These special conditions are issued for the Textron Aviation Inc. (Textron) Model 700 airplane. This airplane will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for transport-category airplanes. This design feature is airplane electronic systems and networks that allow access from external sources (e.g., wireless devices, Internet connectivity) to the airplane's internal electronic components. The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. 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.

[Docket No. FAA-2016-9297; Special Conditions No. 25-648-SC]

Special Conditions: Textron Aviation Inc. Model 700 Airplane;
Airplane Electronic-System Security Protection From Unauthorized
External Access

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final special conditions; request for comments.

-----------------------------------------------------------------------

SUMMARY: These special conditions are issued for the Textron Aviation
Inc. (Textron) Model 700 airplane. This airplane will have a novel or
unusual design feature when compared to the state of technology
envisioned in the airworthiness standards for transport-category
airplanes. This design feature is airplane electronic systems and
networks that allow access from external sources (e.g., wireless
devices, Internet connectivity) to the airplane's internal electronic
components. The applicable airworthiness regulations do not contain
adequate or appropriate safety standards for this design feature. 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.

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 by the closing date for
comments. We may change these special conditions based on the comments
we receive.

Background

On November 20, 2014, Textron applied for a type certificate for
their new Model 700 airplane. The Textron Model 700 airplane is a twin-
engine, transport-category executive airplane with seating for 2
crewmembers and 12 passengers, and a maximum takeoff weight of 38,514
lbs.

Type Certification Basis

Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.17, Textron must show that the Model 700 airplane meets the
applicable provisions of part 25, as amended by Amendments 25-1 through
25-139, 25-141, and 25-143.
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 Textron Model 700 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 Textron Model 700 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(a)(2).

Novel or Unusual Design Features

The Textron Model 700 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 Textron Model 700 airplane allows connection to airplane
electronic systems and networks, and access from airplane external
sources (e.g., operator networks, wireless devices, Internet
connectivity, service-provider satellite communications, electronic
flight bags, etc.) to the airplane's previously isolated, internal,
electronic components. These airplane internal electronic components
include electronic equipment and systems, instruments, networks,
servers, software and electronic components, field-loadable software
and hardware applications, and databases. This proposed design may
otherwise result in network security vulnerabilities, if not
appropriately protected, 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 this type of system architecture, nor external wired and
wireless electronic access to airplane electronic systems. Furthermore,
regulations, and current system safety-assessment policy and
techniques, do not address potential security vulnerabilities that
could be caused by unauthorized access to airplane electronic systems
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
Textron Model 700 airplane. Should Textron 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 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.

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 Textron Model 700 airplanes.

1. The applicant must ensure that the airplane electronic
systems are protected from access by unauthorized sources external
to the airplane, including those possibly caused by maintenance
activity.
2. The applicant must ensure that electronic system-security
threats are identified and assessed, and that effective electronic
system-security protection strategies are implemented to protect the
airplane from all adverse impacts on safety, functionality, and
continued airworthiness.
3. 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.
