Federal Register / Vol. 75, No. 106 / Thursday, June 3, 2010 / Proposed Rules
In addition to requiring DOE to
establish new energy conservation
standards or energy use standards for
furnace fans, EPCA generally directs
DOE to establish test procedures for new
covered products, such as furnace fans.
(42 U.S.C. 6295(r)) Furthermore, section
310(3) of the Energy Independence and
Security Act of 2007 (EISA 2007)
amended EPCA to require that any new
or amended energy conservation
standard adopted after July 1, 2010,
shall address standby mode and off
mode energy use pursuant to 42 U.S.C.
6295(o). (42 U.S.C. 6295(gg)(3))
Pursuant to these mandates, DOE is also
initiating a furnace fan test procedure
rulemaking at this time. Accordingly,
DOE is including in this framework
document its preliminary review of any
industry test procedures or testing
methods used to characterize the
performance of furnace fans in all
modes of operation. DOE has also
outlined a number of issues for
comment regarding the testing of
furnace fans, and it will consider the
feedback received in response to this
framework document in its
development of a proposed test
procedure for furnace fans. DOE intends
to issue a separate notice of proposed
rulemaking (NOPR) addressing the test
procedures for furnace fans. When the
furnace fan test procedure final rule is
published, DOE will have complied
with EPCA’s statutory requirements for
test procedures.
To initiate the furnace fan
rulemaking, DOE has prepared a
framework document to explain the
issues, analyses, and processes it
anticipates using in considering the
development of new energy
conservation standards or energy use
standards for furnace fans. Also
included in this framework document is
a detailed summary of a preliminary test
procedure that DOE is considering for
use in developing its own test procedure
and for use in the development of
energy conservation standards for
furnace fans.
The main focus of the public meeting
noted above will be to discuss the
analyses presented and issues identified
in the framework document. At the
public meeting, DOE will make a
number of presentations, invite
discussion on the rulemaking process as
it applies to certain furnace fans, and
solicit comments, data, and information
from participants and other interested
parties. DOE will also invite comment
on its preliminary determination of the
scope of coverage for the furnace fan
energy conservation standard and its
preliminary analysis of the development
of a test procedure for furnace fans.

DOE encourages those who wish to
participate in the public meeting to
obtain the framework document and to
be prepared to discuss its contents. A
copy of the framework document is
available at: www.eere.energy.gov/
buildings/appliance_standards/
residential/furnace_fans.html.
Public meeting participants need not
limit their comments to the issues
identified in the framework document.
DOE is also interested in comments on
other relevant issues that participants
believe would affect energy
conservation standards or energy use
standards for this product, applicable
test procedures, or the preliminary
determination on the scope of coverage.
DOE invites all interested parties,
whether or not they participate in the
public meeting, to submit in writing by
July 6, 2010 comments and information
on matters addressed in the framework
document and on other matters relevant
to DOE’s consideration of new standards
for furnace fans.
The public meeting will be conducted
in an informal, facilitated, conference
style. There shall be no discussion of
proprietary information, costs or prices,
market shares, or other commercial
matters regulated by U.S. antitrust laws.
A court reporter will record the
proceedings of the public meeting, after
which a transcript will be available for
purchase from the court reporter and
placed on the DOE Web site at:
www.eere.energy.gov/buildings/
appliance_standards/residential/
furnace_fans.html.
After the public meeting and the close
of the comment period, DOE will begin
collecting data, conducting the analyses
as discussed in the framework
document and at the public meeting,
and reviewing the public comments.
These actions will be taken to develop
an energy conservation standards NOPR
and separate test procedure NOPR for
furnace fans.
DOE considers public participation to
be a very important part of the process
for setting energy conservation
standards. DOE actively encourages the
participation and interaction of the
public during the comment period in
each stage of the rulemaking process.
Beginning with the framework
document, and during each subsequent
public meeting and comment period,
interactions with and between members
of the public provide a balanced
discussion of the issues and assist DOE
in the standards rulemaking process.
Anyone who wishes to participate in the
public meeting, receive meeting

ACTION: Notice of proposed rulemaking
(NPRM).
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for the
products listed above. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as: There have been several
Stick Pusher Capstan Shaft failures
causing severe degradation of the stick
pusher function. This directive is issued
to revise the first flight of the day check
of the stall protection system to detect
degradation of the stick pusher function.
It also introduces a new repetitive
maintenance task to limit exposure to
dormant failure of the stick pusher
capstan shaft. Dormant loss or severe
degradation of the stick pusher function
could result in reduced controllability
of the airplane. The proposed AD would
require actions that are intended to
address the unsafe condition described
in the MCAI.
DATES: We must receive comments on
this proposed AD by July 19, 2010.

Discussion
Transport Canada Civil Aviation,
which is the aviation authority for
Canada, has issued Canadian
Airworthiness Directive CF–2009–36,
dated September 2, 2009 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
There have been several Stick Pusher
Capstan Shaft failures causing severe
degradation of the stick pusher function. This
directive is issued to revise the first flight of
the day check of the stall protection system
to detect degradation of the stick pusher
function. It also introduces a new repetitive
maintenance task to limit exposure to
dormant failure of the stick pusher capstan
shaft.
Dormant loss or severe degradation of
the stick pusher function could result in
reduced controllability of the airplane.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Temporary
Revision (TR) 2A–43, dated May 7,
2008, to Appendix A—Certification
Maintenance Requirements of Part 2 of
the Bombardier CL–600–2B19
Maintenance Requirements Manual; and
Canadair Regional Jet TR RJ/178–1,
dated March 8, 2010, to Canadair
Regional Jet Airplane Flight Manual
CSP A–012. The actions described in
this service information are intended to
correct the unsafe condition identified
in the MCAI.
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.

Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a Note within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 601 products of U.S.
registry. We also estimate that it would
take about 1 work-hour per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$51,085, or $85 per product.
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.

Federal Register / Vol. 75, No. 106 / Thursday, June 3, 2010 / Proposed Rules
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); and
3. 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc.
Model CL–600–2B19 (Regional Jet Series 100
& 440) airplanes, certificated in any category,
serial numbers 7003 through 7990 inclusive,
and 8000 and subsequent.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
inspections 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 (h)(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.

Subject
(d) Air Transport Association (ATA) of
America Code 27: Flight controls.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
There have been several Stick Pusher
Capstan Shaft failures causing severe
degradation of the stick pusher function. This
directive is issued to revise the first flight of
the day check of the stall protection system
to detect degradation of the stick pusher
function. It also introduces a new repetitive
maintenance task to limit exposure to
dormant failure of the stick pusher capstan
shaft.
Dormant loss or severe degradation of the
stick pusher function could result in reduced
controllability of the airplane.
Compliance
(f) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the following actions.
(1) Within 30 days after the effective date
of this AD, revise the Limitations section of
Canadair Regional Jet Airplane Flight Manual
(AFM) CSP A–012 to include the information
in Canadair Regional Jet Temporary Revision
(TR) RJ/178–1, dated March 8, 2010; as
specified in the TR. The Canadair Regional
Jet TR RJ/178–1, dated March 8, 2010,
introduces procedures for performing a stall
protection system test. Operate the airplane
according to the limitations and procedures
in the Canadair Regional Jet TR RJ/178–1,
dated March 8, 2010.
Note 2: This may be done by inserting a
copy of Canadair Regional Jet TR RJ/178–1,
dated March 8, 2010, into the Canadair
Regional Jet AFM CSP A–012. When this
Canadair Regional Jet TR has been included
in general revisions of the Canadair Regional
Jet AFM, the general revisions may be
inserted in the AFM, provided the relevant
information in the general revision is
identical to that in the Canadair Regional Jet
TR.
(2) Within 30 days after the effective date
of this AD, revise Appendix A—Certification
Maintenance Requirements of Part 2 of the
Bombardier CL–600–2B19 Maintenance
Requirements Manual (MRM) by
incorporating the information in Bombardier
TR 2A–43, dated May 7, 2008; as specified
in the TR. The initial compliance time for the
new MRM task identified in the TR is at the
later of the times specified in paragraphs
(g)(2)(i) and (g)(2)(ii) of this AD. Thereafter,
except as provided by paragraph (h)(1) of this
AD, no alternative task intervals may be
used. The TR to the MRM introduces
procedures for a function check of the stick
pusher capstan.
(i) Prior to the accumulation of 5,000 total
flight hours.
(ii) Within 500 flight hours after the
effective date of this AD.

ACTION: Notice of proposed rulemaking
(NPRM).
SUMMARY: We propose to adopt a new
airworthiness directive (AD) for all
Model 757 airplanes. This proposed AD
would require a detailed inspection of
the inboard and outboard main track
downstop assemblies and a torque
application to the main track downstop
assembly nuts of slat numbers 1 through
10, excluding the outboard track of slats
1 and 10, a detailed inspection of all slat
track housings, and related corrective
actions if necessary. This proposed AD
results from reports of fuel leaking from
the front spar of the wing through the
slat track housing. We are proposing
this AD to detect and correct incorrectly
installed main track downstop
assemblies, which, when the slat is
retracted, could cause a puncture in the
slat track housing leading to a fuel leak
and potential fire.
DATES: We must receive comments on
this proposed AD by July 19, 2010.
ADDRESSES: You may send comments by
any of the following methods:

support rib, subsequently punctured the
slat track housing when the slat was
retracted. While fuel leaking from a
punctured slat track housing could lead
to a fire, in both cases, no fires were
reported.
Relevant Service Information
We have reviewed Boeing Special
Attention Bulletin 757–57–0068, dated
September 15, 2009. That service
bulletin describes procedures for doing
a detailed inspection of the inboard and
outboard main track downstop
assemblies and for applying torque to
the main track downstop assembly nuts
of slat numbers 1 through 10, excluding
the outboard track of slats 1 and 10.
That service bulletin also describes
procedures for doing a detailed
inspection of both inboard and outboard
slat track housings of slat numbers 1
through 10 for foreign object debris or
visible damage, and doing corrective
actions if necessary. Boeing Special
Attention Bulletin 757–57–0068, dated
September 15, 2009, specifies the
following corrective actions:
• Removing and reinstalling
incorrectly installed main track
downstop assemblies.
• Replacing damaged or missing main
track downstop assembly parts.
• Removing foreign object debris.
• Repairing or replacing damaged slat
track housings.
• Contacting Boeing for repair
instructions.
Boeing Special Attention Bulletin
757–57–0068, dated September 15,
2009, specifies that the detailed
inspections of the main track downstop
assembles and the slat track housings be
done before 24 months after the date on
that service bulletin. That service
bulletin also specifies that application
of torque to the main track downstop
assembly nuts be done before 24 months
after the date on that service bulletin.
That service bulletin also specifies that
corrective actions be done before further
flight.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as: There have been several Stick Pusher Capstan Shaft
failures causing severe degradation of the stick pusher function. This
directive is issued to revise the first flight of the day check of the
stall protection system to detect degradation of the stick pusher
function. It also introduces a new repetitive maintenance task to limit
exposure to dormant failure of the stick pusher capstan shaft. Dormant
loss or severe degradation of the stick pusher function could result in
reduced controllability of the airplane. The proposed AD would require
actions that are intended to address the unsafe condition described in
the MCAI.
DATES: We must receive comments on this proposed AD by July 19, 2010.
ADDRESSES: You may send comments by any of the following methods:

Discussion
Transport Canada Civil Aviation, which is the aviation authority
for Canada, has issued Canadian Airworthiness Directive CF-2009-36,
dated September 2, 2009 (referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
There have been several Stick Pusher Capstan Shaft failures
causing severe degradation of the stick pusher function. This
directive is issued to revise the first flight of the day check of
the stall protection system to detect degradation of the stick
pusher function. It also introduces a new repetitive maintenance
task to limit exposure to dormant failure of the stick pusher
capstan shaft.
Dormant loss or severe degradation of the stick pusher function
could result in reduced controllability of the airplane. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Temporary Revision (TR) 2A-43, dated May 7,
2008, to Appendix A--Certification Maintenance Requirements of Part 2
of the Bombardier CL-600-2B19 Maintenance Requirements Manual; and
Canadair Regional Jet TR RJ/178-1, dated March 8, 2010, to Canadair
Regional Jet Airplane Flight Manual CSP A-012. The actions described in
this service information are intended to correct the unsafe condition
identified in the MCAI.
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.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a Note within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 601 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $51,085, or $85 per product.
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.
[[Page 31326]]
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); and
3. 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
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:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Bombardier, Inc.: Docket No. FAA-2010-0482; Directorate Identifier
2009-NM-225-AD.
Comments Due Date
(a) We must receive comments by July 19, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, certificated in any
category, serial numbers 7003 through 7990 inclusive, and 8000 and
subsequent.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections is required by 14 CFR 91.403(c). For airplanes
that have been previously modified, altered, or repaired in the
areas addressed by these inspections, the operator may not be able
to accomplish the inspections 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 (h)(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.
Subject
(d) Air Transport Association (ATA) of America Code 27: Flight
controls.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
There have been several Stick Pusher Capstan Shaft failures
causing severe degradation of the stick pusher function. This
directive is issued to revise the first flight of the day check of
the stall protection system to detect degradation of the stick
pusher function. It also introduces a new repetitive maintenance
task to limit exposure to dormant failure of the stick pusher
capstan shaft.
Dormant loss or severe degradation of the stick pusher function
could result in reduced controllability of the airplane.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the following actions.
(1) Within 30 days after the effective date of this AD, revise
the Limitations section of Canadair Regional Jet Airplane Flight
Manual (AFM) CSP A-012 to include the information in Canadair
Regional Jet Temporary Revision (TR) RJ/178-1, dated March 8, 2010;
as specified in the TR. The Canadair Regional Jet TR RJ/178-1, dated
March 8, 2010, introduces procedures for performing a stall
protection system test. Operate the airplane according to the
limitations and procedures in the Canadair Regional Jet TR RJ/178-1,
dated March 8, 2010.
Note 2: This may be done by inserting a copy of Canadair
Regional Jet TR RJ/178-1, dated March 8, 2010, into the Canadair
Regional Jet AFM CSP A-012. When this Canadair Regional Jet TR has
been included in general revisions of the Canadair Regional Jet AFM,
the general revisions may be inserted in the AFM, provided the
relevant information in the general revision is identical to that in
the Canadair Regional Jet TR.
(2) Within 30 days after the effective date of this AD, revise
Appendix A--Certification Maintenance Requirements of Part 2 of the
Bombardier CL-600-2B19 Maintenance Requirements Manual (MRM) by
incorporating the information in Bombardier TR 2A-43, dated May 7,
2008; as specified in the TR. The initial compliance time for the
new MRM task identified in the TR is at the later of the times
specified in paragraphs (g)(2)(i) and (g)(2)(ii) of this AD.
Thereafter, except as provided by paragraph (h)(1) of this AD, no
alternative task intervals may be used. The TR to the MRM introduces
procedures for a function check of the stick pusher capstan.
(i) Prior to the accumulation of 5,000 total flight hours.
(ii) Within 500 flight hours after the effective date of this
AD.
Note 3: The actions required by paragraph (g)(2) of this AD may
be done by inserting a copy of Bombardier TR 2A-43, dated May 7,
2008, to Appendix A--Certification Maintenance Requirements of Part
2 of the Bombardier CL-600-2B19 MRM. When this Bombardier TR has
been included in general revisions of the Bombardier MRM, the
Bombardier TR may be removed from the MRM, provided the relevant
information in the general revision is identical to that in
Bombardier TR 2A-43, dated May 7, 2008.
