ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
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:
During testing, it was discovered that when the outflow valve
(OFV) manual mode connector is not connected, the manual mode motor
and altitude limitation are not properly tested. Consequently, a
disconnect
[[Page 22647]]
of the OFV manual mode and/or a related wiring failure could
potentially result in a dormant loss of several CPC [cabin pressure
control] backup/safety functions, including OFV manual control,
altitude limitation, emergency depressurization and smoke clearance.
* * *
* * * * *
This AD requires actions that are intended to address the unsafe
condition described in the MCAI.

SUPPLEMENTARY INFORMATION:
Discussion
The Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2009-08, dated March 9, 2009 (referred to after this as ``the MCAI''),
to correct an unsafe condition for the specified products. The MCAI
states:
During testing, it was discovered that when the outflow valve
(OFV) manual mode connector is not connected, the manual mode motor
and altitude limitation are not properly tested. Consequently, a
disconnect of the OFV manual mode and/or a related wiring failure
could potentially result in a dormant loss of several CPC [cabin
pressure control] backup/safety functions, including OFV manual
control, altitude limitation, emergency depressurization and smoke
clearance. This deficiency is applicable to CPC units, Part Number
(P/N) GG670-98002-3 and -5, and CPCP [cabin pressure control panel],
Part Number GG670-98001-5, -7 and -9.
This [Canadian] directive mandates an interim repetitive check
of the OFV manual mode motor and altitude limitation functions,
followed by modification (software update) of the CPC units and the
CPCP.
The corrective action for findings of improper OFV manual mode motor or
altitude limitation functions is replacing the valve with a new or
serviceable valve. You may obtain further information by examining the
MCAI in the AD docket.
Relevant Service Information
Bombardier has issued Alert Service Bulletin A670BA-21-022, dated
August 3, 2006. Bombardier has also issued Tasks 21-32-01-000-801 and
21-32-01-400-801 of the Bombardier CRJ Regional Jet Series Aircraft
Maintenance Manual, CSP B-001, Part 2, Volume 1, Revision 28, dated
January 20, 2009. 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 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.
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 of
possible latent failure of several CPC backup/safety functions,
including OFV manual control, altitude limitation, emergency
depressurization, and smoke clearance, which could result in altitude
limitation, emergency depressurization, and smoke clearance issues.
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-2009-0448; Directorate
Identifier 2009-NM-052-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.
[[Page 22648]]
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 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.

Subject
(d) Air Transport Association (ATA) of America Code 21: Air
Conditioning.
Reason
(e) The mandatory continued airworthiness information (MCAI)
states:
During testing, it was discovered that when the outflow valve
(OFV) manual mode connector is not connected, the manual mode motor
and altitude limitation are not properly tested. Consequently, a
disconnect of the OFV manual mode and/or a related wiring failure
could potentially result in a dormant loss of several CPC [cabin
pressure control] backup/safety functions, including OFV manual
control, altitude limitation, emergency depressurization and smoke
clearance. This deficiency is applicable to CPC units, Part Number
(P/N) GG670-98002-3 and -5, and CPCP [cabin pressure control panel],
Part Number GG670-98001-5, -7 and -9.
This [Canadian] directive mandates an interim repetitive check
of the OFV manual mode motor and altitude limitation functions,
followed by modification (software update) of the CPC units and the
CPCP.
The corrective action for findings of improper OFV manual mode
motor and altitude limitation functions is replacing the valve with
a new or serviceable valve.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 450 flight hours after the effective date of this AD,
inspect the OFV for proper operation of the manual mode motor and
altitude limitation functions, in accordance with Part A of the
Accomplishment Instructions of Bombardier Alert Service Bulletin
A670BA-21-022, dated August 3, 2006 (``the service bulletin''). If
the OFV manual mode motor or altitude limitation functions do not
operate properly, before further flight, do the actions specified in
paragraphs (f)(1)(i) and (f)(1)(ii) of this AD. Repeat the
inspection thereafter at intervals not to exceed 450 flight hours.
Accomplishing the actions specified in paragraph (f)(3) of this AD
terminates the requirements of this paragraph.
(i) Make sure that the electrical connectors, MPE23P1 and
MPE23P2, are connected to the OFV.
(ii) Repeat the inspection of the OFV for proper operation of
the manual mode motor and altitude limitation functions, in
accordance with Part A of the service bulletin. If the OFV manual
mode motor or altitude limitation functions do not operate properly,
before further flight, replace the OFV with a new or serviceable
valve in accordance with Tasks 21-32-01-000-801 and 21-32-01-400-801
of the Bombardier CRJ Regional Jet Series Aircraft Maintenance
Manual, CSP B-001, Part 2, Volume 1, Revision 28, dated January 20,
2009, and do the inspection of the OFV specified in paragraph (f)(1)
of this AD.
(2) Prior to accomplishing paragraph (f)(3) of this AD: Install
modified CPC units, Part Number GG670-98002-7, in accordance with
Part B of the Accomplishment Instructions of Bombardier Alert
Service Bulletin A670BA-21-022, dated August 3, 2006.
(3) Installing modified CPCPs, Part Number GG670-98001-11, in
accordance with Part C of the Accomplishment Instructions of
Bombardier Alert Service Bulletin A670BA-21-022, dated August 3,
2006, terminates the requirements of paragraph (f)(1) of this AD.
FAA AD Differences
Note 1: This AD differs from the MCAI and/or service information
as follows:
(1) The MCAI and Bombardier Alert Service Bulletin A670BA-21-
022, dated August 3, 2006, do not describe corrective actions for
findings of improper OFV manual mode motor and altitude limitation
functions. This AD requires the actions in paragraphs (f)(1)(i) and
(f)(1)(ii) of this AD, which includes replacing the valve if the OFV
manual mode motor or altitude limitation functions do not operate
properly.
(2) This AD does not require the software update of the CPC
units specified in Part 2 of the MCAI, and the software update of
the CPCP specified in Part 3 of the MCAI. The planned compliance
times for those actions 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.
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: Fabio Buttitta, Aerospace
Engineer, Airframe and Mechanical Systems Branch, ANE-171, FAA, New
York ACO, 1600 Stewart Avenue, Suite 410, Westbury, New York 11590;
telephone (516) 228-7303; 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
[[Page 22649]]
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, the
Office of Management and Budget (OMB) has approved the information
collection requirements and has assigned OMB Control Number 2120-
0056.
