Federal Aviation Administration
14 CFR Part 25
[Docket No. FAA-2017-0022; Special Conditions No. 25-676-SC]
Special Conditions: Garmin International, Learjet, Inc., Model 35
and 36 Airplanes; 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 Garmin International
(Garmin) for modifications to Learjet, Inc., (Learjet) Model 35 and 36
airplanes. These airplanes, as modified by Garmin, 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 incorporates the Garmin Flight Stream
210 and GTN 6XX/7XX Navigator system into the airplanes. 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.
DATES: This action is effective on Garmin on May 23, 2017. We must
receive your comments by July 7, 2017.

FOR FURTHER INFORMATION CONTACT: Varun Khanna, FAA, Airplane and
Flightcrew Interface, 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 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.
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.
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 October 26, 2015, Garmin applied for a supplemental type
certificate to install the Garmin Flight Stream 210 and GTN 6XX/7XX
Navigator system in Learjet Model 35 and 36 airplanes. These airplanes,
which are currently approved under Type Certificate No. A10CE, are
twin-engine corporate turbojet airplanes with a maximum takeoff weight
of 18,301 lbs., and seating for 8 passengers and 2 crew members.
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, Garmin must show that the Learjet Model 35 and 36
airplanes, as changed, continue to meet the applicable provisions of
the regulations listed in Type Certificate No. A10CE 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 Learjet Model 35 and 36 airplanes
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 modify any other model included on the same type
certificate to incorporate the
[[Page 23492]]
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 Learjet Model 35 and 36 airplanes 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 Learjet Model 35, 35A, 36, and 36A airplanes, as modified by
Garmin, will incorporate the following novel or unusual design feature:
Installation of the Garmin Flight Stream 210 and GTN 6XX/7XX
Navigator system into the airplanes.
Discussion
The Garmin Flight Stream 210 and GTN 6XX/7XX Navigator system
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 previously
isolated airplane electronic assets. Airplane electronic assets include
electronic equipment and systems, instruments, networks, servers,
software and electronic components, field-loadable software and
hardware applications, and databases. This system installation may
result in network security vulnerabilities from intentional or
unintentional corruption of data and systems required for the safety,
operations, 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
Learjet Model 35 and 36 airplanes modified by Garmin. Should Garmin
apply at a later date for a supplemental type certificate, to
incorporate the same novel or unusual design feature for any other
model included on the same type certificate, these special conditions
would apply to that model as well.
Conclusion
This action affects only a certain novel or unusual design feature
on two models of airplanes. It is not a rule of general applicability
and affects only the applicant who applied to the FAA for approval of
this feature on the airplanes.
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 Learjet Model 35 and 36 airplanes
modified by Garmin.
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.
