AGENCY: We are adopting a new airworthiness directive (AD) for the products listed above. This 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: SUMMARY: Seven cases of on-ground hydraulic accumulator screw cap/end cap failure have been experienced on CL–600–2B19 aeroplanes, resulting in the loss of the associated hydraulic system and high-energy impact damage to adjacent systems and structure. * * * * * * * * A detailed analysis of the calculated line of trajectory of a failed screw cap/end cap for each of the accumulators has been conducted, resulting in the identification of several areas where systems and/or structural components could potentially be damaged. Although all of the failures to date have occurred on the ground, an in-flight failure affecting such components could potentially have an adverse effect on the controllability of the aeroplane. emcdonald on DSK2BSOYB1PROD with RULES * * * * * This AD requires actions that are intended to address the unsafe condition described in the MCAI.

SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2010–24, dated August 3, 2010 (referred to after this as ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: Seven cases of on-ground hydraulic accumulator screw cap/end cap failure have been experienced on CL–600–2B19 aeroplanes, resulting in the loss of the associated hydraulic system and high-energy impact damage to adjacent systems and structure. The lowest number of flight cycles accumulated at the time of failure, to date, has been 6,991 flight cycles. The part numbers (P/N) of the accumulators currently installed on CL–600– 2B19 aeroplanes are 601R75138–1 (08– 60163–001 or 08–60163–002) [Hydraulic System No. 1, Hydraulic System No. 2, Inboard Brake and Outboard Brake accumulators] and 601R75138–3 (08–60164– 001 or 08–60164–002) [Hydraulic System No. 3 accumulator]. A detailed analysis of the calculated line of trajectory of a failed screw cap/end cap for each of the accumulators has been conducted, resulting in the identification of several areas where systems and/or structural components could potentially be damaged. Although all of the failures to date have occurred on the ground, an in-flight failure affecting such components could potentially have an adverse effect on the controllability of the aeroplane. This directive gives instructions to amend the Airplane Flight Manual (AFM), remove two accumulators (Hydraulic System No. 2 and No. 3) from the aeroplane and conduct repetitive ultrasonic inspections [for cracks] of the Hydraulic System No. 1, Inboard Brake and Outboard Brake accumulators that are not identified by the letter ‘‘T’’ after the serial number (S/N) on the identification plate for cracks until they are replaced by new accumulators P/N 601R75139–1 (11093–4). Required actions also include deactivating the hydraulic system No. 3 accumulator. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier has issued Canadair Regional Jet Temporary Revision (TR) RJ/186–1, dated August 24, 2010, to the Limitations section, Normal Procedures section, and Abnormal Procedures section of the Canadair Regional Jet Airplane Flight Manual (AFM), CSP A– 012. Canadair Regional Jet TR RJ/186–1, dated August 24, 2010, advises the flightcrew that for certain airplanes the hydraulic 3B pump is selected ‘‘on’’ instead of ‘‘auto’’ for all phases of flight. Bombardier has issued the service information in the following table: BOMBARDIER SERVICE BULLETINS Document Revision Bombardier Alert Service Bulletin A601R–29–029, including Appendix A, dated October 18, 2007.

The actions described in this service information as outlined in the ‘‘Discussion’’ section above, are intended to correct the unsafe condition identified in the MCAI. FAA’s Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. Differences Between the 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 required 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 AD. emcdonald on DSK2BSOYB1PROD with RULES Explanation of Affected Accumulators The actions specified in the MCAI apply only to Tactair accumulators. Certain actions in this AD apply to all accumulators. This is a result of the unsafe condition, which is due to the location of the accumulators and potential damage resulting from the release of the accumulator screw cap/ end cap. This is the reason for the deactivation of the hydraulic system No. 3 accumulator and removal of the hydraulic system No. 2 accumulator. VerDate Mar<15>2010 16:03 Oct 19, 2010 Jkt 223001 Interim Action This AD does not require the removal of the hydraulic system No. 3 accumulator, or replacement of the hydraulic system No. 1, inboard brake, and outboard brake accumulators, in Part IV and Part VII of the Canadian Airworthiness Directive CF–2010–24, dated August 3, 2010. The planned compliance time for the removal of the hydraulic system No. 3 accumulator, or replacement of the hydraulic system No. 1, inboard brake, and outboard brake accumulators, in Part IV and Part VII of the Canadian Airworthiness Directive CF–2010–24, dated August 3, 2010, would allow enough time to provide notice and opportunity for prior public comment on the merits of those actions. Therefore, we are considering further rulemaking to address this issue. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because seven cases of on-ground hydraulic accumulator screw cap/end cap failure have been experienced on Model CL–600–2B19 airplanes, resulting in the loss of the associated hydraulic system and high-energy impact damage to adjacent systems and structure. The lowest number of flight cycles accumulated at the time of failure, to date, has been 6,991 flight cycles. A detailed analysis of the calculated line of trajectory of a failed screw cap/ end cap for each of the accumulators has been conducted, resulting in the identification of several areas where systems and/or structural components could potentially be damaged, fuel lines and wires included. Although all of the failures to date have occurred on the ground, an in-flight failure affecting such components could consequently reduce the controllability of the airplane. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists PO 00000 Frm 00017 Fmt 4700 Sfmt 4700 Date for making this amendment effective in fewer than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2010–1037; Directorate Identifier 2010–NM–202– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD because of those comments. We will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. 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. E:\FR\FM\20OCR1.SGM 20OCR1 64638 Federal Register / Vol. 75, No. 202 / Wednesday, October 20, 2010 / Rules and Regulations Regulatory Findings We determined that this AD will not have federalism implications under Executive Order 13132. This AD will 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 AD: 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 AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:

Discussion

Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2010-24, dated August 3, 2010 (referred to after this as ``the MCAI''),
to correct an unsafe condition for the specified products. The MCAI
states:

Seven cases of on-ground hydraulic accumulator screw cap/end cap
failure have been experienced on CL-600-2B19 aeroplanes, resulting
in the loss of the associated hydraulic system and high-energy
impact damage to adjacent systems and structure. The lowest number
of flight cycles accumulated at the time of failure, to date, has
been 6,991 flight cycles.
The part numbers (P/N) of the accumulators currently installed
on CL-600-2B19 aeroplanes are 601R75138-1 (08-60163-001 or 08-60163-
002) [Hydraulic System No. 1, Hydraulic System No. 2, Inboard Brake
and Outboard Brake accumulators] and 601R75138-3 (08-60164-001 or
08-60164-002) [Hydraulic System No. 3 accumulator].
A detailed analysis of the calculated line of trajectory of a
failed screw cap/end cap for each of the accumulators has been
conducted, resulting in the identification of several areas where
systems and/or structural components could potentially be damaged.
Although all of the failures to date have occurred on the ground, an
in-flight failure affecting such components could potentially have
an adverse effect on the controllability of the aeroplane.
This directive gives instructions to amend the Airplane Flight
Manual (AFM), remove two accumulators (Hydraulic System No. 2 and
No. 3) from the aeroplane and conduct repetitive ultrasonic
inspections [for cracks] of the Hydraulic System No. 1, Inboard
Brake and Outboard Brake accumulators that are not identified by the
letter ``T'' after the serial number (S/N) on the identification
plate for cracks until they are replaced by new accumulators P/N
601R75139-1 (11093-4).

Required actions also include deactivating the hydraulic system No. 3
accumulator. You may obtain further information by examining the MCAI
in the AD docket.

Relevant Service Information

Bombardier has issued Canadair Regional Jet Temporary Revision (TR)
RJ/186-1, dated August 24, 2010, to the Limitations section, Normal
Procedures section, and Abnormal Procedures section of the Canadair
Regional Jet Airplane Flight Manual (AFM), CSP A-012. Canadair Regional
Jet TR RJ/186-1, dated August 24, 2010, advises the flightcrew that for
certain airplanes the hydraulic 3B pump is selected ``on'' instead of
``auto'' for all phases of flight.

----------------------------------------------------------------------------------------------------------------

The actions described in this service information as outlined in the
``Discussion'' section above, are intended to correct the unsafe
condition identified in the MCAI.

FAA's Determination and Requirements of This 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 issuing this AD because we
evaluated all pertinent information and determined the unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Differences Between the 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 required 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 AD.

Explanation of Affected Accumulators

The actions specified in the MCAI apply only to Tactair
accumulators. Certain actions in this AD apply to all accumulators.
This is a result of the unsafe condition, which is due to the location
of the accumulators and potential damage resulting from the release of
the accumulator screw cap/end cap. This is the reason for the
deactivation of the hydraulic system No. 3 accumulator and removal of
the hydraulic system No. 2 accumulator.

Interim Action

This AD does not require the removal of the hydraulic system No. 3
accumulator, or replacement of the hydraulic system No. 1, inboard
brake, and outboard brake accumulators, in Part IV and Part VII of the
Canadian Airworthiness Directive CF-2010-24, dated August 3, 2010. The
planned compliance time for the removal of the hydraulic system No. 3
accumulator, or replacement of the hydraulic system No. 1, inboard
brake, and outboard brake accumulators, in Part IV and Part VII of the
Canadian Airworthiness Directive CF-2010-24, dated August 3, 2010,
would allow enough time to provide notice and opportunity for prior
public comment on the merits of those actions. Therefore, we are
considering further rulemaking to address this issue.

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because seven
cases of on-ground hydraulic accumulator screw cap/end cap failure have
been experienced on Model CL-600-2B19 airplanes, resulting in the loss
of the associated hydraulic system and high-energy impact damage to
adjacent systems and structure. The lowest number of flight cycles
accumulated at the time of failure, to date, has been 6,991 flight
cycles.
A detailed analysis of the calculated line of trajectory of a
failed screw cap/end cap for each of the accumulators has been
conducted, resulting in the identification of several areas where
systems and/or structural components could potentially be damaged, fuel
lines and wires included. Although all of the failures to date have
occurred on the ground, an in-flight failure affecting such components
could consequently reduce the controllability of the airplane.
Therefore, we determined that notice and opportunity for public comment
before issuing this AD are impracticable and that good cause exists for
making this amendment effective in fewer than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. We invite you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include ``Docket No. FAA-2010-1037; Directorate
Identifier 2010-NM-202-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to https://www.regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

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.

[[Page 64638]]

Regulatory Findings

We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will 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 AD:
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 AD and placed it in the AD docket.

FAA AD Differences

Note 3: This AD differs from the MCAI and/or service information as
follows:
(1) This AD does not require the removal of the hydraulic system
No. 3 accumulator, or replacement of the hydraulic system No. 1,
inboard brake, and outboard brake accumulators, in Part IV and Part VII
of the Canadian Airworthiness Directive CF-2010-24, dated August 3,
2010.
(2) The actions specified in Canadian Airworthiness Directive CF-
2010-24, dated August 3, 2010, apply only to Tactair accumulators. The
actions required by paragraphs (h) and (i) of this AD apply to all
accumulators in the positions specified in paragraphs (h) and (i) of
this AD.

Other FAA AD Provisions

(s) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, New
York Aircraft Certification Office (ACO), ANE-170, 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, Continuing 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.
(3) Reporting Requirements: For any reporting requirement in this
AD, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501
et seq.), the Office of Management and Budget (OMB) has approved the
information collection requirements and has assigned OMB Control Number
2120-0056.
