ACTION:
Final special conditions.
These special conditions are
issued for the Bombardier Inc.
(Bombardier) Model BD–700–2A12 and
BD–700–2A13 airplanes. These
airplanes 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 feature is an
aluminum-lithium fuselage construction
that may provide different levels of
protection from post-crash fire threats
than would similar airplanes
constructed from traditional aluminum
structure. 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.

Jkt 241001
Background
On May 30, 2012, Bombardier applied
for an amendment to type certificate no.
T00003NY to include the new Model
BD–700–2A12 and BD–700–2A13
airplanes. These airplanes are
derivatives of the Model BD–700 series
of airplanes and are marketed as the
Bombardier Global 7000 (Model BD–
700–2A12) and Global 8000 (Model BD–
700–2A13). These airplanes are twinengine, transport-category, executiveinterior business jets. The maximum
passenger capacity is 19 and the
maximum takeoff weights are 106,250
lbs. (Model BD–700–2A12) and 104,800
lbs. (Model BD–700–2A13).
Type Certification Basis
Under the provisions of Title 14, Code
of Federal Regulations (14 CFR) 21.101,
Bombardier must show that the Model
BD–700–2A12 and BD–700–2A13
airplanes meet the applicable provisions
of the regulations listed in Type
Certificate No. T00003NY, 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 Model BD–700–2A12 and BD–
700–2A13 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 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 § 21.101.
In addition to the applicable
airworthiness regulations and special
conditions, the Model BD–700–2A12
and BD–700–2A13 airplanes must
comply with the fuel-vent and exhaustemission 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
PO 00000
Frm 00001
Fmt 4700
Sfmt 4700
with § 11.38, and they become part of
the type-certification basis under
§ 21.101.
Novel or Unusual Design Feature
Bombardier Inc. Model BD–700–2A12
and BD–700–2A13 airplanes will
incorporate the following novel or
unusual design feature: The fuselage
will be fabricated using aluminumlithium alloy materials instead of
conventional aluminum.
Discussion
The certification basis for the
Bombardier Model BD–700–2A12 and
BD–700–2A11 airplanes does not
include the burn through requirements
defined in § 25.856(b) because both
airplane models have a passenger
capacity of fewer than 20. The Model
BD–700–2A12 and BD–700–2A13
airplanes are introducing a new material
other than what has traditionally been
shown to be survivable from a ‘‘toxic’’
standpoint. The applicant must ensure
that the material being installed on an
airplane does not introduce a new
hazard that would reduce the
survivability of the passengers during a
post-crash situation, or that would
provide levels of toxic fumes that would
be lethal or incapacitating, thus
preventing evacuation of the airplane in
a crash scenario.
In accordance with § 21.16, fuselage
structure that includes aluminumlithium construction is an unusual
design feature for large, transportcategory airplanes certificated under 14
CFR part 25.
Regulations applicable to burn
requirements, including §§ 25.853 and
25.856(a), remain valid for these
airplanes, but do not protect against the
threat generated from potentially toxic
levels of gases produced from
aluminum-lithium alloy materials.
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.
Discussion of Comments
Notice of Proposed Special
Conditions No. 25–16–07–SC for the
Bombardier Model BD–700–2A12 and
BD–700–2A13 airplanes was published
in the Federal Register on October 26,
2016 (81 FR 74347). One comment was
received.

Federal Register / Vol. 82, No. 149 / Friday, August 4, 2017 / Rules and Regulations
The commenter acknowledged that
the use of the aluminum-lithium alloy
would require full certification to the
existing regulations. However, they
contend that the material is not novel
and unusual and does not require
special conditions.
The FAA does not agree. While it is
true that, with the level of lithium in the
alloys presently tested, the proposed
aluminum-lithium alloy does not appear
to pose a significant risk, the existing
regulations, as discussed above, do not
adequately address the use of this
specific alloy technology. Lithium metal
is highly flammable and toxic; therefore,
the FAA is concerned about the use of
lithium in aircraft alloys. The FAA did
not have data on the properties of
aluminum-lithium when exposed to a
post-crash fire threat prior to applying
these special conditions.
Therefore, special conditions are
required until the regulations are
amended to provide sufficient
requirements for the application of this
new alloy technology.
Applicability
As discussed above, these special
conditions are applicable to the
Bombardier Model BD–700–2A12 and
BD–700–2A13 airplanes. Should
Bombardier 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 the
other model as well.
Conclusion
This action affects only one novel or
unusual design feature on Bombardier
Model BD–700–2A12 and BD–700–
2A13 airplanes. It is not a rule of general
applicabilit.

AGENCY:
These special conditions are
issued for the Embraer S.A. (Embraer)
Model ERJ 190–300 airplane. This
airplane will have a novel or unusual
design feature when compared to the
state of technology envisioned in the

involves flight-envelope protection
functions that limit such flight
parameters as, for example, angle of
attack, normal load factor, attitude, bank
angle, and speed during normal
operation. 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

SUPPLEMENTARY INFORMATION: The
substance of these special conditions
has been subject 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.
In addition, since 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 finds it unnecessary to delay the
effective date and finds that good cause
exists for adopting these special
conditions upon publication in the
Federal Register.

SUPPLEMENTARY INFORMATION:
Background
On May 30, 2012, Bombardier applied for an amendment to type
certificate no. T00003NY to include the new Model BD-700-2A12 and BD-
700-2A13 airplanes. These airplanes are derivatives of the Model BD-700

takeoff weights are 106,250 lbs. (Model BD-700-2A12) and 104,800 lbs.
(Model BD-700-2A13).
Type Certification Basis
Under the provisions of Title 14, Code of Federal Regulations (14
CFR) 21.101, Bombardier must show that the Model BD-700-2A12 and BD-
700-2A13 airplanes meet the applicable provisions of the regulations
listed in Type Certificate No. T00003NY, 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 Model BD-700-2A12 and BD-700-2A13
airplanes because of a novel or unusual design feature, special

the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the Model 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.
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
Bombardier Inc. Model BD-700-2A12 and BD-700-2A13 airplanes will
incorporate the following novel or unusual design feature: The fuselage
will be fabricated using aluminum-lithium alloy materials instead of
conventional aluminum.
Discussion
The certification basis for the Bombardier Model BD-700-2A12 and

scenario.
In accordance with Sec. 21.16, fuselage structure that includes
aluminum-lithium construction is an unusual design feature for large,
transport-category airplanes certificated under 14 CFR part 25.
Regulations applicable to burn requirements, including Sec. Sec.
25.853 and 25.856(a), remain valid for these airplanes, but do not
protect against the threat generated from potentially toxic levels of
gases produced from aluminum-lithium alloy materials.
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.
Discussion of Comments
Notice of Proposed Special Conditions No. 25-16-07-SC for the
Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes was published in
the Federal Register on October 26, 2016 (81 FR 74347). One comment was
received.
[[Page 36320]]
The commenter acknowledged that the use of the aluminum-lithium
alloy would require full certification to the existing regulations.
However, they contend that the material is not novel and unusual and
does not require special conditions.
The FAA does not agree. While it is true that, with the level of

Therefore, special conditions are required until the regulations
are amended to provide sufficient requirements for the application of
this new alloy technology.
Applicability
As discussed above, these special conditions are applicable to the
Bombardier Model BD-700-2A12 and BD-700-2A13 airplanes. Should
Bombardier apply at a later date for a change to the type certificate
to include another model incorporating the same novel or unusual design
