bolts on the horizontal stabilizer trim
actuator (HSTA). This proposed AD
would require a revision to the airplane
flight manual, a revision to the
maintenance or inspection program, and
replacement of HSTAs having certain
part numbers. We are proposing this AD
to detect and correct loose spur gear
bolts on the HSTA, which, if combined
with the failure of the primary load
path, could lead to failure of the HSTA
and subsequent loss of control of the
airplane.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2013–18,
dated July 16, 2013 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
E:\FR\FM\15APP1.SGM
15APP1
Federal Register / Vol. 79, No. 72 / Tuesday, April 15, 2014 / Proposed Rules
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc. Model CL–
600–2B16 (CL–604 Variant) airplanes.
The MCAI states:
There have been a number of reports where
the HSTA [horizontal stabilizer trim actuator]
spur gear bolts were found loose, broken or
backed out. Investigation revealed that the
root cause of the bolt loosening is due to
incorrect bending of the anti-rotation tab
washer and the improper application of
Loctite glue during installation. Loose bolt(s)
on the HSTA spur gear combined with the
failure of the primary load path, could lead
to failure of the HSTA and subsequent loss
of the aeroplane.
Bombardier Aerospace has introduced a
modified HSTA [part number] P/N 604–
92305–5 (vendor P/N 8454–2) to rectify the
loose bolt problem. However, this modified
HSTA has several quality control problems
which could affect safety.
This [Canadian] AD is issued to mandate
the replacement of the affected HSTA with
the new HSTA P/N 604–92305–7 (vendor P/
N 8454–3).
In addition to replacing any HSTA
having the affected part number, this
proposed AD would require revising
both the airplane flight manual and
airplane maintenance or inspection
program.
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–2014–
0231.

Relevant Service Information
Bombardier, Inc. has issued the
service information specified below.
The actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.
• Bombardier Temporary Revision
604/37, dated May 21, 2013, to the
Bombardier CL–604 Airplane Flight
Manual, PSP 604–1.
• Bombardier Temporary Revision
605/18, dated May 21, 2013, to the
Bombardier CL–605 Airplane Flight
Manual, PSP 605–1.
• Bombardier Revision Submission
RS–CL604–055, dated April 27, 2012, to
the Bombardier CL–604 Airplane Flight
Manual, PSP 604–1.
• Bombardier Revision Submission
RS–CL605–030, dated April 27, 2012, to
the Bombardier CL–605 Airplane Flight
Manual, PSP 605–1.
• Bombardier Service Bulletin 604–
27–032, dated September 10, 2012.
• Bombardier Service Bulletin 605–
27–002, dated September 10, 2012.
RS–CL604–055 and RS–CL605–030 are
dated April 30, 2012; however, the date
that appears on those documents is
April 27, 2012. We contacted
Bombardier and verified that the dates
on the documents are correct.
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 proposed AD would 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 the
procedure specified in paragraph (l)(1)
of this AD. The request should include
a description of changes to the required
inspections that will ensure the
continued operational safety of the
airplane.
Clarification of Document Date
Costs of Compliance
We estimate that this proposed AD
affects 125 airplanes of U.S. registry.
We also estimate that it would take
about 21 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Required
parts would cost about $0 per product.
Based on these figures, we estimate the
cost of this proposed AD on U.S.
operators to be $223,125, or $1,785 per
product.
According to the manufacturer, some
of the costs of this proposed AD may be
covered under warranty, thereby
reducing the cost impact on affected
individuals. We do not control warranty
coverage for affected individuals. As a
result, we have included all costs in our
cost estimate.

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.

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-18, dated July 16, 2013 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the
[[Page 21159]]
MCAI''), to correct an unsafe condition for certain Bombardier, Inc.
Model CL-600-2B16 (CL-604 Variant) airplanes. The MCAI states:
There have been a number of reports where the HSTA [horizontal
stabilizer trim actuator] spur gear bolts were found loose, broken
or backed out. Investigation revealed that the root cause of the
bolt loosening is due to incorrect bending of the anti-rotation tab
washer and the improper application of Loctite glue during
installation. Loose bolt(s) on the HSTA spur gear combined with the
failure of the primary load path, could lead to failure of the HSTA
and subsequent loss of the aeroplane.
Bombardier Aerospace has introduced a modified HSTA [part
number] P/N 604-92305-5 (vendor P/N 8454-2) to rectify the loose
bolt problem. However, this modified HSTA has several quality
control problems which could affect safety.
This [Canadian] AD is issued to mandate the replacement of the
affected HSTA with the new HSTA P/N 604-92305-7 (vendor P/N 8454-3).
In addition to replacing any HSTA having the affected part number, this
proposed AD would require revising both the airplane flight manual and
airplane maintenance or inspection program.

0231.
Relevant Service Information
Bombardier, Inc. has issued the service information specified
below. The actions described in this service information are intended
to correct the unsafe condition identified in the MCAI.
Bombardier Temporary Revision 604/37, dated May 21, 2013,
to the Bombardier CL-604 Airplane Flight Manual, PSP 604-1.
Bombardier Temporary Revision 605/18, dated May 21, 2013,
to the Bombardier CL-605 Airplane Flight Manual, PSP 605-1.
Bombardier Revision Submission RS-CL604-055, dated April
27, 2012, to the Bombardier CL-604 Airplane Flight Manual, PSP 604-1.
Bombardier Revision Submission RS-CL605-030, dated April
27, 2012, to the Bombardier CL-605 Airplane Flight Manual, PSP 605-1.
Bombardier Service Bulletin 604-27-032, dated September
10, 2012.
Bombardier Service Bulletin 605-27-002, dated September
10, 2012.
Clarification of Document Date
Canadian Airworthiness Directive CF-2013-18, dated July 16, 2013,
states that Bombardier Revision Submissions RS-CL604-055 and RS-CL605-
030 are dated April 30, 2012; however, the date that appears on those
documents is April 27, 2012. We contacted Bombardier and verified that
the dates on the documents are correct.
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 proposed AD would 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 the
procedure specified in paragraph (l)(1) of this 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 125 airplanes of U.S.
registry.
We also estimate that it would take about 21 work-hours per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Required parts would cost about $0 per
product. Based on these figures, we estimate the cost of this proposed
AD on U.S. operators to be $223,125, or $1,785 per product.
According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.
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.
List of Subjects in 14 CFR Part 39
