-----------------------------------------------------------------------
SUMMARY: 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:
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.
* * * * *
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.
DATES: This AD becomes effective November 4, 2010.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 4,
2010.

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 http://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.
