and software applications using ground data networks rather than physically controlled media. 2. The connection of external data networks or devices to airplane data networks of the Aircraft Control Domain and the Airline Information Services Domain, which may use wired or wireless connections. 3. The connection of wireless devices operated by the flight crew or operator maintenance personnel to the airplane data networks of the Aircraft Control Domain, and connections between the Airline Information Services Domain (including unprotected electronic flight bags and maintenance computers) and the Aircraft Control Domain. 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. PO 00000 Frm 00002 Fmt 4700 Sfmt 9990 Applicability As discussed above, these special conditions are applicable to the Boeing Model 737–800 airplane. Should ALOFT apply at a later date for a supplemental type certificate to modify any other model included on Type Certificate No. A16WE to incorporate the same novel or unusual design feature, these 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 and affects only the applicant who applied to the FAA for approval of these features on the airplane.

unnecessary to delay the effective date and finds that good cause 
exists for making these special conditions effective upon publication 
in the Federal Register.

Comments Invited

    We invite interested people to take part in this rulemaking by 
sending written comments, data, or views. The most helpful comments

reason for any recommended change, and include supporting data.
    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 December 8, 2016, ALOFT applied for a supplemental type 
certificate for installing a Wireless Access Point (WAP), and 
connection of an improved Wireless Quick Access Recorder (WQAR) to the 
satellite communications (SATCOM) system, in a Boeing Model 737-800 
airplane. The Boeing Model 737-800 airplane is a twin jet engine, 
short-to-medium-range passenger airplane with a maximum takeoff weight 
of 174,200 pounds and seating for 189 passengers.

Type Certification Basis

    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.101, ALOFT must show that the Boeing Model 737-800, as changed, 
continues to meet the applicable provisions of the regulations listed 
in Type Certificate No. A16WE 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 (i.e., 14 CFR part 25) do not contain adequate or 
appropriate safety standards for the Boeing Model 737-800 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 applicant apply for a supplemental type 
certificate to

[[Page 48194]]

modify any other model included on the same type certificate, to 
incorporate 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 Boeing Model 737-800 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.  21.101.

Novel or Unusual Design Features

    The Boeing Model 737-800 airplane will incorporate the following 
novel or unusual design features:
    A Wireless Access Point (WAP), and connection of an improved 
Wireless Quick Access Recorder (WQAR) to the satellite communications 
(SATCOM) system, to provide in-flight access to information, in the 
WQAR, to ground personnel.

Discussion

    The applicant supplemental type certificate (STC) for the Boeing 
Model 737-800 airplane design adds wired and wireless access points to 
the aircraft-control domain and airline-information-services domain 
networks, which do not exist on current airplanes. 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 other systems.
    The airline-information services domain generally consists of 
functions that are managed or controlled by the operator, such as 
administrative functions and cabin-support functions.
    This design creates a potential for unauthorized access to 
aircraft-control and airline-information-services domains, as well as 
security vulnerabilities related to the introduction of viruses, worms, 
user mistakes, and intentional sabotage of airplane electronic assets 
such as networks, systems, and databases.
    Historically, the operating systems for current airplanes are 
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, because access 
to the design details of the proprietary operating system is limited to 
the system developer and airplane integrator. Some systems installed on 
the Boeing Model 737-800 airplane, as modified by ALOFT, 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 currently used by avionics 
manufacturers. The increased networking of systems based on these 
popular operating systems increases the opportunity for attack by a 
larger community, especially those using scripted attacks.
    While the FAA has developed policy and guidance on the use and 
protection of certain databases and software, these documents did not 
anticipate the potential for access to the airplane systems, networks, 
and software components by external systems, and the resulting 
potential security vulnerabilities from access by unauthorized users or 
from the potential corruption of airplane system software resources 
(applications, databases, configuration files, etc.) by worms, viruses 
or other malicious entities.
    The major differences between the applicant's STC for the Boeing 
Model 737-800 airplane implementation and typical implementations 
include:
    1. The electronic transmission of updates to airplane servers of 
databases and software applications using ground data networks rather 
than physically controlled media.
    2. The connection of external data networks or devices to airplane 
data networks of the Aircraft Control Domain and the Airline 
Information Services Domain, which may use wired or wireless 
connections.
    3. The connection of wireless devices operated by the flight crew 
or operator maintenance personnel to the airplane data networks of the 
Aircraft Control Domain, and connections between the Airline 
Information Services Domain (including unprotected electronic flight 
bags and maintenance computers) and the Aircraft Control Domain.
    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 
Boeing Model 737-800 airplane. Should ALOFT apply at a later date for a 
supplemental type certificate to modify any other model included on 
Type Certificate No. A16WE to incorporate the same novel or unusual 
design feature, these 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 and affects only the applicant who applied to the FAA for 
approval of these features on the airplane.
