T00001SE for the installation of an
Avionica avWIFI system with wireless
network and hosted application
functionality in Boeing Model 777–200/
–200LR/–300/–300ER series airplanes.
These airplanes, currently approved
under Type Certificate No. T00001SE,
are twin-engine, transport category
airplanes, with a maximum takeoff
weight between 535,000 lbs and 775,000
lbs pounds, and a maximum passenger
capacity of 550 persons.
Type Certification Basis
Under the provisions of title 14, Code
of Federal Regulations (14 CFR) 21.101,
Archeion must show that the Boeing
Model 777–200/–200LR/–300/–300ER
series airplanes, as changed, continue to
meet the applicable provisions of the
regulations listed in Type Certificate No.
T00001SE 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
(e.g., 14 CFR part 25) do not contain
adequate or appropriate safety standards
for the Boeing Model 777–200/–200LR/
–300/–300ER series airplanes 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
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 777–200/
–200LR/–300/–300ER series 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 § 11.38, and they become part of
the type certification basis under
§ 21.101.

Novel or Unusual Design Feature
The Boeing Model 777–200/–200LR/–
300/–300ER series airplanes will
incorporate the following novel or
unusual design feature:
A digital systems architecture for the
installation of a system with wireless

Applicability
airplane’s internal electronic
components.
Discussion
The digital systems architecture for
the installation of an Avionica avWIFI
system with wireless network and
hosted application functionality on
these Boeing Model 777 airplanes is a
novel or unusual design feature for
transport category airplanes because it is
composed of several connected
networks. This proposed network
architecture is used for a diverse set of
airplane functions, including:
• Flight-safety related control and
navigation systems,
• airline business and administrative
support, and
• passenger entertainment.
The airplane control domain and
airline information-services domain of
these networks perform functions
required for the safe operation and
maintenance of the airplane. Previously,
these domains had very limited
connectivity with other network
sources. This network architecture
creates a potential for unauthorized
persons to access the aircraft control
domain and airline information-services
domain from sources internal to the
airplane, and presents security
vulnerabilities related to the
introduction of computer viruses and
worms, user errors, and intentional
sabotage of airplane electronic assets
(networks, systems, and databases)
critical to the safety and maintenance of
the airplane.
The existing FAA regulations did not
anticipate these networked airplane
system architectures. Furthermore, these
regulations and the current guidance
material do not address potential
security vulnerabilities, which could be
exploited by unauthorized access to
airplane networks, data buses, and
servers. Therefore, these special
conditions ensure that the security (i.e.,
confidentiality, integrity, and
availability) of airplane systems will not
be compromised by unauthorized wired
or wireless electronic connections from
within the airplane. These special
conditions also require the applicant to
provide appropriate instructions to the
operator to maintain all electronicsystem safeguards that have been
implemented as part of the original
network design so that this feature does
not allow or reintroduce security
threats.
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.

As discussed above, these special
conditions are applicable to the Boeing
Model 777–200/–200LR/–300/–300ER
series airplanes. Should Archeion apply
at a later date for a supplemental type
certificate to modify any other model
included on Type Certificate No.
T00001SE to incorporate 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
Boeing Model 777–200/–200LR/–300/–
300ER series airplanes. It is not a rule
of general applicability and affects only
the applicant.

A–1, MBB–BK 117 A–3, MBB–BK 117
A–4, MBB–BK 117 B–1, MBB–BK 117
B–2, and MBB–BK 117 C–1 helicopters.
The NPRM published in the Federal
Register on April 26, 2021 (86 FR
21965). In the NPRM, the FAA proposed
to require inspections to determine if
any bolted main rotor blades are
installed, and replacement of the
affected main rotor blades. The NPRM
was prompted by a report of sudden
severe vibrations and a cracked open
blade trailing edge caused by a loosened
lead inner weight.
German AD D–2005–115, effective
March 15, 2005 (German AD D–2005–

not addressed, could result in loss of
control of the helicopter.
Accordingly, German AD D–2005–115
requires an inspection and log card
review to determine if any bolted main
rotor blades are installed, and
replacement of the affected main rotor
blades.
Discussion of Final Airworthiness
Directive
Comments
The FAA received no comments on
the NPRM or on the determination of
the costs.
Conclusion
These helicopters have been approved
by the aviation authority of Germany
and are approved for operation in the
United States. Pursuant to the FAA’s
bilateral agreement with Germany (now
a member of the European Union),
Luftfahrt-Bundesamt, its technical
representative, has notified the FAA of
the unsafe condition described in its
AD. The FAA reviewed the relevant
data and determined that air safety
requires adopting this AD as proposed.
Accordingly, the FAA is issuing this AD
to address the unsafe condition on these
helicopters. Except for minor editorial
changes, this AD is adopted as proposed
in the NPRM.
Related Service Information Under 1
CFR Part 51
The FAA reviewed Eurocopter Alert
Service Bulletin No. ASB–MBB–BK117–
10–125, dated February 14, 2005. This
service information specifies procedures
for an inspection (for cracking of the
paint) and log card review (for a certain
entry or equivalent) to determine if any
bolted main rotor blades (i.e., main rotor
blades with bolted lead inner weights)
are installed, and replacement of the
affected main rotor blades.
This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section.
Costs of Compliance
The FAA estimates that this AD
affects 44 helicopters of U.S. Registry.
Labor rates are estimated at $85 per
work-hour. Based on these numbers, the
FAA estimates the following costs to
comply with this AD.

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 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 777-200/-200LR/-300/-300ER series
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 Feature
The Boeing Model 777-200/-200LR/-300/-300ER series airplanes will
incorporate the following novel or unusual design feature:
A digital systems architecture for the installation of a system
with wireless network and hosted application functionality that allows
access, from sources internal to the airplane, to the airplane's
internal electronic components.
Discussion
The digital systems architecture for the installation of an
Avionica avWIFI system with wireless network and hosted application
functionality on these Boeing Model 777 airplanes is a novel or unusual
design feature for transport category airplanes because it is composed
of several connected networks. This proposed network architecture is
used for a diverse set of airplane functions, including:
Flight-safety related control and navigation systems,
airline business and administrative support, and
passenger entertainment.
The airplane control domain and airline information-services domain
of these networks perform functions required for the safe operation and
maintenance of the airplane. Previously, these domains had very limited
connectivity with other network sources. This network architecture
creates a potential for unauthorized persons to access the aircraft
control domain and airline information-services domain from sources
internal to the airplane, and presents security vulnerabilities related
to the introduction of computer viruses and worms, user errors, and
intentional sabotage of airplane electronic assets (networks, systems,
and databases) critical to the safety and maintenance of the airplane.
The existing FAA regulations did not anticipate these networked
airplane system architectures. Furthermore, these regulations and the
current guidance material do not address potential security
vulnerabilities, which could be exploited by unauthorized access to
airplane networks, data buses, and servers. Therefore, these special
conditions ensure that the security (i.e., confidentiality, integrity,
and availability) of airplane systems will not be compromised by
unauthorized wired or wireless electronic connections from within the
airplane. These special conditions also require the applicant to
provide appropriate instructions to the operator to maintain all
electronic-system safeguards that have been implemented as part of the
original network design so that this feature does not allow or
reintroduce security threats.
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 777-200/-200LR/-300/-300ER series airplanes. Should
Archeion apply at a later date for a supplemental type certificate to
modify any other model included on Type Certificate No. T00001SE to
incorporate 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 Boeing Model 777-200/-200LR/-300/-300ER series airplanes. It is not
a rule of general applicability and affects only the applicant.
List of Subjects in 14 CFR Part 25

requirements.
Authority Citation
The authority citation for these special conditions is as follows:
Authority: 49 U.S.C. 106(f), 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 777-200/-200LR/-300/-
300ER series airplanes, as modified by Archeion Holdings, LLC, for
airplane electronic-system security protection from unauthorized
internal access.
(a) 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.
(b) The applicant must establish appropriate procedures to allow
the operator to ensure that continued airworthiness of the aircraft is
maintained, including all post type certification modifications that
may have an impact on the approved electronic-system security
safeguards.
