[[Page 10327]]

airplanes. These airplanes, as modified by The Boeing Company, will 
have a novel or unusual design feature associated with airplane 
electronic-system security protection or isolation from unauthorized 
internal access. The applicable airworthiness regulations do not

FOR FURTHER INFORMATION CONTACT: Varun Khanna, FAA, Airplane and 
Flightcrew Interface Branch, ANM-111, Transport Airplane Directorate, 
Aircraft Certification Service, 1601 Lind Avenue SW., Renton, 
Washington 98057-3356; telephone (425) 227-1298; facsimile (425) 227-
1320.

SUPPLEMENTARY INFORMATION: The FAA has determined that notice of, and 
opportunity for prior public comment on, these special conditions is 
impracticable because these procedures would significantly delay 
issuance of the design approval and thus delivery of the affected 
airplane. In addition, the substance of these special conditions has 
been subject to the public-comment process in several prior instances 
with no substantive comments received. The FAA therefore 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 on or before the closing 
date for comments. We may change these special conditions based on the 
comments we receive.

Background

    On January 18, 2010, Boeing applied for an amendment to Type 
Certificate No. A1NM to include a new Model 767-2CX series airplane, a 
derivative of the 767-200, which later was renamed 767-2C. Later, 
Boeing requested, and the FAA approved, an extension to the date of 
application for FAA amended type certification to December 22, 2010.
    The Model 767-2C is a freighter airplane equipped with Pratt & 
Whitney PW4062 engines. This freighter has a maximum takeoff weight of 
415,000 pounds and can be configured to carry up to 11 supernumeraries 
(see Exemption No. 10691).

Type-Certification Basis

    The regulations listed in the type certificate are commonly 
referred to as the ``original type-certification basis.'' The 
regulations to be listed in A1NM are as follows:
    Under the provisions of Title 14, Code of Federal Regulations (14 
CFR) 21.101, Boeing must show that the Boeing Model 767-2C series 
airplane meets the applicable provisions of part 25, as amended by 
Amendments 25-1 through 25-130, and 14 CFR 25.1316 at Amendment 25-134, 
except for earlier amendments as agreed upon by the FAA. These 
regulations will be listed in Type Certificate No. A1NM after type-
certification approval of the 767-2C.
    14 CFR part 26 as amended by Amendments 26-1 through 26-6, and any 
later amendments in existence at the time of certification per 14 CFR 
26.5. For any future part 26 Amendments, the holder of this type 
certificate must demonstrate compliance with the applicable sections.
    14 CFR part 34 as amended by Amendments 34-1 through 34-5A, and any 
later amendments in existence at the time of certification.
    14 CFR part 36 as amended by Amendments 36-1 through 36-29, and any 
later amendments in existence at the time of certification.
    The certification basis also 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 adequate or 
appropriate safety standards for the Model 767-2C series airplane 
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, 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 Sec.  21.101.
    In addition to the applicable airworthiness regulations and special 
conditions, the Model 767-2C 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. 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.  21.101.

Novel or Unusual Design Feature

    The Boeing Model 767-2C series airplane will incorporate the 
following novel or unusual design feature:

[[Page 10328]]

    The electronic-system network architecture for the Model 767-2C 
series airplane introduces potential security risks and vulnerabilities 
not addressed in current regulations and airplane-level or system-level 
safety-assessment methods.
    This network architecture allows connection to previously isolated 
data networks connected to systems that perform functions required for 
the safe operation of the airplane. This data network and design 
integration may result in security vulnerabilities from intentional or 
unintentional internal-connection corruption of data and systems 
critical to the safety and maintenance of the airplane.

Discussion

    The Boeing Model 767-2C series airplane design introduces the 
potential for unauthorized persons to access, from internal connection, 
airplane-control domain and operator-information-services domain in the 
passenger-services domain. The Model 767-2C design further introduces 
the potential for security vulnerabilities related to the introduction 
of viruses, worms, user mistakes, and intentional sabotage of airplane 
networks, systems, and databases. As such, these special conditions 
address these vulnerabilities.
    The digital systems architecture for the Boeing Model 767-2C series 
airplanes is composed of several connected networks. This network 
architecture is used for a diverse set of functions, including:
    1. Flight-safety related control and navigation systems,
    2. operator business and administrative support, and
    3. passenger entertainment.
    The existing regulations and guidance material did not anticipate 
this type of system architecture or electronic access to airplane 
systems. Furthermore, regulations, and current system safety-assessment 
policy and techniques, do not address potential security 
vulnerabilities, which could be caused by unauthorized access to 
airplane data buses and servers. These special conditions are meant to 
ensure that security, integrity, and availability of airplane systems 
are not compromised by certain wired or wireless electronic connections 
between airplane data busses and networks.
    Special conditions have been applied on past airplane programs to 
require consideration of related security vulnerabilities. These 
special conditions are similar to those previously applied, except that 
the scope has been adjusted to be consistent with those features unique 
to the Model 767-2C series airplane.

Applicability

    As discussed above, these special conditions apply to Boeing Model 
767-2C series airplanes. Should Boeing apply later 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 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, 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 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.

List of Subjects in 14 CFR part 25

    Aircraft, Aviation safety, Reporting and recordkeeping 
requirements.

    The authority citation for these special conditions is as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701, 44702, 44704.

The Special Conditions

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the following special conditions are issued as part of 
the type-certification basis for Boeing Model 767-2C series airplanes.
    1. The applicant must ensure that the design provides isolation 
from, or airplane electronic-system security protection against, access 
by unauthorized sources internal to the airplane. The design must 
prevent inadvertent and malicious changes to, and all adverse impacts 
upon, airplane equipment, systems, networks, or other assets required 
for safe flight and operations.
    2. The applicant must establish appropriate procedures to allow the 
operator to ensure that continued airworthiness of the airplane is 
maintained, including all post-type-certification modifications that 
may have an impact on the approved electronic-system security 
safeguards.
