ACTION: Final special conditions; request
for comments.
AGENCY:
These special conditions are
issued for the Bombardier Inc.
(Bombardier), Model BD–700–2A12 and
BD–700–2A13 series airplanes. This
airplane will have a novel or unusual
design feature when compared to the
state of technology envisioned in the
applicable airworthiness standards for
transport-category airplanes. This
design feature is the fly-by-wire
electronic flight-control system (EFCS)
that will limit pitch and roll functions
to prevent the airplane from attaining
certain pitch attitudes and roll angles.
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
substance of these special conditions
has been published in the Federal

has determined that prior public notice
and comment are unnecessary, and
finds that, for the same reason, good
cause exists for adopting these special
conditions upon publication in the
Federal Register.

Background
On May 30, 2012, Bombardier applied
for an amendment to Type Certificate
No. T00003NY to include the new
Models BD–700–2A12 and BD–700–
2A13 series airplanes. The BD–700–
2A12 and BD–700–2A13 series
airplanes, are derivatives of the BD–700
currently approved under Type
Certificate No. T00003NY, and are
business jets with a maximum certified
passenger capacity of 19. The maximum
takeoff weight of Model BD–700–2A12
airplane is 106,250 lbs. and 104,800 lbs.
for the Model BD–700–2A13 airplane.
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 Bombardier Model BD–
700–2A12 and BD–700–2A13 series
airplanes must comply with the fuelvent and exhaust-emission requirements
of 14 CFR part 34, and the noisecertification 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 Features
The Model BD–700–2A12 and BD–
700–2A13 airplanes will incorporate the
E:\FR\FM\21MRR1.SGM
21MRR1
12252
Federal Register / Vol. 83, No. 55 / Wednesday, March 21, 2018 / Rules and Regulations
following novel or unusual design
features:
Fly-by-wire EFCS that will limit pitch
and roll functions to prevent the
airplane from attaining certain pitch
attitudes and roll angles greater than
plus or minus 65 degrees, and introduce
positive spiral stability introduced for
roll angles greater than 30 degrees at
speeds below VMO/MMO. This system
generates the actual surface commands
that provide for stability augmentation
and flight control for all three airplane
axes (longitudinal, lateral, and
directional).
Discussion
Part 25 of title 14 of the CFR does not
specifically relate to flight
characteristics associated with fixed
attitude limits. Bombardier proposes to
implement on the airplanes pitch and
roll attitude-limiting functions via the
EFCS normal mode. This will prevent
the airplane from attaining certain pitch
attitudes and roll angles greater than
plus or minus 65 degrees. In addition,
positive spiral stability, introduced for
roll angles greater than 30 degrees at
speeds below VMO/MMO, and spiral
stability characteristics, must not
require excessive pilot strength to
achieve bank angles up to the bankangle limit. These special conditions are
in addition to the requirements of
§ 25.143. 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 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 that model as well.
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 Bombardier Model
BD–700–2A12 and BD–700–2A13 series
airplanes:
In addition to § 25.143, the following
requirements apply to the electronic
flight-control system (EFCS) pitch- and
roll-limiting functions:
1. The pitch-limiting function must
not impede normal maneuvering for
pitch angles up to the maximum
required for normal maneuvering,
including a normal, all-enginesoperating takeoff, plus a suitable margin
to allow for satisfactory speed control.
2. The pitch- and roll-limiting
functions must not restrict or prevent
attaining pitch attitudes necessary for
emergency maneuvering, or roll angles
up to 65 degrees. Spiral stability, which
is introduced above 30 degrees of roll
angle, must not require excessive pilot
strength to achieve these roll angles.
Other protections, which further limit
the roll capability under certain extreme
angle-of-attack, attitude, or high-speed
conditions, are acceptable, as long as
they allow at least 45 degrees of roll
capability.
3. A lower limit of roll is acceptable
beyond the overspeed warning if it is
possible to recover the airplane to the
normal flight envelope without undue
difficulty or delay.

On May 30, 2012, Bombardier applied for an amendment to Type
Certificate No. T00003NY to include the new Models BD-700-2A12 and BD-
700-2A13 series airplanes. The BD-700-2A12 and BD-700-2A13 series

BD-700-2A12 airplane is 106,250 lbs. and 104,800 lbs. for the Model BD-

If the Administrator finds that the applicable airworthiness

the same type certificate be modified to incorporate the same novel or

the other model under Sec. 21.101.
In addition to the applicable airworthiness regulations and special
conditions, the Bombardier Model BD-700-2A12 and BD-700-2A13 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 Features
The Model BD-700-2A12 and BD-700-2A13 airplanes will incorporate
the
[[Page 12252]]
following novel or unusual design features:
Fly-by-wire EFCS that will limit pitch and roll functions to
prevent the airplane from attaining certain pitch attitudes and roll
angles greater than plus or minus 65 degrees, and introduce positive
spiral stability introduced for roll angles greater than 30 degrees at
speeds below VMO/MMO. This system generates the
actual surface commands that provide for stability augmentation and
flight control for all three airplane axes (longitudinal, lateral, and

a later date for a change to the type certificate to include another
model incorporating the same novel or unusual design feature, these

Conclusion
This action affects only certain novel or unusual design features
on one model series of airplanes. It is not a rule of general
applicability.
