Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
Bombardier, Inc., Model CL–600–1A11
(CL–600), CL–600–2A12 (CL–601
Variant), and CL–600–2B16 (CL–601–3A
and CL–601–3R Variants) airplanes.
This proposed AD was prompted by a
report of laminated shims that may have
been improperly installed at a certain
wing tie beam. This proposed AD would
require revising the maintenance or
inspection program to incorporate
certification maintenance requirement
tasks that introduce revised checks of
the tie beam. We are proposing this AD
to address the unsafe condition on these
products.
DATES: We must receive comments on
this proposed AD by August 31, 2017.
ADDRESSES: You may send comments,
using the procedures found in 14 CFR
11.43 and 11.45, by any of the following

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2016–34,
dated October 14, 2016 (referred to after
this as the Mandatory Continuing
Airworthiness Information, or ’’the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc., Model CL–
600–1A11 (CL–600), CL–600–2A12 (CL–
601 Variant), and CL–600–2B16 (CL–
601–3A and CL–601–3R Variants)
airplanes. The MCAI states:
Bombardier has determined that laminated
shims may have been improperly installed at
the floor/wing tie beam bumper pads.
Improperly installed shims may become
PO 00000
Frm 00004

Sfmt 4702
damaged, which could result in a gapping
condition. This would lead to increased
stress and degradation of structural integrity
of the tie beam. Undetected failure may lead
to premature cracking of the pressure floor.
Bombardier has introduced revised
maintenance tasks through revisions of the
applicable CL–600 Time Limits Maintenance
Checks (TLMCs) to confirm structural
integrity of the affected tie beam.
This [Canadian] AD is issued to mandate
the incorporation of the applicable revised
TLMC tasks.
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–
0691.
This proposed AD will require
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 (i)(1) of this proposed AD.
The request should include a
description of changes to the required
actions that will ensure the continued
operational safety of the airplane.

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.
Costs of Compliance
We estimate that this proposed AD
affects 137 airplanes of U.S. registry.
We estimate the following costs to
comply with this proposed AD:
ESTIMATED COSTS
Action
Labor cost
Maintenance or inspection program revision ..
1 work-hour × $85 per hour = $85 per airplane.

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.
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.

Improperly installed shims may become damaged, which could result in
a gapping condition. This would lead to increased stress and
degradation of structural integrity of the tie beam. Undetected
failure may lead to premature cracking of the pressure floor.
Bombardier has introduced revised maintenance tasks through
revisions of the applicable CL-600 Time Limits Maintenance Checks
(TLMCs) to confirm structural integrity of the affected tie beam.
This [Canadian] AD is issued to mandate the incorporation of the
applicable revised TLMC tasks.
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-
0691.
This proposed AD will require 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
(i)(1) of this proposed AD. The request should include a description of
changes to the required actions that will ensure the continued
operational safety of the airplane.

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.
Costs of Compliance
We estimate that this proposed AD affects 137 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Maintenance or inspection program 1 work-hour x $85 per $0 $85 $11,645
revision. hour = $85 per airplane.

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.
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.
