AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing 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:
Three cases of in-flight loss of cabin pressurization have been
reported, resulting from failure of a bulkhead check valve in
combination with failure of an air supply duct.
In addition to mandating inspection, rework and/or replacement
of the air supply ducts, Airworthiness Directive (AD) CF-2003-05
(subsequently revised to CF-2003-05R1) [which corresponds to FAA AD
2004-22-08] mandated the incorporation of a 4000 flight-hour
repetitive inspection task for bulkhead check valves, Part Numbers
(P/N) 92E20-3 and 92E20-4, into the approved maintenance schedule.
However, this repetitive inspection task has since been superseded
by a 3000 flight-hour periodic discard task for these bulkhead check
valves.
This directive mandates revision of the approved maintenance
schedule to incorporate the discard task for bulkhead check valves,
P/N 92E20-3 and 92E20-4, and supersedes the instructions in
Corrective Actions, Part A, of AD CF-2003-05R1, dated 7 February
2006.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective November 9, 2010.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of November 9,
2010.
On December 2, 2004 (69 FR 62807, October 28, 2004), the Director
of the Federal Register approved the incorporation by reference of
certain other publications listed in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on April 5, 2010 (75 FR
17086). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Three cases of in-flight loss of cabin pressurization have been
reported, resulting from failure of a bulkhead check valve in
combination with failure of an air supply duct.
In addition to mandating inspection, rework and/or replacement
of the air supply ducts, Airworthiness Directive (AD) CF-2003-05
(subsequently revised to CF-2003-05R1) [which corresponds to FAA AD
2004-22-08] mandated the incorporation of a 4000 flight-hour
repetitive inspection task for bulkhead check valves, Part Numbers
(P/N) 92E20-3 and 92E20-4, into the approved maintenance schedule.
However, this repetitive inspection task has since been superseded
by a 3000 flight-hour periodic discard task for these bulkhead check
valves.
This directive mandates revision of the approved maintenance
schedule to incorporate the discard task for bulkhead check valves,
P/N 92E20-3 and 92E20-4, and supersedes the instructions in
Corrective Actions, Part A, of AD CF-2003-05R1, dated 7 February
2006.
You may obtain further information by examining the MCAI in the AD
docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received.
Request to Provide Credit for Actions Accomplished Per Previous Issue
of Service Bulletin
Air Wisconsin requests that credit be provided for actions
accomplished in accordance with a previous issue of a service bulletin.
Air Wisconsin states that paragraph (g)(3) of the NPRM specifies that
actions accomplished in accordance with Bombardier Alert Service
Bulletin A601R-21-053, dated November 8, 2001, are considered
acceptable for compliance; however, paragraph (i) of the NPRM states
that Bombardier Alert Service Bulletin A601R-21-053, Revision `A,'
dated January 28, 2003, needs to be accomplished. Air Wisconsin states
that the NPRM should provide credit for actions accomplished in
accordance with Bombardier Alert Service Bulletin A601R-21-053, dated
November 8, 2001; and Revision `A,' dated January 28, 2003. Air
Wisconsin states that Revision `A' did not affect airplanes on which
actions were accomplished in accordance with the original issue of that
service bulletin. Air Wisconsin states that its affected airplanes were
modified in accordance with Bombardier Alert Service Bulletin A601R-21-
053, dated November 8, 2001.
We agree that credit should be given for actions done in accordance
with Bombardier Alert Service Bulletin A601R-21-053, dated November 8,
2001, and note that this AD does provide credit. In the ``Restatement
of Requirements of AD 2004-22-08, Amendment 39-13836'' section of this
AD, we refer to the latest revision of the service bulletin, Bombardier
Alert Service Bulletin A601R-21-053, Revision `A,' dated January 28,
2003, for accomplishing the actions specified in paragraphs (h) and (i)
of this AD. In paragraph (g)(3) of this AD, we provide credit for
actions done before December 2, 2004 (the effective date of AD 2004-22-
08) in accordance with Bombardier Alert Service Bulletin A601R-21-053,
dated November 8, 2001, with the corresponding actions in paragraphs
specified in paragraphs (h) and (i) of this AD. We have not changed the
AD in regard to this issue. Norman -Payroll No: 68828 -Folios: 14-17 -

Request To Clarify the Requirements of Paragraph (j) of the NPRM
Comair, Inc. (Comair) notes that paragraph (j) of the NPRM proposes
to revise the Airworthiness Limitations
[[Page 61349]]
section of the Instructions for Continued Airworthiness to include the
information in Bombardier Temporary Revision (TR) 1-2-39, dated
December 12, 2008, to Section 2--Systems and Powerplant Program, of
Part 1 of the Bombardier CL-600-2B19 Maintenance Requirement Manual
(MRM). Comair states that the MRM is not structured to incorporate Part
1 items into Part 2 of the MRM. Comair notes that Note 3 of the NPRM
allows the TR to be removed once the information in TR 1-2-39 has been
incorporated into a general revision. Comair notes that Revision 14,
dated September 10, 2009, of the MRM has incorporated the information
in TR 1-2-39.
We infer that Comair is requesting that we clarify the requirements
of paragraph (j) of the NPRM. We agree that clarification is necessary.
The intent of revising Part 2 of the Airworthiness Limitations section
is to prohibit approval of any alternative replacement times or
structural inspection intervals for this bulkhead check valve. But, we
have clarified Note 3 of this AD to specify Part 2 of the Airworthiness
Limitations section of the MRM. Note 3 of this AD states that the
actions required by paragraph (j) of this AD may be done by inserting a
copy of Bombardier TR 1-2-39, dated December 12, 2008, into the MRM,
which introduces Bombardier Task 21-51-21-13. When Bombardier Task 21-
51-21-13 has been included in general revisions of the MRM, the general
revisions may be inserted into Part 2 of the Airworthiness Limitations
section of the MRM, provided the relevant information in the general
revision is identical to that in the TR.
Request To Clarify the Intent of Paragraph (j) of the NPRM
Comair states that if the intent of paragraph (j) of the NPRM is to
introduce the task into its proper part of the MRM, that is, Part 1,
then doing so would contradict the rationale the FAA previously
provided in AD 2004-22-08, Amendment 39-13836, (69 FR 62807, October
28, 2004). In AD 2004-22-08, the FAA responded to two requests to
consider the MRM Task Number 21-51-21-07 as an alternative to using
Bombardier Alert Service Bulletin A601R-21-054, dated November 8, 2001.
Comair points out that in AD 2004-22-08 the FAA stated, ``Although Part
1 of the MRM is accepted by the FAA, it is not approved, as is Part 2
of the Airworthiness Limitations section. We cannot control revisions
of the MRM; therefore, a task could be changed or deleted, and the AD
requirements would be modified without our approval.'' Comair points
out that by mandating the TR, the FAA is now requiring the
documentation that it previously rejected incorporating in AD 2004-22-
08.
We infer that Comair is requesting clarification of the
requirements of paragraph (j) of the NPRM. While the FAA reviews and
acknowledges the contents of Part 1 of the MRM, Part 1 does not require
FAA approval to be changed. Consequently, the FAA cannot control
revisions to this section of the MRM. However, the FAA does approve the
contents of Part 2 of the MRM, which becomes legally enforceable. A
task may be altered or deleted and may nullify the intent of the AD.
However, operators may request approval of an AMOC to allow the use of
a particular task card, provided a specified revision and date are
adhered to. Any subsequent revisions would require a new AMOC request
to ensure that the AD requirements are still met. We have not changed
the AD in regard to this issue.
Request To Allow Continuation of Previously Issued AMOCs
Comair requests that paragraph (l)(1) of the NPRM be revised to
accept previously issued AMOCs. Comair states that it has received
AMOCs from the New York Aircraft Certification Office that have allowed
it to perform inspections using Comair task cards for complying with
MRM Task 21-51-21-07 instead of Bombardier Alert Service Bulletin
A601R-21-054, dated November 8, 2001.
We agree that the previously issued AMOCs to Comair continue to
meet the requirements of this AD because they incorporated the bulkhead
check valve discard task that is required by paragraph (j) of this AD.
While we are not accepting all previously issued AMOCs that were
granted for AD 2004-22-08, we have revised paragraph (l)(1) of this AD
to accept those two specific AMOCs granted to Comair.
Conclusion
We reviewed the available data, including the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously. We determined that these
changes will not increase the economic burden on any operator or
increase the scope of the AD.
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 required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD affects
about 644 products of U.S. registry.
The actions that are required by AD 2004-22-08 and retained in this
AD take about 15 work-hours per product, at an average labor rate of
$85 per work hour. Required parts cost about $0 per product. Based on
these figures, the estimated cost of the currently required actions is
$1,869 per product.
We estimate that it takes about 1 work-hour per product to comply
with the new requirement to revise the ALI. The average labor rate is
$85 per work-hour. Based on these figures, we estimate the cost of this
requirement of the AD on U.S. operators to be $54,740, or $85 per
product.
We estimate that it takes about 5 work-hours per product to comply
with the new inspection requirement. The average labor rate is $85 per
work-hour. Required parts would cost about $594 per product, per
replacement cycle. 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
inspection requirements of the AD on U.S. operators to be $656,236, or
$1,019 per product, per replacement cycle.
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
[[Page 61350]]
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-13836 (69 FR
62807, October 28, 2004) and adding the following new AD:
2010-20-17 Bombardier, Inc.: Amendment 39-16452. Docket No. FAA-
2010-0276; Directorate Identifier 2009-NM-144-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
9, 2010.
Affected ADs
(b) This AD supersedes AD 2004-22-08, Amendment 39-13836.
Applicability
(c) This AD applies to all Bombardier, Inc. Model CL-600-2B19
(Regional Jet Series 100 & 440) airplanes, serial numbers 7003 and
subsequent, certificated in any category.
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 (l) 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 21: Air
conditioning.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Three cases of in-flight loss of cabin pressurization have been
reported, resulting from failure of a bulkhead check valve in
combination with failure of an air supply duct.
In addition to mandating inspection, rework and/or replacement
of the air supply ducts, Airworthiness Directive (AD) CF-2003-05
(subsequently revised to CF-2003-05R1) [which corresponds to FAA AD
2004-22-08] mandated the incorporation of a 4 000 flight-hour
repetitive inspection task for bulkhead check valves, Part Numbers
(P/N) 92E20-3 and 92E20-4, into the approved maintenance schedule.
However, this repetitive inspection task has since been superseded
by a 3000 flight-hour periodic discard task for these bulkhead check
valves.
This directive mandates revision of the approved maintenance
schedule to incorporate the discard task for bulkhead check valves,
P/N 92E20-3 and 92E20-4, and supersedes the instructions in
Corrective Actions, Part A, of AD CF-2003-05R1, dated 7 February
2006.
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.
Restatement of Requirements of AD 2004-22-08, Amendment 39-13836:
Service Information Clarifications
(g) Paragraphs (g)(1), (g)(2), and (g)(3) of this AD pertain to
the service information referenced in this AD.
(1) Although Bombardier Alert Service Bulletin A601R-21-053,
Revision `A,' dated January 28, 2003; and Bombardier Alert Service
Bulletin A601R-21-054, dated November 8, 2001; specify to submit
certain information to the manufacturer, this AD does not include
such a requirement.
(2) Bombardier Alert Service Bulletin A601R-21-054, dated
November 8, 2001, recommends sending all damaged check valves to the
manufacturer for analysis; however, this AD does not include that
requirement.
(3) Accomplishment of the actions specified in Bombardier Alert
Service Bulletin A601R-21-053, dated November 8, 2001, before
December 2, 2004 (the effective date of AD 2004-22-08), is
considered acceptable for compliance with the applicable actions
specified in this AD.
Repetitive Inspections/Related Corrective Actions
(h) Within 500 flight hours after December 2, 2004: Do the
detailed inspections and related corrective actions required by
paragraphs (h)(1) and (h)(2) of this AD, per the Accomplishment
Instructions of Bombardier Alert Service Bulletin A601R-21-053,
Revision `A,' dated January 28, 2003; and Bombardier Alert Service
Bulletin A601R-21-054, dated November 8, 2001; as applicable.
(1) For airplanes having bulkhead check valves with part number
(P/N) 92E20-3/-4, as identified in Bombardier Alert Service Bulletin
A601R-21-054, dated November 8, 2001: Inspect the left- and right-
hand bulkhead check valves for damage (cracking, breakage). If any
damage is found, before further flight, replace the damaged valve.
Repeat the inspection at intervals not to exceed 4,000 flight hours
until the replacement required by paragraph (j) of this AD is done.
(2) For airplanes having serial numbers 7003 through 7067
inclusive, and 7069 through 7477 inclusive: Inspect the left- and
right-hand air supply ducts of the rear bulkhead for damage
(tearing, delamination, or cracking). If any damage is found, before
further flight, either rework or replace the damaged air supply
duct, which ends the inspections for that air supply duct only. If
no damage is found, repeat the inspection thereafter at intervals
not to exceed 500 flight hours until accomplishment of paragraph (i)
of this AD.
Note 2: For the purposes of this AD, a detailed inspection is
defined as: ``An intensive visual examination of a specific
structural area, system, installation, or assembly to detect damage,
failure, or irregularity. Available lighting is normally
supplemented with a direct source of good lighting at intensity
deemed appropriate by the inspector. Inspection aids such as mirror,
[[Page 61351]]
magnifying lenses, etc., may be used. Surface cleaning and elaborate
access procedures may be required.''
Terminating Action for Repetitive Inspections of Air Supply Ducts
(i) Except as required by paragraph (h)(2) of this AD, for
airplanes having serial numbers 7003 through 7067 inclusive, and
7069 through 7477 inclusive: Within 5,000 flight hours after
December 2, 2004, either rework or replace the left- and right-hand
air ducts, as applicable, per the Accomplishment Instructions of
Bombardier Alert Service Bulletin A601R-21-053, Revision `A,' dated
January 28, 2003; and Bombardier Alert Service Bulletin A601R-21-
054, dated November 8, 2001; as applicable. Accomplishment of this
paragraph ends the repetitive inspections required by paragraph
(h)(2) of this AD.
New Requirements of This AD:
Actions and Compliance
(j) For airplanes having serial numbers 7003 and subsequent:
Within 60 days after the effective date of this AD, revise the
Airworthiness Limitations section of the Instructions for Continued
Airworthiness to include the information in Bombardier Temporary
Revision (TR) 1-2-39, dated December 12, 2008, to Section 2--Systems
and Powerplant Program, of Part 1 of the Bombardier CL-600-2B19
Maintenance Requirement Manual (MRM). This task requires replacement
of the bulkhead check valves having P/N 92E20-3 or 92E20-4 at
intervals not to exceed 3,000 flight hours. Operate the airplane
thereafter according to the limitations and procedures in the TR.
(k) Thereafter, except as provided in paragraph (j) of this AD,
no alternative replacement times or structural inspection intervals
may be approved for this bulkhead check valve.
Note 3: The actions required by paragraph (j) of this AD may be
done by inserting a copy of Bombardier TR 1-2-39, dated December 12,
2008, into the MRM, which introduces Task 21-51-21-13. When
Bombardier Task 21-51-21-13 has been included in general revisions
of the MRM, the general revisions may be inserted into Part 2 of the
Airworthiness Limitations section of the MRM, provided the relevant
information in the general revision is identical to that in the TR.
FAA AD Differences
Note 4: This AD differs from the MCAI and/or service information
as follows: No differences.
Other FAA AD Provisions
(l) 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. Two AMOCs approved previously in
accordance with AD 2004-22-08, Amendment 39-13836, are approved as
AMOCs for the corresponding provisions of this AD. These two
approved AMOCs are identified in paragraphs (l)(1)(i) and (l)(1)(ii)
of this AD. All other AMOCs approved previously in accordance with
AD 2004-22-08, Amendment 39-13836, are not approved as AMOCs with
this AD.
(i) An AMOC approved by the New York ACO on November 17, 2004,
in response to Comair AMOC request memo, dated November 10, 2004.
(ii) An AMOC approved by the New York ACO on October 13, 2006,
in response to Comair AMOC request memo, dated September 19, 2006.
(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.
