ACTION: Final rule.
AGENCY:
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:
Bombardier Aerospace has completed a
system safety review of the aircraft fuel
system against fuel tank safety standards
* * *.
[A]ssessment showed that supplemental
maintenance tasks [for certain bonding
jumpers, wiring harnesses, and hydraulic
systems, among other items] are required to
prevent potential ignition sources inside the
fuel system, which could result in a fuel tank
explosion. * * *
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective
November 28, 2008.

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 June 20, 2008 (73 FR 35095)
and proposed to supersede AD 2008–
06–02, Amendment 39–15414 (73 FR
13100, March 12, 2008). That NPRM
proposed to correct an unsafe condition
for the specified products. The MCAI
states:
mstockstill on PROD1PC66 with RULES
Bombardier Aerospace has completed a
system safety review of the aircraft fuel
system against fuel tank standards
introduced in Chapter 525 of the
Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002–043. The
identified non-compliances were then
assessed using Transport Canada Policy
Letter No. 525–001, to determine if
mandatory corrective action is required.
The assessment showed that supplemental
maintenance tasks [for certain bonding
jumpers, wiring harnesses, and hydraulic
systems, among other items] are required to
prevent potential ignition sources inside the
fuel system, which could result in a fuel tank
explosion. Revision has been made to
Canadair Regional Jet Model CL–600–2B19
Maintenance Requirements Manual, CSP
A–053, Part 2, Appendix D, ‘‘Fuel System
Limitations’’ to introduce the required
maintenance tasks.
The corrective action is revising the
Airworthiness Limitations Section
(ALS) of the Instructions for Continued
Airworthiness to incorporate new
limitations for fuel tank systems. 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.

Jkt 217001
Request To Clarify Airplanes Subject to
Certain Tasks
Comair and Air Wisconsin request
that we clarify which airplanes are
subject to certain tasks identified in the
NPRM. Comair states that Tasks 28–11–
00–601, 28–11–00–602, and 28–11–00–
604 require inspections on airplanes
that are post-modsum or post-service
bulletin. Comair states that since the
NPRM restates the phase-in
requirements of Appendix D, ‘‘Fuel
System Limitations,’’ of Part 2,
‘‘Airworthiness Requirements,’’ of
Bombardier CL–600–2B19 Maintenance
Requirements Manual CSP–053,
Revision 7, dated May 10, 2007, (the
‘‘MRM’’), the ‘‘effectivity’’ statements
specified in the MRM for the tasks
should also be included. Air Wisconsin
notes that in the MRM, Task 28–11–00–
604 applies only to post-Service
Bulletin 601R–28–059 airplanes. Air
Wisconsin questions if the intent of the
NPRM is for Task 28–11–00–604 to also
be performed on pre-service bulletin
airplanes.
We agree with the commenters that
we must clarify which airplanes are
affected by Tasks 28–11–00–601, 28–
11–00–602, and 28–11–00–604.
Although the MCAI does not refer to the
‘‘effectivity’’ statement specified in the
MRM, we have determined only those
airplanes identified in the ‘‘effectivity’’
statement specified in the MRM are
subject to the corresponding tasks.
We have revised paragraph (f)(2) of
this AD by adding paragraphs (f)(2)(i)
and (f)(2)(ii) to clarify that only
airplanes identified in the ‘‘effectivity’’
statement specified in the MRM for
Tasks 28–11–00–601, 28–11–00–602,
and 28–11–00–604 are subject to the
action specified in paragraph (f)(2) of
this AD.
We have also removed Tasks 28–11–
00–601, 28–11–00–602, and 28–11–00–
604 from paragraph (g)(1)(i) of this AD
and added new paragraph (g)(1)(iii) to
clarify the compliance times for
airplanes not identified in paragraph
(f)(2)(ii) of this AD.
Removed Reference to ‘‘Later
Revisions’’ of Service Information
We removed the reference to ‘‘later
revisions’’ of the applicable service
information in paragraphs (f)(1), (f)(5),
and (g)(2) of this AD to be consistent
with FAA policy and Office of the
Federal Register regulations. We may
consider approving the use of later
revisions of the service information as
an alternative method of compliance
with this AD, as provided by paragraph
(h)(1) of this AD.

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
We estimate that this AD will affect
689 products of U.S. registry. We also
estimate that it will take about 1 workhour per product to comply with the
basic requirements of this AD. The
average labor rate is $80 per work-hour.
Based on these figures, we estimate the
cost of this AD to the U.S. operators to
be $55,120, or $80 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 AD will not
have federalism implications under
E:\FR\FM\24OCR1.SGM
24OCR1
Federal Register / Vol. 73, No. 207 / Friday, October 24, 2008 / Rules and Regulations
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 https://
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

Affected ADs
(b) This AD supersedes AD 2008–06–02,
Amendment 39–15414.
Applicability
(c) This AD applies to all Bombardier
Model CL–600–2B19 (Regional Jet Series 100
and 440) airplanes, certificated in any
category, all serial numbers.
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 (h)(1) 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 28: Fuel.
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Bombardier Aerospace has completed a
system safety review of the aircraft fuel
system against fuel tank standards
introduced in Chapter 525 of the
Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002–043. The
identified non-compliances were then
assessed using Transport Canada Policy
Letter No. 525–001, to determine if
mandatory corrective action is required.
The assessment showed that supplemental
maintenance tasks [for certain bonding
jumpers, wiring harnesses, and hydraulic
systems, among other items] are required to
prevent potential ignition sources inside the
fuel system, which could result in a fuel tank
explosion. Revision has been made to
Canadair Regional Jet Model CL–600–2B19
Maintenance Requirements Manual, CSP A–
053, Part 2, Appendix D, ‘‘Fuel System
Limitations’’ to introduce the required
maintenance tasks.
The corrective action is revising the
Airworthiness Limitations Section (ALS) of
the Instructions for Continued Airworthiness
to incorporate new limitations for fuel tank
systems.

SUMMARY: We are adopting a new
airworthiness directive (AD) for
Maryland Air Industries, Inc., Model
Fairchild F–27 and FH–227 Series
Airplanes. This AD requires operators to
modify their airplanes and revise their
inspection or maintenance programs to
incorporate instructions for
maintenance and inspection of the fuel
tank systems, as appropriate, by
December 16, 2008, using information
developed in accordance with Special
Federal Aviation Regulation 88 (SFAR
88). This AD results from fuel system
safety reviews done on similar airplane
models in accordance with SFAR 88.
These safety reviews identified potential
unsafe conditions on Model Fairchild
F–27 and FH–227 series airplanes for
which the type certificate holder,
Maryland Air Industries, Inc., has not
conducted SFAR 88 safety reviews, has
not provided corrective actions, and
does not plan to do so. We are issuing
this AD to reduce the potential of
ignition sources inside fuel tanks,
which, in combination with flammable
fuel vapors, could result in fuel tank
explosions and consequent loss of the
airplane.
DATES: This AD is effective November
28, 2008.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://

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:
Bombardier Aerospace has completed a system safety review of the
aircraft fuel system against fuel tank safety standards * * *.
[A]ssessment showed that supplemental maintenance tasks [for
certain bonding jumpers, wiring harnesses, and hydraulic systems,
among other items] are required to prevent potential ignition
sources inside the fuel system, which could result in a fuel tank
explosion. * * *
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective November 28, 2008.
The Director of the Federal Register approved the incorporation by
reference

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 June 20, 2008 (73 FR
35095) and proposed to supersede AD 2008-06-02, Amendment 39-15414 (73
FR 13100, March 12, 2008). That NPRM proposed to correct an unsafe
condition for the specified products. The MCAI states:
Bombardier Aerospace has completed a system safety review of the
aircraft fuel system against fuel tank standards introduced in
Chapter 525 of the Airworthiness Manual through Notice of Proposed
Amendment (NPA) 2002-043. The identified non-compliances were then
assessed using Transport Canada Policy Letter No. 525-001, to
determine if mandatory corrective action is required.
The assessment showed that supplemental maintenance tasks [for
certain bonding jumpers, wiring harnesses, and hydraulic systems,
among other items] are required to prevent potential ignition
sources inside the fuel system, which could result in a fuel tank
explosion. Revision has been made to Canadair Regional Jet Model CL-
600-2B19 Maintenance Requirements Manual, CSP A-053, Part 2,
Appendix D, ``Fuel System Limitations'' to introduce the required
maintenance tasks.
The corrective action is revising the Airworthiness Limitations Section
(ALS) of the Instructions for Continued Airworthiness to incorporate
new limitations for fuel tank systems. 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 Clarify Airplanes Subject to Certain Tasks
Comair and Air Wisconsin request that we clarify which airplanes
are subject to certain tasks identified in the NPRM. Comair states that
Tasks 28-11-00-601, 28-11-00-602, and 28-11-00-604 require inspections
on airplanes that are post-modsum or post-service bulletin. Comair
states that since the NPRM restates the phase-in requirements of
Appendix D, ``Fuel System Limitations,'' of Part 2, ``Airworthiness
Requirements,'' of Bombardier CL-600-2B19 Maintenance Requirements
Manual CSP-053, Revision 7, dated May 10, 2007, (the ``MRM''), the
``effectivity'' statements specified in the MRM for the tasks should
also be included. Air Wisconsin notes that in the MRM, Task 28-11-00-
604 applies only to post-Service Bulletin 601R-28-059 airplanes. Air
Wisconsin questions if the intent of the NPRM is for Task 28-11-00-604
to also be performed on pre-service bulletin airplanes.
We agree with the commenters that we must clarify which airplanes
are affected by Tasks 28-11-00-601, 28-11-00-602, and 28-11-00-604.
Although the MCAI does not refer to the ``effectivity'' statement
specified in the MRM, we have determined only those airplanes
identified in the ``effectivity'' statement specified in the MRM are
subject to the corresponding tasks.
We have revised paragraph (f)(2) of this AD by adding paragraphs
(f)(2)(i) and (f)(2)(ii) to clarify that only airplanes identified in
the ``effectivity'' statement specified in the MRM for Tasks 28-11-00-
601, 28-11-00-602, and 28-11-00-604 are subject to the action specified
in paragraph (f)(2) of this AD.
We have also removed Tasks 28-11-00-601, 28-11-00-602, and 28-11-
00-604 from paragraph (g)(1)(i) of this AD and added new paragraph
(g)(1)(iii) to clarify the compliance times for airplanes not
identified in paragraph (f)(2)(ii) of this AD.
Removed Reference to ``Later Revisions'' of Service Information
We removed the reference to ``later revisions'' of the applicable
service information in paragraphs (f)(1), (f)(5), and (g)(2) of this AD
to be consistent with FAA policy and Office of the Federal Register
regulations. We may consider approving the use of later revisions of
the service information as an alternative method of compliance with
this AD, as provided by paragraph (h)(1) of this AD.
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
We estimate that this AD will affect 689 products of U.S. registry.
We also estimate that it will take about 1 work-hour per product to
comply with the basic requirements of this AD. The average labor rate
is $80 per work-hour. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $55,120, or $80 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 AD will not have federalism implications
under
[[Page 63351]]
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 https://
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.

Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
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 39-15414 (73 FR
13100, March 12, 2008) and adding the following new AD:
2008-22-03 Bombardier, Inc. (Formerly Canadair): Amendment 39-15698.
Docket No. FAA-2008-0643; Directorate Identifier 2008-NM-094-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
28, 2008.
Affected ADs
(b) This AD supersedes AD 2008-06-02, Amendment 39-15414.
Applicability
(c) This AD applies to all Bombardier Model CL-600-2B19
(Regional Jet Series 100 and 440) airplanes, certificated in any
category, all serial numbers.
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 (h)(1) 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 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Bombardier Aerospace has completed a system safety review of the
aircraft fuel system against fuel tank standards introduced in
Chapter 525 of the Airworthiness Manual through Notice of Proposed
Amendment (NPA) 2002-043. The identified non-compliances were then
assessed using Transport Canada Policy Letter No. 525-001, to
determine if mandatory corrective action is required.
The assessment showed that supplemental maintenance tasks [for
certain bonding jumpers, wiring harnesses, and hydraulic systems,
among other items] are required to prevent potential ignition
sources inside the fuel system, which could result in a fuel tank
explosion. Revision has been made to Canadair Regional Jet Model CL-
600-2B19 Maintenance Requirements Manual, CSP A-053, Part 2,
Appendix D, ``Fuel System Limitations'' to introduce the required
maintenance tasks.
The corrective action is revising the Airworthiness Limitations
Section (ALS) of the Instructions for Continued Airworthiness to
incorporate new limitations for fuel tank systems.
Restatement of Certain Requirements of AD 2008-06-02
(f) Unless already done, do the following actions.
(1) Within 60 days after April 16, 2008 (the effective date of
AD 2008-06-02), revise the Airworthiness Limitations Section (ALS)
of the Instructions for Continued Airworthiness to incorporate the
inspection and maintenance requirements, as applicable, in Appendix
D, ``Fuel System Limitations,'' of Part 2, ``Airworthiness
Requirements,'' of Bombardier CL-600-2B19 Maintenance Requirements

33-01-601, and 29-33-01-602. Except as required by paragraph (g)(1)
of this AD, for those task numbers, the initial compliance times
start at the applicable time specified in paragraphs (f)(2), (f)(3),
and (f)(4) of this AD, and the repetitive inspections must be
accomplished thereafter at the interval specified in the MRM, except
as provided by paragraphs (f)(5) and (h)(1) of this AD.
(2) For airplanes identified in paragraphs (f)(2)(i) and
(f)(2)(ii) of this AD, the initial compliance time for Tasks 28-11-
00-601, 28-11-00-602, 28-11-00-603, and 28-11-00-604 is within 5,000
flight hours after April 16, 2008. Thereafter, these tasks must be
accomplished within the repetitive interval specified in Appendix D,
``Fuel System Limitations,'' of Part 2, ``Airworthiness

Airplanes having more than 15,000 flight hours as of April 16, 2008,
and which are identified in the applicable ``effectivity'' statement
specified in the MRM for Tasks 28-11-00-601, 28-11-00-602, and 28-
11-00-604.
(3) For Task 29-33-01-601, the initial compliance time is within
5,000 flight hours after April 16, 2008. Thereafter, Task 29-33-01-
601 must be accomplished within the repetitive interval specified in
Appendix D, ``Fuel System Limitations,'' of Part 2, ``Airworthiness
Requirements,'' of Bombardier CL-600-2B19 Maintenance Requirements
Manual CSP-053, Revision 7, dated May 10, 2007.
(4) For airplanes having more than 27,500 flight hours as of
April 16, 2008, the initial compliance time for Task 29-33-01-602 is
within 2,500 flight hours after April 16, 2008. Thereafter, this
task must be accomplished within the repetitive interval specified
in Appendix D, ``Fuel System Limitations,'' of Part 2,
``Airworthiness Requirements,'' of Bombardier CL-600-2B19
Maintenance Requirements Manual CSP-053, Revision 7, dated May 10,
2007.
(5) After accomplishing the actions specified in paragraphs
(f)(1), (f)(2), (f)(3), and (f)(4) of this AD, no alternative
inspections/limitation tasks or inspection/limitation task intervals
may be used unless the inspection/limitation task or inspection/
limitation task interval is approved as an alternative method of
compliance (AMOC) in accordance with the procedures specified in
paragraph (h)(1) of this AD.
New Requirements of This AD: Actions and Compliance
(g) Unless already done, do the following actions.
