Discussion
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)

(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.

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,
to Bombardier CRJ Series Regional Jet
Maintenance Requirements Manual
(MRM), Part 1, CSP B–053. 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.
FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
This AD requires revisions to certain
operator maintenance documents to
include new actions (e.g., inspections).
Compliance with these actions is
required by 14 CFR 91.403(c). For
airplanes that have been previously
modified, altered, or repaired in the
areas addressed by this proposed AD,
the operator may not be able to
accomplish the actions described in the
VerDate Sep<11>2014
17:10 Jul 05, 2018
Jkt 244001
revisions. In this situation, to comply
with 14 CFR 91.403(c), the operator
must request approval for an alternative
method of compliance according to
paragraph (j)(1) of this proposed AD.
The request should include a
description of changes to the required
inspections that will ensure the
continued operational safety of the
airplane.
Costs of Compliance
We estimate that this proposed AD
affects 530 airplanes of U.S. registry. We
estimate the following costs to comply
with this proposed 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
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 proposed 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
PO 00000
Frm 00035
Fmt 4702
Sfmt 4702
31505
category airplanes to the Director of the
System Oversight Division.
Regulatory Findings
We determined that this proposed AD
would not have federalism implications
under Executive Order 13132. This
proposed AD would 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 this proposed regulation:
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.

such damage, 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.

to the airplane structure is not adequate
for the higher loads experienced during
survivable accidents. In addition, there
is no secondary means of retention
(lanyards) for the PSU to the airplane
structure. This condition, if not
corrected, could result in the PSU
becoming detached and falling into the
cabin, which could lead to passenger
injuries and impede egress during an
evacuation.

Airworthiness Directives; Bombardier, Inc.
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt 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 proposed
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
proposed AD would 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 proposing this AD to address the unsafe condition on these
products.

Discussion
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
[[Page 31505]]
(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.
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, to Bombardier CRJ Series
Regional Jet Maintenance Requirements Manual (MRM), Part 1, CSP B-053.
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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
This AD requires revisions to certain operator maintenance
documents to include new actions (e.g., inspections). Compliance with
these actions is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas addressed
by this proposed AD, the operator may not be able to accomplish the
actions described in the revisions. In this situation, to comply with
14 CFR 91.403(c), the operator must request approval for an alternative
method of compliance according to paragraph (j)(1) of this proposed AD.
The request should include a description of changes to the required
inspections that will ensure the continued operational safety of the
airplane.
Costs of Compliance
We estimate that this proposed AD affects 530 airplanes of U.S.
registry. We estimate the following costs to comply with this proposed
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 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 proposed 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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
