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: Two cases of a crack on a
‘‘dry’’ ADG (Air Driven Generator)
(Hamilton Sundstrand part number in
the 761339 series) in the aft area of the
strut and generator housing assembly,
have been reported on CL–600–2B19
aircraft. The same part number is also
installed on CL–600–2B16 (CL–604)
aircraft. Investigation determined that
the crack was in an area of the strut
where the wall thickness of the casting
was below specification, due to a
manufacturing anomaly in a specific
batch of ADGs. Structural failure and
departure of the ADG during
deployment could possibly result in
damage to the aircraft structure. If
deployment were activated by a dual
engine shutdown, ADG structural
failure would also result in loss of
hydraulics for the flight controls. The
unsafe condition is possible loss of
control 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 February 18, 2010.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the airworthiness
authority for Canada, has issued
Canadian Airworthiness Directive CF–
2009–24, issued May 19, 2009 (referred
to after this as ‘‘the MCAI’’), to correct
an unsafe condition for the specified
products. The MCAI states:
Two cases of a crack on a ‘‘dry’’ ADG (Air
Driven Generator) (Hamilton Sundstrand part
number in the 761339 series) in the aft area
of the strut and generator housing assembly,
have been reported on CL–600–2B19 aircraft.
The same part number is also installed on
CL–600–2B16 (CL–604) aircraft. Investigation
determined that the crack was in an area of
the strut where the wall thickness of the
casting was below specification, due to a
manufacturing anomaly in a specific batch of
ADGs. Structural failure and departure of the
ADG during deployment could possibly
result in damage to the aircraft structure. If
deployment were activated by a dual engine
shutdown, ADG structural failure would also
result in loss of hydraulics for the flight
controls.
This directive gives instructions to check
the part number of the installed ADG and, for
ADGs with a part number in the 761339
series, the serial numbers of the ADG and the
strut and generator housing assembly are also
to be checked. If these serial numbers are
within specified ranges * * *, initial and
subsequent repeat fluorescent penetrant
inspections of the ADG strut are required.
This directive also gives instructions to
perform a fluorescent penetrant inspection
after each unscheduled in-flight ADG
deployment and a [general] visual inspection
after each unscheduled on-ground ADG
deployment. Instructions regarding reidentification (where applicable) and
replacement parts are also included.
The unsafe condition is possible loss of
control of the airplane. You may obtain
further information by examining the
MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Alert Service
Bulletin A604–24–017, Revision 01,
dated January 15, 2007; and Service
Bulletin 604–24–019, dated October 1,
2007. The actions described in this
service information are intended to
correct the unsafe condition identified
in the MCAI.

Federal Register / Vol. 75, No. 1 / Monday, January 4, 2010 / Proposed Rules
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 378 products of U.S.
registry. We also estimate that it would
take about 2 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would cost about $0 per product.
Where the service information lists
required parts costs that are covered
under warranty, we have assumed that
there will be no charge for these costs.
As we do not control warranty coverage
for affected parties, some parties may
incur costs higher than estimated here.
Based on these figures, we estimate the
cost of the proposed AD on U.S.
operators to be $60,480, or $160 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.
VerDate Nov<24>2008
17:10 Dec 31, 2009
Jkt 220001
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.
Comments Due Date
(a) We must receive comments by February
18, 2010.
Regulatory Findings
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Two cases of a crack on a ‘‘dry’’ ADG (Air
Driven Generator) (Hamilton Sundstrand part
number in the 761339 series) in the aft area
of the strut and generator housing assembly,
have been reported on CL–600–2B19 aircraft.
The same part number is also installed on
CL–600–2B16 (CL–604) aircraft. Investigation
determined that the crack was in an area of
the strut where the wall thickness of the
casting was below specification, due to a
manufacturing anomaly in a specific batch of
ADGs. Structural failure and departure of the
ADG during deployment could possibly
result in damage to the aircraft structure. If
deployment were activated by a dual engine
shutdown, ADG structural failure would also
result in loss of hydraulics for the flight
controls.
This directive gives instructions to check
the part number of the installed ADG and, for
ADGs with a part number in the 761339
series, the serial numbers of the ADG and the
strut and generator housing assembly are also
to be checked. If these serial numbers are
within specified ranges * * *, initial and
subsequent repeat fluorescent penetrant
inspections of the ADG strut are required.
This directive also gives instructions to
perform a fluorescent penetrant inspection
after each unscheduled in-flight ADG
deployment and a [general] visual inspection
after each unscheduled on-ground ADG
deployment. Instructions regarding reidentification (where applicable) and
replacement parts are also included.
The unsafe condition is possible loss of
control of the airplane.
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); 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.

of data described in § 301.7216–
1(b)(3)(i)(B) under § 301.7216–2(o), and
disclose and use tax return information
for the purpose of performing conflict
reviews under § 301.7216–2(p).
Temporary regulations in the Procedure
and Administration section of this issue
of the Federal Register amend 26 CFR
part 301. The text of those regulations
also serves as the text of these
regulations. The preamble to the
temporary regulations explains the
temporary regulations and these
proposed regulations.
Special Analyses
It has been determined that this notice
of proposed rulemaking is not a
significant regulatory action as defined
in Executive Order 12866. Therefore, a
regulatory assessment is not required. It
has also been determined that section
553(b) of the Administrative Procedure
Act (5 U.S.C. chapter 5) does not apply
to these regulations, and because the
regulation does not impose a collection
of information on small entities, the
Regulatory Flexibility Act (5 U.S.C.
chapter 6) does not apply. Pursuant to
section 7805(f) of the Code, this
regulation has been submitted to the
Chief Counsel for Advocacy of the Small
Business Administration for comment
on its impact on small business.
Comments and Requests for a Public
Hearing
Before these proposed regulations are
adopted as final regulations,
consideration will be given to any
written (a signed original and eight (8)
copies) or electronic comments that are
submitted timely to the IRS. The IRS
and the Treasury Department request
comments on the clarity of the proposed
rules, how they can be made easier to
understand, and the administrability of
the rules in the proposed regulations.
All comments will be made available for
public inspection and copying. A public

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: Two cases of a crack on a ``dry'' ADG (Air Driven
Generator) (Hamilton Sundstrand part number in the 761339 series) in
the aft area of the strut and generator housing assembly, have been
reported on CL-600-2B19 aircraft. The same part number is also
installed on CL-600-2B16 (CL-604) aircraft. Investigation determined
that the crack was in an area of the strut where the wall thickness of
the casting was below specification, due to a manufacturing anomaly in
a specific batch of ADGs. Structural failure and departure of the ADG
during deployment could possibly result in damage to the aircraft
structure. If deployment were activated by a dual engine shutdown, ADG
structural failure would also result in loss of hydraulics for the
flight controls. The unsafe condition is possible loss of control 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 February 18,
2010.

Discussion
Transport Canada Civil Aviation (TCCA), which is the airworthiness
authority for Canada, has issued Canadian Airworthiness Directive CF-
2009-24, issued May 19, 2009 (referred to after this as ``the MCAI''),
to correct an unsafe condition for the specified products. The MCAI
states:
Two cases of a crack on a ``dry'' ADG (Air Driven Generator)
(Hamilton Sundstrand part number in the 761339 series) in the aft
area of the strut and generator housing assembly, have been reported
on CL-600-2B19 aircraft. The same part number is also installed on
CL-600-2B16 (CL-604) aircraft. Investigation determined that the
crack was in an area of the strut where the wall thickness of the
casting was below specification, due to a manufacturing anomaly in a
specific batch of ADGs. Structural failure and departure of the ADG
during deployment could possibly result in damage to the aircraft
structure. If deployment were activated by a dual engine shutdown,
ADG structural failure would also result in loss of hydraulics for
the flight controls.
This directive gives instructions to check the part number of
the installed ADG and, for ADGs with a part number in the 761339
series, the serial numbers of the ADG and the strut and generator
housing assembly are also to be checked. If these serial numbers are
within specified ranges * * *, initial and subsequent repeat
fluorescent penetrant inspections of the ADG strut are required.
This directive also gives instructions to perform a fluorescent
penetrant inspection after each unscheduled in-flight ADG deployment
and a [general] visual inspection after each unscheduled on-ground
ADG deployment. Instructions regarding re-identification (where
applicable) and replacement parts are also included.
The unsafe condition is possible loss of control of the airplane. You
may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Alert Service Bulletin A604-24-017, Revision
01, dated January 15, 2007; and Service Bulletin 604-24-019, dated
October 1, 2007. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.
[[Page 92]]
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 378 products of U.S. registry. We also estimate that
it would take about 2 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $0 per product. Where the
service information lists required parts costs that are covered under
warranty, we have assumed that there will be no charge for these costs.
As we do not control warranty coverage for affected parties, some
parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $60,480, or $160 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.
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.

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. (Type Certificate Previously Held by Canadair):
Docket No. FAA-2009-1227; Directorate Identifier 2009-NM-119-AD.
Comments Due Date
(a) We must receive comments by February 18, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier, Inc. (Type Certificate
previously held by Canadair) Model CL-600-2B16 (CL-604) airplanes;
certificated in any category; serial numbers 5408 through 5665
inclusive.
Subject
(d) Air Transport Association (ATA) of America Code 24:
Electrical Power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Two cases of a crack on a ``dry'' ADG (Air Driven Generator)
(Hamilton Sundstrand part number in the 761339 series) in the aft
area of the strut and generator housing assembly, have been reported
on CL-600-2B19 aircraft. The same part number is also installed on
CL-600-2B16 (CL-604) aircraft. Investigation determined that the
crack was in an area of the strut where the wall thickness of the
casting was below specification, due to a manufacturing anomaly in a
specific batch of ADGs. Structural failure and departure of the ADG
during deployment could possibly result in damage to the aircraft
structure. If deployment were activated by a dual engine shutdown,
ADG structural failure would also result in loss of hydraulics for
the flight controls.
This directive gives instructions to check the part number of
the installed ADG and, for ADGs with a part number in the 761339
series, the serial numbers of the ADG and the strut and generator
housing assembly are also to be checked. If these serial numbers are
within specified ranges * * *, initial and subsequent repeat
fluorescent penetrant inspections of the ADG strut are required.
This directive also gives instructions to perform a fluorescent
penetrant inspection after each unscheduled in-flight ADG deployment
and a [general] visual inspection after each unscheduled on-ground
ADG deployment. Instructions regarding re-identification (where
applicable) and replacement parts are also included.
The unsafe condition is possible loss of control of the airplane.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 400 flight hours after the effective date of this AD,
inspect to determine the part number of the installed ADG and
accomplish the actions required by paragraph (f)(1)(i) or (f)(1)(ii)
of this AD, as applicable. A review of airplane maintenance records
is acceptable in lieu of this inspection if the part number of the
ADG can be conclusively determined from that review.
(i) If the part number of the ADG is 604-90800-23 (Hamilton
Sundstrand part number 1711405), the strut wall thickness is within
specification and no further action is required by this paragraph.
[[Page 93]]
(ii) If the part number of the ADG is 604-90800-1, -17 or -19
(Hamilton Sundstrand part number in the 761339 series), inspect to
determine the ADG serial number and do the applicable action
required by paragraph (f)(1)(ii)(A), (f)(1)(ii)(B), or (f)(1)(ii)(C)
of this AD. A review of airplane maintenance records is acceptable
in lieu of this inspection if the serial number of the ADG can be
conclusively determined from that review.
(A) If the serial number of the ADG is 2000 or higher, the strut
wall thickness is within specification and only re-identification is
required. Do the actions required by paragraph (f)(8) of this AD.
(B) If the serial number of the ADG is in the range 0101 through
1999 inclusive, and the symbol 24-3 is marked in the serial number
block of the identification plate, the strut wall thickness is
within specification and only re-identification is required. Do the
actions required by paragraph (f)(8) of this AD.
(C) If the serial number of the ADG is in the range 0101 through
1999 inclusive, and the symbol 24-3 is not marked in the serial
number block of the identification plate, inspect to determine the
serial number of the strut and generator housing assembly and do the
applicable action required by paragraph (f)(1)(ii)(C)(1) or
(f)(1)(ii)(C)(2) of this AD, as applicable.
Note 1: Guidance on serial number location can be found in
Figure 1, Sheet 1, of Hamilton Sundstrand Service Bulletin ERPS10AG-
24-3, Revision 3, dated March 12, 2009.
(1) If the serial number of the strut and generator housing
assembly is in the range 0001 through 2503 inclusive, the
fluorescent penetrant inspection specified in paragraph (f)(2) of
this AD is required. For airplanes on which an unscheduled in-flight
or on-ground ADG deployment has occurred after accomplishing the
actions required by this paragraph, do the actions required by
paragraph (f)(6), (f)(7), or (f)(8) of this AD, as applicable.
(2) If the serial number of the strut and generator housing
assembly is 2504 or higher, the strut wall thickness is within
specification and only re-identification is required. Do the actions
required by paragraph (f)(8) of this AD.
(2) For airplanes having a strut and generator housing assembly
identified in paragraph (f)(1)(ii)(C)(1), except for airplanes with
serial numbers 5611 through 5665 on which Bombardier conducted the
initial fluorescent penetrant inspection prior to aircraft delivery
and on which the ADG has not been replaced since aircraft delivery:
Within 400 flight hours after the effective date of this AD, do a
fluorescent penetrant inspection of the ADG strut, and replace the
ADG, as applicable, in accordance with paragraphs 2.A., 2.C., and
2.D. of the Accomplishment Instructions in Bombardier Alert Service
Bulletin A604-24-017, Revision 01, dated January 15, 2007. If the
ADG is replaced by an ADG with part number 604-90800-23 (Hamilton
Sundstrand part number 1711405), no further action is required by
this paragraph. Accomplishing the requirements in paragraph (f)(4)
of this AD is required for airplanes on which each ADG has been
inspected in accordance with this paragraph.
(3) Accomplishment of the fluorescent penetrant inspection
before the effective date of this AD in accordance with the
applicable service information identified in the Table 1 of this AD
is acceptable for compliance with the requirements of paragraph
(f)(2) of this AD.

(10) Although Bombardier Alert Service Bulletin A604-24-017,
Revision 01, dated January 15, 2007; and Service Bulletin 604-24-
019, dated October 1, 2007; specify submitting certain information
to the manufacturer, this AD does not require that submission.
FAA AD Differences
Note 5: This AD differs from the MCAI and/or service information
as follows: Although the MCAI or service information tells you to
submit information to the manufacturer, paragraph (f)(10) of this AD
specifies that such submittal is not required.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office (ACO), FAA, has the authority to
approve AMOCs for this AD, if requested using the procedures found
in 14 CFR 39.19. Send information to ATTN: Program Manager,
Continued Operational Safety, FAA, New York ACO, 1600 Stewart
Avenue, Suite 410, Westbury, New York 11590; telephone (516) 228-
7300; fax (516) 794-5531. Before using any approved AMOC on any
airplane to which the AMOC applies, notify your principal
maintenance inspector (PMI) or principal avionics inspector (PAI),
as appropriate, or lacking a principal inspector, your local Flight
Standards District Office. The AMOC approval letter must
specifically reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
