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:
SUMMARY:

system against fuel tank safety standards
* * *.
[A]ssessment showed that supplemental
maintenance tasks [inspections of fuel tank
bonding jumpers, wiring harnesses, and

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 23995). 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 safety 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 fuel tank
bonding jumpers, wiring harnesses, and
drain valve components, among other items
and actions; and applicable corrective
actions] are required to prevent potential
ignition sources within the fuel system,
which could result in a fuel tank explosion.
Revisions have been made to Part 2
‘‘Airworthiness Limitations List’’ of the
E:\FR\FM\13AUR1.SGM
13AUR1
47030
Federal Register / Vol. 73, No. 157 / Wednesday, August 13, 2008 / Rules and Regulations
DHC–8 Maintenance Program Manuals 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 NPRM or
on the determination of the cost to the
public.
Clarification of Identity of Model DHC–
8–201 Airplanes
We have clarified the identity of
certain airplanes as listed in the
supplemental NPRM by correctly
identifying them throughout this AD as
Model DHC–8–201 airplanes.
Removal of Reference to ‘‘a Later
Revision’’ of Certain Maintenance
Program Manuals (MPMs)
We removed the reference to ‘‘a later
revision of Part 2 ‘Airworthiness
Limitations List’ of the applicable de
Havilland Dash 8 Series MPM’’ from
paragraph (f)(4) of this AD and removed
Table 3 of the NPRM, which listed the
MPMs (and renumbered the subsequent
table accordingly). We removed the
reference to the use of ‘‘later revisions’’
of the applicable service information
from this AD to be consistent with FAA
policy. This change will not increase the
economic burden on any operator, nor
will it increase the scope of the AD,
since operators may request approval to
use a later revision of the referenced
service information as an alternative
method of compliance, under the
provisions of paragraph (g) of this AD.
hsrobinson on PROD1PC76 with RULES
Conclusion
We reviewed the available data 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
VerDate Aug<31>2005
15:55 Aug 12, 2008
Jkt 214001
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 122 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 $9,760, 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.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
I
PART 39—AIRWORTHINESS
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
2008–13–09 Bombardier, Inc. (Formerly de
Havilland, Inc.): Amendment 39–15572.
Docket No. FAA–2008–0179; Directorate
Identifier 2007–NM–367–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective September 17, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier
Model DHC–8–102, DHC–8–103, DHC–8–
106, DHC–8–201, DHC–8–202, DHC–8–301,
DHC–8–311, and DHC–8–315 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 safety 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 fuel tank
bonding jumpers, wiring harnesses, and
drain valve components, among other items
and actions; and applicable corrective
actions] are required to prevent potential
ignition sources within the fuel system,
which could result in a fuel tank explosion.
Revisions have been made to Part 2
‘‘Airworthiness Limitations List’’ of the
DHC–8 Maintenance Program Manuals 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.
47031
(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 fuel system limitations tasks
identified in the de Havilland temporary
revisions (TRs) to Part 2, ‘‘Airworthiness
Limitations List,’’ of the Dash 8 Series
Maintenance Program Manuals (‘‘the
MPMs’’). The TRs are listed in Table 1 of this
AD. For the tasks identified in the TRs, the
initial compliance times start at the later of
the applicable ‘‘Threshold’’ and ‘‘Grace
Period’’ times specified in Table 2 of this AD,
and the repetitive limitation tasks must be
accomplished thereafter at the interval
specified in the TRs, except as provided by
paragraphs (f)(2), (f)(3), (f)(4), and (g)(1) of
this AD.

landing gear) rib 5 forward attachment lug on
two A310 in-service aircraft. Laboratory
examination of one of the cracked ribs
confirmed that the crack is due to the
presence of pitting corrosion in the forward
lug holes. Also on both aircraft medium to
heavy corrosion was found in the forward
lugs on the opposite wing after removal of
the bushes. This situation if not detected,
could affect the structural integrity of the
MLG attachment. As an interim measure,
Airbus published Alert Service Bulletin
(ASB) A310–57A2088 to introduce a
repetitive detailed visual inspection (DVI) of
the forward attachment lug of MLG Rib 5.
EASA issued Emergency Airworthiness
Directive (EAD) 2006–0335–E [which
corresponds to FAA AD 2007–02–09] to
require the accomplishment of this repetitive
DVI.
In order to ensure the detection of any
crack at an early stage in the forward lug of
the RH (right-hand) and LH (left-hand) MLG
Rib 5 aft bearing attachment, the Type
Certificate holder has developed a new
inspection by means of ultrasonic method.
For the reasons described above, this new
inspection program is rendered mandatory by
this AD, which cancels and replaces the
requirement of EAD 2006–0335–E.
The corrective action includes
repairing or replacing MLG Rib 5, as

ACTION: Final rule.
-----------------------------------------------------------------------
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 fuel tank bonding jumpers, wiring harnesses, and
drain valve components, among other items and actions; and
applicable corrective actions] are required to prevent potential
ignition sources within 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 September 17, 2008.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of September 17,
2008.
ADDRESSES: You may examine the AD docket on the Internet at https://

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 23995). 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 safety 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 fuel tank bonding jumpers, wiring harnesses, and
drain valve components, among other items and actions; and
applicable corrective actions] are required to prevent potential
ignition sources within the fuel system, which could result in a
fuel tank explosion. Revisions have been made to Part 2
``Airworthiness Limitations List'' of the
[[Page 47030]]
DHC-8 Maintenance Program Manuals 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 NPRM or on the determination of
the cost to the public.
Clarification of Identity of Model DHC-8-201 Airplanes
We have clarified the identity of certain airplanes as listed in
the supplemental NPRM by correctly identifying them throughout this AD
as Model DHC-8-201 airplanes.
Removal of Reference to ``a Later Revision'' of Certain Maintenance
Program Manuals (MPMs)
We removed the reference to ``a later revision of Part 2
`Airworthiness Limitations List' of the applicable de Havilland Dash 8
Series MPM'' from paragraph (f)(4) of this AD and removed Table 3 of
the NPRM, which listed the MPMs (and renumbered the subsequent table
accordingly). We removed the reference to the use of ``later
revisions'' of the applicable service information from this AD to be
consistent with FAA policy. This change will not increase the economic
burden on any operator, nor will it increase the scope of the AD, since
operators may request approval to use a later revision of the
referenced service information as an alternative method of compliance,
under the provisions of paragraph (g) of this AD.
Conclusion
We reviewed the available data 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 about 122 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 $9,760, 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
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 adding the following new AD:
2008-13-09 Bombardier, Inc. (Formerly de Havilland, Inc.): Amendment
39-15572. Docket No. FAA-2008-0179; Directorate Identifier 2007-NM-
367-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective
September 17, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Bombardier Model DHC-8-102, DHC-8-
103, DHC-8-106, DHC-8-201, DHC-8-202, DHC-8-301, DHC-8-311, and DHC-
8-315 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 safety 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 fuel tank bonding jumpers, wiring harnesses, and
drain valve components, among other items and actions; and
applicable corrective actions] are required to prevent potential
ignition sources within the fuel system, which could result in a
fuel tank explosion. Revisions have been made to Part 2
``Airworthiness Limitations List'' of the DHC-8 Maintenance Program
Manuals 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 fuel
system limitations tasks identified in the de Havilland temporary
revisions (TRs) to Part 2, ``Airworthiness Limitations List,'' of
the Dash 8 Series Maintenance Program Manuals (``the MPMs''). The
TRs are listed in Table 1 of this AD. For the tasks identified in
the TRs, the initial compliance times start at the later of the
applicable ``Threshold'' and ``Grace Period'' times specified in
Table 2 of this AD, and the repetitive limitation tasks must be
accomplished thereafter at the interval specified in the TRs, except
as provided by paragraphs (f)(2), (f)(3), (f)(4), 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 the applicable TR listed in Table 1
of this AD into the ALS of the applicable MPM listed in Table 1 of
this AD. When the applicable TR has been included in general
revisions of the applicable MPM, the general revisions may be
inserted in the MPM, provided the relevant information in the
general revision is identical to that in the applicable TR.
(2) For those tasks with 6,000 flight hours/36 month limitation
task intervals: For airplanes that have accumulated 4,000 total
flight hours or more, or 24 months or more since new, as of the
effective date of this AD, do the initial limitation tasks within
2,000 flight hours or 12 months after the effective date of this AD,
whichever occurs first. Thereafter, repeat the limitation tasks at
intervals not to exceed 6,000 flight hours or 36 months, whichever
occurs first.
(3) For those tasks with 18,000 flight hours/108 month
limitation task intervals: For airplanes that have accumulated
12,000 total flight hours or more, or 72 months or more since new,
as of the effective date of this AD, do the initial limitation tasks
within 6,000 flight hours or 36 months after the effective date of
this AD, whichever occurs first. Thereafter, repeat the limitation
tasks at intervals not to exceed 18,000 flight hours or 108 months,
whichever occurs first.
(4) After accomplishing the actions specified in paragraphs
(f)(1), (f)(2), and (f)(3) of this AD, no alternative inspections/
limitation tasks or inspection/limitation task intervals may be used
unless the inspections/limitation tasks or inspection/limitation
task intervals are approved as an alternative method of compliance
(AMOC) in accordance with the procedures specified in paragraph
(g)(1) of this AD.
