ACTION: Final rule.
AGENCY:
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:
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 [inspections of various
fuel system components such as shields,
harnesses, sleeves, and sealant] 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
August 6, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of August 6, 2008.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of
proposed rulemaking (NPRM) to amend
14 CFR part 39 to include an AD that
would apply to the specified products.
That supplemental NPRM was
published in the Federal Register on
May 1, 2008 (73 FR 23990). That
supplemental 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 [inspections of various
fuel system components such as shields,
harnesses, sleeves, and sealant] are required
to prevent potential ignition sources inside
the fuel system, which could result in a fuel
tank explosion. Revision has been made to
Part 2 ‘‘Airworthiness Limitation Items’’ of
the DHC–8–400 Maintenance Requirements
Manual to introduce the required
maintenance tasks.
The corrective action is revising the
Airworthiness Limitations Section 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
received no comments on the
supplemental NPRM or on the
determination of the cost to the public.
mstockstill on PROD1PC66 with RULES
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed in the supplemental NPRM.
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.
VerDate Aug<31>2005
17:12 Jul 01, 2008
Jkt 214001
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
about 38 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 $3,040, 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.

DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
I
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
I
2008–13–08 Bombardier, Inc. (Formerly de
Havilland, Inc.): Amendment 39–15571.
Docket No. FAA–2008–0178; Directorate
Identifier 2007–NM–366–AD.
Effective Date
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
Sfmt 4700
(a) This airworthiness directive (AD)
becomes effective August 6, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier
Model DHC–8–400, DHC–8–401, and DHC–
8–402 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 (g) 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 [inspections of various
fuel system components such as shields,
harnesses, sleeves, and sealant] are required
to prevent potential ignition sources inside
the fuel system, which could result in a fuel
tank explosion. Revision has been made to
Part 2 ‘‘Airworthiness Limitation Items’’ of
the DHC–8–400 Maintenance Requirements
Manual 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.

[A]ssessment showed that supplemental maintenance tasks
[inspections of various fuel system components such as shields,
harnesses, sleeves, and sealant] 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 August 6, 2008.
The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (NPRM) to
amend 14 CFR part 39 to include an AD that would apply to the specified
products. That supplemental NPRM was published in the Federal Register
on May 1, 2008 (73 FR 23990). That supplemental 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
[inspections of various fuel system components such as shields,
harnesses, sleeves, and sealant] are required to prevent potential
ignition sources inside the fuel system, which could result in a
fuel tank explosion. Revision has been made to Part 2
``Airworthiness Limitation Items'' of the DHC-8-400 Maintenance
Requirements Manual to introduce the required maintenance tasks.
The corrective action is revising the Airworthiness Limitations Section
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 received no comments on the supplemental NPRM or on the
determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed in the
supplemental NPRM.
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 about 38 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 $3,040, 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 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

2008-13-08 Bombardier, Inc. (Formerly de Havilland, Inc.): Amendment
39-15571. Docket No. FAA-2008-0178; Directorate Identifier 2007-NM-
366-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective August
6, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier Model DHC-8-400, DHC-8-
401, and DHC-8-402 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 (g) 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
[inspections of various fuel system components such as shields,
harnesses, sleeves, and sealant] are required to prevent potential
ignition sources inside the fuel system, which could result in a
fuel tank explosion. Revision has been made to Part 2
``Airworthiness Limitation Items'' of the DHC-8-400 Maintenance
Requirements Manual 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.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 60 days after the effective date of this AD, or
before December 16, 2008, whichever occurs first, revise the ALS of
the Instructions for Continued Airworthiness to incorporate the
inspection requirements of Dash 8 Q400 (Bombardier) Temporary
Revision (TR) ALI-69, dated February 9, 2007, to Section 4, ``Fuel
System Limitations,'' of Part 2, ``Airworthiness Limitation Items,''
of the Bombardier Dash 8 Q400 Maintenance Requirements Manual,
Product Support Manual (PSM) 1-84-7 (``the TR to the MRM''). For all
fuel system limitations tasks contained in the TR to the MRM, the
initial compliance times start at the later of the ``Threshold'' and
``Grace Period'' times specified in Table 1 of this AD, and the
repetitive inspections must be accomplished thereafter at the
interval specified in the TR to the MRM, except as provided by
paragraphs (f)(2) and (g)(1) of this AD.

first.
------------------------------------------------------------------------
Note 2: The actions required by paragraph (f)(1) of this AD may
be done by inserting a copy of Dash 8 Q400 (Bombardier) TR ALI-69
into the Airworthiness Limitations Section of the Bombardier Dash 8
Q400 MRM PSM1-84-7. When this TR has been included in general
revisions of the MRM, the general revisions may be inserted in the
MRM, provided the relevant information in the general revision is
identical to that in Dash 8 Q400 (Bombardier) TR ALI-69.
(2) After accomplishing the actions specified in paragraph
(f)(1) of this AD, no alternative inspections or inspection
intervals may be used unless the inspections or inspection intervals
are part of a later revision of Bombardier Dash 8 Q400 MRM, PSM 1-
84-7, Revision 4, dated October 30, 2003, that is approved by the
Manager, New York Aircraft Certification Office (ACO), FAA, or
Transport Canada Civil Aviation (TCCA) (or its delegated agent); or
unless the inspections or inspection intervals are approved as an
alternative method of compliance (AMOC) in accordance with the
procedures specified in paragraph (g)(1) of this AD.
FAA AD Differences
Note 3: This AD differs from the MCAI and/or service information
as follows: No differences.
