Discussion
The FAA is adopting a new
airworthiness directive (AD) for certain
Bombardier, Inc., Model BD–700–1A10
and BD–700–1A11 airplanes. This AD
was prompted by a report that cracking
was discovered in a channel within a
structural support member for the
rudder quadrant, rudder feel unit
assembly, and environmental control
system due to fatigue. This AD requires
repetitive inspections of the rudder
quadrant box assembly for any cracking,
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2019–11, dated March 22, 2019 (also
referred to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc., Model BD–
700–1A10 and BD–700–1A11 airplanes.

Federal Register / Vol. 85, No. 64 / Thursday, April 2, 2020 / Rules and Regulations
and locating Docket No. FAA–2019–
0876.
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Bombardier, Inc., Model
BD–700–1A10 and BD–700–1A11
airplanes. The NPRM published in the
Federal Register on December 16, 2019
(84 FR 68370). The NPRM was
prompted by a report that cracking was
discovered in a channel within a
structural support member for the
rudder quadrant, rudder feel unit
assembly, and environmental control
system due to fatigue. The NPRM
proposed to require repetitive
inspections of the rudder quadrant box
assembly for any cracking, and
modification of the rudder quadrant box
assembly. The FAA is issuing this AD
to address cracking in the rudder
quadrant support structure, which can
lead to progressive deterioration in the
performance of the systems it supports,
and could eventually lead to
uncommanded rudder movement and
bleed air leakage. See the MCAI for
additional background information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The FAA received no
comments on the NPRM or on the
determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data
and determined that air safety and the
public interest require adopting this
final rule as proposed, except for minor
editorial changes. The FAA has
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM for
addressing the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.

SUPPLEMENTARY INFORMATION:
Discussion
The ANAC, which is the aviation
authority for Brazil, has issued Brazilian
AD 2019–06–01, effective June 17, 2019
(‘‘Brazilian AD 2019–06–01’’) (also
referred to as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Embraer S.A. Model ERJ 190–
100 STD, –100 LR, –100 IGW, –100 SR,
–200 STD, –200 LR, and –200 IGW
airplanes. (Model ERJ 190–100 SR
airplanes are not certified by the FAA
and are not included on the U.S. type
certificate data sheet; this AD therefore
does not include those airplanes in the
applicability.)
The FAA issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Embraer S.A. Model ERJ
190–100 STD, –100 LR, –100 IGW, –200
STD, –200 LR, and –200 IGW airplanes.
The NPRM published in the Federal
Register on September 30, 2019 (84 FR
51469). The NPRM was prompted by
reports of structural cracks in the wing
lower skin stringers on both half wings.
The NPRM proposed to require
repetitive inspections for cracking and
fuel leakage of the lower skin stringers
on both half wings, and applicable
related investigative and corrective
actions.
The FAA is issuing this AD to address
structural cracks in the wing lower skin,
which could result in fuel leakage and
reduced structural integrity of the wing.
See the MCAI for additional background
information.
Comments
The FAA gave the public the
opportunity to participate in developing
this final rule. The following presents
the comments received on the NPRM
and the FAA’s response to each
comment.
Request To Revise Applicability

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2019-11, dated March
22, 2019 (also referred to as the Mandatory Continuing Airworthiness
Information, or ``the MCAI''), to correct an unsafe condition for
certain Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes.
You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for
[[Page 18432]]
and locating Docket No. FAA-2019-0876.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 by adding an AD that would apply to certain Bombardier,
Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published
in the Federal Register on December 16, 2019 (84 FR 68370). The NPRM
was prompted by a report that cracking was discovered in a channel
within a structural support member for the rudder quadrant, rudder feel
unit assembly, and environmental control system due to fatigue. The
NPRM proposed to require repetitive inspections of the rudder quadrant
box assembly for any cracking, and modification of the rudder quadrant
box assembly. The FAA is issuing this AD to address cracking in the
rudder quadrant support structure, which can lead to progressive
deterioration in the performance of the systems it supports, and could
eventually lead to uncommanded rudder movement and bleed air leakage.
See the MCAI for additional background information.
Comments
The FAA gave the public the opportunity to participate in
developing this final rule. The FAA received no comments on the NPRM or
on the determination of the cost to the public.
Conclusion
The FAA reviewed the relevant data and determined that air safety
and the public interest require adopting this final rule as proposed,
except for minor editorial changes. The FAA has determined that these
minor changes:
Are consistent with the intent that was proposed in the
NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. Subtitle VII: Aviation Programs,
describes in more detail the scope of the Agency's authority.
The FAA issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
This AD will not have federalism implications under Executive Order
13132. This AD will not have a
[[Page 18433]]
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
