Federal Register / Vol. 80, No. 152 / Friday, August 7, 2015 / Rules and Regulations
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 or similar novel
or unusual design feature, the special
conditions would also apply to the other
model under § 21.101.
In addition to the applicable
airworthiness regulations and special
conditions, the BD–700–2A12 and BD–
700–2A13 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, and the FAA must issue a
finding of regulatory adequacy under
§ 611 of Public Law 92–574, the ‘‘Noise
Control Act of 1972.’’
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
§ 21.17(a)(2).
Novel or Unusual Design Feature
The BD–700–2A12 and BD–700–2A13
airplanes will incorporate the following
novel or unusual design feature: Side
stick controllers for pitch and roll
control, which are not mechanically
interconnected as with conventional
wheel and column controls. These
airplanes also have a fly-by-wire
electronic flight control system. This
system provides an electronic interface
between the pilot’s flight controls and
the flight control surfaces for both
normal and failure states, and it
generates the actual surface commands
that provide for stability augmentation
and control about all three airplane
axes. In addition, pilot control authority
may be uncertain, because the side
sticks are not mechanically
interconnected as with conventional
wheel and column controls.

Discussion
Current FAA regulations do not
specifically address the use of side stick
controllers for pitch and roll control.
The unique features of the side stick
must therefore be demonstrated through
flight and simulator tests to have
suitable handling and control
characteristics when considering the
following:
1. The handling qualities tasks/
requirements of the BD–700–2A12 and
BD–700–2A13 airplanes special
conditions and other part 25 stability,
control, and maneuverability
requirements, including the effects of
turbulence.
2. General ergonomics: Arm rest
comfort and support, local freedom of

movement, displacement angle
suitability, and axis harmony.
3. Inadvertent input in turbulence.
4. Inadvertent pitch-roll cross talk.
These special conditions elaborate on
these requirements and 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.
The FAA Handling Qualities Rating
Method (HQRM) in appendix 5 of
Advisory Circular 25–7C, ‘‘Flight Test
Guide for Certification of Transport
Category Airplanes,’’ may be used to
show compliance.
Applicability
As discussed above, these special
conditions are applicable to the
Bombardier Inc. Models BD–700–2A12
and BD–700–2A13 series airplanes.
Should Bombardier Inc. 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 certain novel
or unusual design features on two
model series of airplanes. 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, the FAA
has determined that prior public notice
and comment are unnecessary, 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.

25.175(d), Bombardier must show that
the temporary and maximum prolonged
force levels for the side stick controllers
are suitable for all expected operating
conditions and configurations, whether
normal or non-normal.
2. Pilot control authority: The
electronic side stick controller coupling
design must provide for corrective and/
or overriding control inputs by either
pilot with no unsafe characteristics.
Annunciation of the controller status
must be provided and must not be
confusing to the flightcrew.
3. Pilot control: Bombardier must
show by flight tests that the use of side
stick controllers does not produce
unsuitable pilot-in-the-loop control
characteristics when considering
precision path control/tasks and
turbulence. In addition, pitch and roll
control force and displacement
sensitivity must be compatible, so that
normal inputs on one control axis will
not cause significant unintentional
inputs on the other.

Background
Bombardier Inc. located in Montreal,
Canada, applied to Transport Canada
Civil Aviation (TCCA) on January 7,
2012, and May 30, 2012, for two
amended type certificates in the
transport airplane category for two new
airplane models designated as the BD–
700–2A12 and BD–700–2A13. These
airplanes are 19-passenger, twin-engine,
ultra long-range large airplanes targeting
the executive interior business jet
market. They share an identical supplier
base and significant common design
elements including a fly-by-wire
electronic flight control system (EFCS).
Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.17,
Bombardier Inc. must show that the BD–
700–2A12 and BD–700–2A13 airplanes
meet the applicable provisions of 14
CFR part 25 as amended by
Amendments 25–1 through 25–138
except for Amendment 25–137.
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 BD–700–2A12 and BD–700–
2A13 airplanes because of a novel or
PO 00000

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 type certificate
for that model be amended later to
include any other model that
incorporates the same or similar novel
or unusual design features, these special
conditions would also apply to the other
model under § 21.101.
In addition to the applicable
airworthiness regulations and special
conditions, the BD–700–2A12 and BD–
700–2A13 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, and the FAA must issue a
finding of regulatory adequacy under
§ 611 of Public Law 92–574, the ‘‘Noise
Control Act of 1972.’’
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
§ 21.17(a)(2).
Novel or Unusual Design Features
The BD–700–2A12 and BD–700–2A13
airplanes will incorporate the following
novel or unusual design features: A flyby-wire EFCS and no direct coupling
from the flight deck controller to the
control surface. As a result, the pilot is
not aware of the actual control surface
position as envisioned under current
airworthiness standards.
Discussion
These special conditions require that
the flightcrew receive a suitable flight
control position annunciation when a
flight condition exists in which nearly
full surface authority (not crewcommanded) is being used. Suitability
of such a display must take into account
that some pilot-demanded maneuvers
(e.g., rapid roll) are necessarily
associated with intended full
performance, which may saturate the
surface. Therefore, simple alerting
systems function in both intended and
unexpected control-limiting situations.
As a result, they must be properly
balanced between providing necessary
crew awareness and being a potential
nuisance to the flightcrew. A monitoring
system that compares airplane motion
and surface deflection with the demand
of the pilot side-stick controller could
help reduce nuisance alerting.
These special conditions also address
flight control system mode
annunciation. Suitable mode
annunciation must be provided to the
flightcrew for events that significantly
change the operating mode of the

system but do not merit the classic
‘‘failure warning.’’
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
Bombardier Models BD–700–2A12 and
BD–700–2A13 series airplanes. Should
Bombardier Inc. apply at a later date for
a change to the type certificate to
include another model incorporating the
same novel or unusual design features,
these special conditions would apply to
that model as well.
Conclusion
This action affects only certain novel
or unusual design features on two
model series of airplanes. 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, the FAA
has determined that prior public notice

cause exists for adopting these special
conditions upon publication in the
Federal Register. The FAA is requesting
comments to allow interested persons to

opportunities for comment described
above.

ACTION: Final rule.
AGENCY:
This final rule amends the
Export Administration Regulations
(EAR) to further implement U.S.
sanctions on certain Russian energy
projects. Specifically, in this rule, the
Bureau of Industry and Security (BIS)
amends the EAR by adding a Russian oil
and gas field, the Yuzhno-Kirinskoye
Field located in the Sea of Okhotsk, to
the Entity List. This Russian field is
reported to contain substantial reserves
of oil in addition to reserves of gas. The
U.S. Government has determined,
therefore, that exports, reexports, and
transfers (in-country) of all items subject
to the EAR to this Russian field by any
person without first obtaining a BIS
license present an unacceptable risk of
use in, or diversion to, the activities
specified in the Russian industry sector
sanctions. Thus, as part of the BIS ‘‘is
informed’’ process, this final rule adds
this Russian field to the Entity List to
further implement the Russian industry
sector sanctions. This Russian field will
be listed on the Entity List under the
destination of Russia. This final rule
clarifies the introductory text of the
Entity List to specify that the embargoes
and other special controls part of the
EAR is also used to add entities to the

Entity List. Lastly, this final rule makes
a change to the Russian industry sector
sanctions by clarifying the additional
prohibition on those informed by BIS
also includes end-uses that are within
the scope of the Russian Industry sector
sanctions.
DATES: This rule is effective August 7,
2015.

Background
Bombardier Inc. located in Montreal, Canada, applied to Transport
Canada Civil Aviation (TCCA) on January 7, 2012, and May 30, 2012, for
two amended type certificates in the transport airplane category for
two new airplane models designated as the BD-700-2A12 and BD-700-2A13.
These airplanes are 19-passenger, twin-engine, ultra long-range large

2A13 airplanes meet the applicable provisions of 14 CFR part 25 as
amended by Amendments 25-1 through 25-138 except for Amendment 25-137.
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 BD-700-2A12 and BD-700-2A13
airplanes because of a novel or unusual design feature, special

apply to the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the BD-700-2A12 and BD-700-2A13 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, and 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, 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 BD-700-2A12 and BD-700-2A13 airplanes will incorporate the
following novel or unusual design features: A fly-by-wire EFCS and no
direct coupling from the flight deck controller to the control surface.
As a result, the pilot is not aware of the actual control surface
position as envisioned under current airworthiness standards.
Discussion
These special conditions require that the flightcrew receive a
suitable flight control position annunciation when a flight condition
exists in which nearly full surface authority (not crew-commanded) is
being used. Suitability of such a display must take into account that
some pilot-demanded maneuvers (e.g., rapid roll) are necessarily
associated with intended full performance, which may saturate the
surface. Therefore, simple alerting systems function in both intended
and unexpected control-limiting situations. As a result, they must be
properly balanced between providing necessary crew awareness and being
a potential nuisance to the flightcrew. A monitoring system that
compares airplane motion and surface deflection with the demand of the
pilot side-stick controller could help reduce nuisance alerting.
These special conditions also address flight control system mode
annunciation. Suitable mode annunciation must be provided to the
flightcrew for events that significantly change the operating mode of
the
[[Page 47402]]
system but do not merit the classic ``failure warning.''
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
Bombardier Models BD-700-2A12 and BD-700-2A13 series airplanes. Should
Bombardier Inc. apply at a later date for a change to the type
certificate to include another model incorporating the same novel or
unusual design features, these special conditions would apply to that
model as well.
Conclusion
This action affects only certain novel or unusual design features
on two model series of airplanes. 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, the FAA has determined
that prior public notice and comment are unnecessary, 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
0
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 the Bombardier Inc. Models BD-700-2A12
and BD-700-2A13 series airplanes.
1. In addition to the requirements of Sec. Sec. 25.143, 25.671,
and 25.672, the following requirements apply:
a. The system design must ensure that the flightcrew is made
suitably aware whenever the primary control means nears the limit of
control authority.
Note: The term ``suitably aware'' indicates annunciations provided
to the flightcrew are appropriately balanced between nuisance and that
necessary for crew awareness.
b. If the design of the flight control system has multiple modes of
operation, a means must be provided to indicate to the flightcrew any
mode that significantly changes or degrades the normal handling or
operational characteristics of the airplane.
Issued in Renton, Washington, on June 17, 2015.
