SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016–11–02,
Amendment 39–18529 (81 FR 33371,
May 26, 2016) (‘‘AD 2016–11–02’’). AD
2016–11–02 applied to all Bombardier,
Inc., Model CL–600–2C10 (Regional Jet
Series 700, 701, & 702) airplanes; Model
CL–600–2D15 (Regional Jet Series 705)
airplanes; Model CL–600–2D24
(Regional Jet Series 900) airplanes; and
Model CL–600–2E25 (Regional Jet Series
1000) airplanes. The NPRM published
in the Federal Register on June 12, 2017
(82 FR 26864). The NPRM was
prompted by reports of loose or missing
fasteners and collars on the upper and
lower engine pylon structure common
to the upper and lower pylon skin
panels and engine thrust fitting. The
NPRM proposed to continue to require
the repetitive inspections of the upper
and lower engine pylons for protruding,
loose, or missing fasteners; and repair if
necessary. The NPRM also proposed to
require replacement of affected
fasteners, which terminates the
inspections. We are issuing this AD to
prevent protruding, loose, or missing
fasteners, which could result in
structural failure of the engine pylons.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
E:\FR\FM\24MYR1.SGM
24MYR1
Federal Register / Vol. 83, No. 101 / Thursday, May 24, 2018 / Rules and Regulations
for Canada, has issued Canadian
Airworthiness Directive CF–2016–10R1,
dated July 8, 2016 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for all Bombardier, Inc., Model CL–600–
2C10 (Regional Jet Series 700, 701, &
702) airplanes; Model CL–600–2D15
(Regional Jet Series 705) airplanes;
Model CL–600–2D24 (Regional Jet
Series 900) airplanes; and Model CL–
600–2E25 (Regional Jet Series 1000)
airplanes. The MCAI states:
There have been several reported findings
of loose or missing Hi-Lite fasteners and
collars on the left hand (L/H) and right hand
(R/H) upper and lower engine pylon
structure common to the upper and lower
pylon skin panels and engine thrust fitting.
Missing fasteners in these areas are shown to
significantly reduce the safety margins and
could result in a structural failure of the
engine pylon.
Bombardier, as an interim corrective action
issued a new Aircraft Maintenance Manual
(AMM) task for detailed inspection of the
engine pylon rib and skin fasteners to inspect
for protruding, loose or missing fasteners and
rectify any discrepancies noted in accordance
with a Repair Engineering Order (REO). The
original version of this [Canadian] AD, CF–
2016–10, mandated the subject inspection
and necessary rectification.
Bombardier has since issued Service
Bulletin (SB) 670BA–54–007 to replace all
affected fasteners with interference fit
fasteners [including applicable related
investigative and corrective actions], as
terminating action for the mandated
inspection requirement. [Canadian] AD CF–
2016–10 is now being revised to mandate
compliance with SB 670BA–54–007.

Related investigative actions include
measurements of the attach holes in the
engine pylon upper structure and
special detailed visual inspections for
cracks in the engine pylon structure.
Corrective actions include repair. You

Comments
We gave the public the opportunity to
participate in developing this AD. The
following presents the comments
received on the NPRM and the FAA’s
response to each comment.
Request To Include Additional Service
Information in Credit Paragraph
Mesa Airlines suggested that
Bombardier Service Bulletin 670BA–54–
VerDate Sep<11>2014
18:07 May 23, 2018
Jkt 244001
007, dated May 13, 2016, be included in
paragraph (l), ‘‘Credit for Previous
Actions,’’ of the proposed AD. The
commenter did not provide justification
for its request. We infer that the
commenter made this request to provide
credit for operators that completed the
actions in Bombardier Service Bulletin
670BA–54–007, dated May 13, 2016,
prior to the effective date of the
proposed AD.
We do not agree that the commenter’s
requested change is needed. Paragraph
(f) of this AD states that the actions
specified in this AD must be
accomplished ‘‘unless already done.’’
The phrase ‘‘unless already done’’
provides credit for accomplishment of
the actions required by paragraph (j) of
this AD, if done in accordance with the
Accomplishment Instructions of
Bombardier Service Bulletin 670BA–54–
007, dated May 13, 2016, prior to the
effective date of this AD. Therefore, we
have not changed this AD in this regard.
Request To Revise Paragraph (g) of the
Proposed AD To Require Airplane
Maintenance Manual Task
Bombardier requested that Task 54–
51–01–220–801, ‘‘Detailed Inspection of
the Engine Pylon Rib and Skin
Fasteners,’’ to Chapter 54, ‘‘Nacelle/
Pylons,’’ to Part 2 of the Bombardier
CRJ700/900/1000 Aircraft Maintenance
Manual (AMM), be required by
paragraph (g) of the proposed AD in lieu
of Bombardier Temporary Revision (TR)
54–0007, dated March 8, 2016, to the
CRJ700/900/1000 AMM. The
commenter stated that Bombardier TR
54–0007 was incorporated into Revision
52 of the Bombardier CRJ700/900/1000
AMM, and that the AMM is currently at
Revision 56.
We partially agree with the
commenter’s request. We agree to
include Task 54–51–01–220–801,
‘‘Detailed Inspection of the Engine
Pylon Rib and Skin Fasteners,’’ to
Chapter 54, ‘‘Nacelle/Pylons,’’ to Part 2
of the Bombardier CRJ700/900/1000
AMM as a method of compliance in
paragraph (g) of this AD, but we do not
agree to remove Bombardier TR 54–
0007, dated March 8, 2016, to the
Bombardier CRJ700/900/1000 AMM. We
have revised paragraph (g) of this AD to
include both Task 54–51–01–220–801,
‘‘Detailed Inspection of the Engine
Pylon Rib and Skin Fasteners,’’ to
Chapter 54, ‘‘Nacelle/Pylons,’’ to Part 2
of the Bombardier CRJ700/900/1000
AMM, CSP B–001, Revision 56, dated
September 25, 2017; and Bombardier TR
54–0007, dated March 8, 2016. This
revision provides operators with an
option to use either service document to
accomplish the required action.

Conclusion
We reviewed the available data,
including the comments received, and
determined that air safety and the
public interest require adopting this AD
with the changes described previously
and minor editorial changes. We have
determined that these changes:
• Are consistent with the intent that
was proposed in the NPRM for
correcting the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM.
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this AD.

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.
We are 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.
This AD is issued in accordance with
authority delegated by the Executive
Director, Aircraft Certification Service,
as authorized by FAA Order 8000.51C.
In accordance with that order, issuance
of ADs is normally a function of the
Compliance and Airworthiness
Division, but during this transition
period, the Executive Director has
delegated the authority to issue ADs
applicable to transport category
airplanes to the Director of the System
Oversight Division.
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. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

Discussion
We issued AD 2018–06–10,
Amendment 39–19230 (83 FR 13401,
March 29, 2018), (‘‘AD 2018–06–10’’),
for certain Honda Aircraft Company
LLC Model HA–420 airplanes. AD
2018–06–10 required incorporating a
temporary revision into the airplane
flight manual and replacing faulty
power brake valves upon condition. AD
2018–06–10 resulted from reports of
unannunciated asymmetric braking
during ground operations and landing
deceleration. We issued AD 2018–06–10
to detect failure of the power brake
valve. The unsafe condition, if not
addressed, could result in degraded
braking performance and reduced
directional control during ground
operations and landing deceleration.
Actions Since AD 2018–06–10 was
Issued
Since we issued AD 2018–06–10, we
were notified by Honda Aircraft
Company that Service Bulletin SB–420–
32–001, dated January 8, 2018, contains
a typographical error in the serial
number effectivity, which was also used
as the basis for the Applicability section
of AD 2018–06–10. The service bulletin
incorrectly listed the applicable Model
HA–420 airplane serial number
effectivity as 42000011 through 4200089
instead of 42000011 through 42000089.
We are issuing this AD to address the
unsafe condition on these products by
correcting the inadvertent serial number
error.
Related Service Information Under 1
CFR Part 51
We reviewed Honda Aircraft
Company Service Bulletin SB–420–32–
001, Revision B, dated April 16, 2018.
The service information describes
procedures for replacing a defective
PBV with an improved design PBV. 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.
FAA’s Determination
We are issuing this AD because we
evaluated all the relevant information
and determined the unsafe condition
described previously is likely to exist or
develop in other products of the same
type design.
AD Requirements
This AD requires inserting a
temporary revision into the AFM, which
may be performed by the owner/
operator (pilot) holding at least a private
pilot certificate and must be entered
into the airplane records showing

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2016-11-02, Amendment 39-18529 (81 FR 33371,
May 26, 2016) (``AD 2016-11-02''). AD 2016-11-02 applied to all
Bombardier, Inc., Model CL-600-2C10 (Regional Jet Series 700, 701, &
702) airplanes; Model CL-600-2D15 (Regional Jet Series 705) airplanes;
Model CL-600-2D24 (Regional Jet Series 900) airplanes; and Model CL-
600-2E25 (Regional Jet Series 1000) airplanes. The NPRM published in
the Federal Register on June 12, 2017 (82 FR 26864). The NPRM was
prompted by reports of loose or missing fasteners and collars on the
upper and lower engine pylon structure common to the upper and lower
pylon skin panels and engine thrust fitting. The NPRM proposed to
continue to require the repetitive inspections of the upper and lower
engine pylons for protruding, loose, or missing fasteners; and repair
if necessary. The NPRM also proposed to require replacement of affected
fasteners, which terminates the inspections. We are issuing this AD to
prevent protruding, loose, or missing fasteners, which could result in
structural failure of the engine pylons.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority
[[Page 24013]]
for Canada, has issued Canadian Airworthiness Directive CF-2016-10R1,
dated July 8, 2016 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for all Bombardier, Inc., Model CL-600-2C10 (Regional Jet
Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet
Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900)
airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes.
The MCAI states:
There have been several reported findings of loose or missing
Hi-Lite fasteners and collars on the left hand (L/H) and right hand
(R/H) upper and lower engine pylon structure common to the upper and
lower pylon skin panels and engine thrust fitting. Missing fasteners
in these areas are shown to significantly reduce the safety margins
and could result in a structural failure of the engine pylon.
Bombardier, as an interim corrective action issued a new
Aircraft Maintenance Manual (AMM) task for detailed inspection of
the engine pylon rib and skin fasteners to inspect for protruding,
loose or missing fasteners and rectify any discrepancies noted in
accordance with a Repair Engineering Order (REO). The original
version of this [Canadian] AD, CF-2016-10, mandated the subject
inspection and necessary rectification.
Bombardier has since issued Service Bulletin (SB) 670BA-54-007
to replace all affected fasteners with interference fit fasteners
[including applicable related investigative and corrective actions],
as terminating action for the mandated inspection requirement.
[Canadian] AD CF-2016-10 is now being revised to mandate compliance
with SB 670BA-54-007.
Related investigative actions include measurements of the attach
holes in the engine pylon upper structure and special detailed visual
inspections for cracks in the engine pylon structure. Corrective
actions include repair. You may examine the MCAI in the AD docket on
the internet at https://www.regulations.gov by searching for and
locating Docket No. FAA-2017-0530.
You may examine the MCAI in the AD docket on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA-2017-
0530.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM and
the FAA's response to each comment.
Request To Include Additional Service Information in Credit Paragraph
Mesa Airlines suggested that Bombardier Service Bulletin 670BA-54-
007, dated May 13, 2016, be included in paragraph (l), ``Credit for
Previous Actions,'' of the proposed AD. The commenter did not provide
justification for its request. We infer that the commenter made this
request to provide credit for operators that completed the actions in
Bombardier Service Bulletin 670BA-54-007, dated May 13, 2016, prior to
the effective date of the proposed AD.
We do not agree that the commenter's requested change is needed.
Paragraph (f) of this AD states that the actions specified in this AD
must be accomplished ``unless already done.'' The phrase ``unless
already done'' provides credit for accomplishment of the actions
required by paragraph (j) of this AD, if done in accordance with the
Accomplishment Instructions of Bombardier Service Bulletin 670BA-54-
007, dated May 13, 2016, prior to the effective date of this AD.
Therefore, we have not changed this AD in this regard.
Request To Revise Paragraph (g) of the Proposed AD To Require Airplane
Maintenance Manual Task
Bombardier requested that Task 54-51-01-220-801, ``Detailed
Inspection of the Engine Pylon Rib and Skin Fasteners,'' to Chapter 54,
``Nacelle/Pylons,'' to Part 2 of the Bombardier CRJ700/900/1000
Aircraft Maintenance Manual (AMM), be required by paragraph (g) of the
proposed AD in lieu of Bombardier Temporary Revision (TR) 54-0007,
dated March 8, 2016, to the CRJ700/900/1000 AMM. The commenter stated
that Bombardier TR 54-0007 was incorporated into Revision 52 of the
Bombardier CRJ700/900/1000 AMM, and that the AMM is currently at
Revision 56.
We partially agree with the commenter's request. We agree to
include Task 54-51-01-220-801, ``Detailed Inspection of the Engine
Pylon Rib and Skin Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to
Part 2 of the Bombardier CRJ700/900/1000 AMM as a method of compliance
in paragraph (g) of this AD, but we do not agree to remove Bombardier
TR 54-0007, dated March 8, 2016, to the Bombardier CRJ700/900/1000 AMM.
We have revised paragraph (g) of this AD to include both Task 54-51-01-
220-801, ``Detailed Inspection of the Engine Pylon Rib and Skin
Fasteners,'' to Chapter 54, ``Nacelle/Pylons,'' to Part 2 of the
Bombardier CRJ700/900/1000 AMM, CSP B-001, Revision 56, dated September
25, 2017; and Bombardier TR 54-0007, dated March 8, 2016. This revision
provides operators with an option to use either service document to
accomplish the required action.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously and minor editorial
changes. We have determined that these changes:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this AD.

Programs,'' describes in more detail the scope of the Agency's
authority.
We are 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.
This AD is issued in accordance with authority delegated by the
Executive Director, Aircraft Certification Service, as authorized by
FAA Order 8000.51C. In accordance with that order, issuance of ADs is
normally a function of the Compliance and Airworthiness Division, but
during this transition period, the Executive Director has delegated the
authority to issue ADs applicable to transport category airplanes to
the Director of the System Oversight Division.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a 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. Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
