SUPPLEMENTARY INFORMATION:

Discussion
We 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
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 July 6, 2018 (83 FR
31504). The NPRM was prompted by
reports of damage to the protective
coating and corrosion on the piston/axle
of the MLG, caused by friction between
the inboard axle sleeve and the axle
thrust face. The NPRM proposed to
require revising the maintenance or
inspection program, as applicable, to
incorporate a detailed inspection of the
MLG piston/axle for damage to the
protective coating and for corrosion.
We are issuing this AD to address
damage to the protective coating and
corrosion found on the piston/axle of
the MLG, caused by friction between the
VerDate Sep<11>2014
16:15 Nov 06, 2018
Jkt 247001
inboard axle sleeve and the axle thrust
face, which could cause the axle to
separate from the piston/axle, and
ultimately lead to collapse of the
landing gear during ground maneuvers
or upon landing.
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian AD
CF–2017–38, dated December 20, 2017
(referred to after this as the Mandatory
Continuing Airworthiness Information,
or ‘‘the MCAI’’), to correct an unsafe
condition for certain 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 reports of damage to the
protective coating and/or corrosion on the
piston/axle of the Main Landing Gear (MLG).
The damage to the protective coating was
caused by friction between the inboard axle
sleeve and the axle thrust face. If not
corrected, this condition can cause the axle
to separate from the piston/axle [and
consequent collapse of the landing gear
during ground maneuvers or upon landing].
This [Canadian] AD mandates the
incorporation of a new maintenance task in
order to perform a [detailed] visual
inspection of the piston/axle of the MLG to
prevent the axle separation from the piston/
axle.
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–2018–
0551.
Comments
We 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.
Support for the NPRM
The Air Line Pilots Association,
International and Endeavor Air stated
their support for the proposed AD.
Request To Refer to Certain Revised
Service Information
Endeavor Air noted that Bombardier,
Inc. has issued certain revised service
information and requested that the
proposed AD be updated to reference
the revised service information.
We agree with the commenter’s
request. We have determined the
revised service information should be
referenced in regards to calculating the
time since piston/axle entry into
service, since operators might have done
the latest inspection, restoration, or
repair using the revised service
PO 00000
Frm 00007
Fmt 4700
Sfmt 4700
55607
information. We have updated
paragraph (h) of this AD to refer to the
revised service information and
reorganized paragraph (h) of this AD for
consistency.
Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting this
final rule with the changes described
previously and minor editorial changes.
We have 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.
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of this final rule.
Related Service Information Under 1
CFR Part 51
Bombardier, Inc. has issued CRJ
Series Regional Jet Temporary Revision
(TR) MRB–0059, dated March 20, 2015.
The service information describes an
airworthiness limitation task for a
detailed inspection for damage to the
protective coating and for corrosion on
the piston/axle of the MLG. 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.
Costs of Compliance
We estimate that this AD affects 530
airplanes of U.S. registry. We estimate
the following costs to comply with this
AD:
We have determined that revising the
maintenance or inspection program
takes an average of 90 work-hours per
operator, although we recognize that
this number may vary from operator to
operator. In the past, we have estimated
that this action takes 1 work-hour per
airplane. Since operators incorporate
maintenance or inspection program
changes for their affected fleet(s), we
have determined that a per-operator
estimate is more accurate than a perairplane estimate. Therefore, we
estimate the total cost per operator to be
$7,650 (90 work-hours × $85 per workhour).
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
E:\FR\FM\07NOR1.SGM
07NOR1
55608
Federal Register / Vol. 83, No. 216 / Wednesday, November 7, 2018 / Rules and Regulations
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 and associated appliances to
the Director of the System Oversight
Division.
Regulatory Findings
amozie on DSK3GDR082PROD with RULES
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,
VerDate Sep<11>2014
16:15 Nov 06, 2018
Jkt 247001
(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.

Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
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. This AD was prompted by
reports of damage to the protective coating and corrosion on the
piston/axle of the main landing gear (MLG), caused by friction between
the inboard axle sleeve and the axle thrust face. This AD requires
revising the maintenance or inspection program, as applicable, to
incorporate a detailed inspection of the MLG piston/axle for damage to
the protective coating and for corrosion. We are issuing this AD to
address the unsafe condition on these products.
DATES: This AD is effective December 12, 2018.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of December 12,
2018.

SUPPLEMENTARY INFORMATION:
Discussion
We 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 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 July 6, 2018 (83 FR 31504). The NPRM was prompted by
reports of damage to the protective coating and corrosion on the
piston/axle of the MLG, caused by friction between the inboard axle
sleeve and the axle thrust face. The NPRM proposed to require revising
the maintenance or inspection program, as applicable, to incorporate a
detailed inspection of the MLG piston/axle for damage to the protective
coating and for corrosion.
We are issuing this AD to address damage to the protective coating
and corrosion found on the piston/axle of the MLG, caused by friction
between the inboard axle sleeve and the axle thrust face, which could
cause the axle to separate from the piston/axle, and ultimately lead to
collapse of the landing gear during ground maneuvers or upon landing.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2017-38, dated December
20, 2017 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain 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 reports of damage to the protective coating and/
or corrosion on the piston/axle of the Main Landing Gear (MLG). The
damage to the protective coating was caused by friction between the
inboard axle sleeve and the axle thrust face. If not corrected, this
condition can cause the axle to separate from the piston/axle [and
consequent collapse of the landing gear during ground maneuvers or
upon landing].
This [Canadian] AD mandates the incorporation of a new
maintenance task in order to perform a [detailed] visual inspection
of the piston/axle of the MLG to prevent the axle separation from
the piston/axle.
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-2018-
0551.
Comments
We 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.
Support for the NPRM
The Air Line Pilots Association, International and Endeavor Air
stated their support for the proposed AD.
Request To Refer to Certain Revised Service Information
Endeavor Air noted that Bombardier, Inc. has issued certain revised
service information and requested that the proposed AD be updated to
reference the revised service information.
We agree with the commenter's request. We have determined the
revised service information should be referenced in regards to
calculating the time since piston/axle entry into service, since
operators might have done the latest inspection, restoration, or repair
using the revised service information. We have updated paragraph (h) of
this AD to refer to the revised service information and reorganized
paragraph (h) of this AD for consistency.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this final rule with the changes described previously and minor
editorial changes. We have 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.
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of this final
rule.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc. has issued CRJ Series Regional Jet Temporary
Revision (TR) MRB-0059, dated March 20, 2015. The service information
describes an airworthiness limitation task for a detailed inspection
for damage to the protective coating and for corrosion on the piston/
axle of the MLG. 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.
Costs of Compliance
We estimate that this AD affects 530 airplanes of U.S. registry. We
estimate the following costs to comply with this AD:
We have determined that revising the maintenance or inspection
program takes an average of 90 work-hours per operator, although we
recognize that this number may vary from operator to operator. In the
past, we have estimated that this action takes 1 work-hour per
airplane. Since operators incorporate maintenance or inspection program
changes for their affected fleet(s), we have determined that a per-
operator estimate is more accurate than a per-airplane estimate.
Therefore, we estimate the total cost per operator to be $7,650 (90
work-hours x $85 per work-hour).
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
[[Page 55608]]
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 and
associated appliances to the Director of the System Oversight Division.
Regulatory Findings
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.
