[Docket No. FAA–2008–0300; Directorate
Identifier 2008–NM–019–AD; Amendment
39–15552; AD 2008–12–09]
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 March 17, 2008 (73 FR
14189). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
RIN 2120–AA64
Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
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:
*
*
*
*
*
The assessment and lightning tests showed
that certain fuel tube self-bonded couplings
do not provide sufficient lightning current
capability. The assessment also showed that
single failure of the integral bonding wire of
the self-bonded couplings could affect
electrical bonding between the tubes.
Insufficient electrical bonding between fuel
tubes or insufficient current capability of fuel
tube couplings, if not corrected, could result
in arcing and potential ignition source[s]
inside the fuel tank during lightning strikes
and consequent fuel tank explosion. * * *
We are issuing this AD to require
actions to correct the unsafe condition
on these products.
DATES: This AD becomes effective July
16, 2008.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of July 16, 2008.

Bombardier Aerospace has completed a
system safety review of the CL–600–2C10/
CL–600–2D24 aircraft fuel system against
new fuel tank safety standards, introduced in
Chapter 525 of the Airworthiness Manual
through Notice of Proposed Amendment
(NPA) 2002–043. The identified noncompliances were assessed using Transport
Canada Policy Letter No. 525–001 to
determine if mandatory corrective action is
required.
The assessment and lightning tests showed
that certain fuel tube self-bonded couplings
do not provide sufficient lightning current
capability. The assessment also showed that
single failure of the integral bonding wire of
the self-bonded couplings could affect
electrical bonding between fuel tubes.
Insufficient electrical bonding between fuel
tubes or insufficient current capability of fuel
tube couplings, if not corrected, could result
in arcing and potential ignition source[s]
inside the fuel tank during lightning strikes
and consequent fuel tank explosion. To
correct the unsafe condition, this directive
mandates the replacement of certain fuel tube
couplings with redesigned couplings.
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.
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
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.
E:\FR\FM\11JNR1.SGM
11JNR1
Federal Register / Vol. 73, No. 113 / Wednesday, June 11, 2008 / Rules and Regulations
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 160 products of U.S. registry. We
also estimate that it will take about 32
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $80 per work-hour.
Required parts will cost about $0 per
product. Where the service information
lists required parts costs that are
covered under warranty, we have
assumed that there will be no charge for
these parts. 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 this AD
to the U.S. operators to be $409,600, or
$2,560 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
VerDate Aug<31>2005
15:03 Jun 10, 2008
Jkt 214001
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

Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
Bombardier Aerospace has completed a
system safety review of the CL–600–2C10/
CL–600–2D24 aircraft fuel system against
new fuel tank safety standards, introduced in
Chapter 525 of the Airworthiness Manual
through Notice of Proposed Amendment
(NPA) 2002–043. The identified noncompliances were assessed using Transport
Canada Policy Letter No. 525–001 to
determine if mandatory corrective action is
required.
The assessment and lightning tests showed
that certain fuel tube self-bonded couplings
do not provide sufficient lightning current
capability. The assessment also showed that
single failure of the integral bonding wire of
the self-bonded couplings could affect
electrical bonding between fuel tubes.
Insufficient electrical bonding between fuel
tubes or insufficient current capability of fuel
tube couplings, if not corrected, could result
in arcing and potential ignition source[s]
inside the fuel tank during lightning strikes
and consequent fuel tank explosion. To
correct the unsafe condition, this directive
mandates the replacement of certain fuel tube
couplings with redesigned couplings.
Actions and Compliance
(f) Within 4,500 flight hours after the
effective date of this AD, unless already
done, do the following actions.
(1) For airplanes on which Bombardier
Service Bulletin 670BA–28–014, dated
January 4, 2005, has not been incorporated as
of the effective date of this AD: Replace fuel
tube couplings inside the wing and center
fuel tanks with redesigned couplings, in
accordance with Part A of the
Accomplishment Instructions of Bombardier
Service Bulletin 670BA–28–014, Revision A,
dated May 7, 2007.
(2) For airplanes on which Bombardier
Service Bulletin 670BA–28–014, dated
January 4, 2005, has been incorporated as of
the effective date of this AD: Do a visual

affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of this AD to the
U.S. operators to be $409,600, or $2,560 per product.

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
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:
2008-12-09 Bombardier, Inc. (Formerly Canadair): Amendment 39-15552.
Docket No. FAA-2008-0300; Directorate Identifier 2008-NM-019-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 16,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model CL-600-2C10 (Regional
Jet Series 700, 701, & 702) airplanes, serial numbers 10003 through
10169 inclusive; and Model CL-600-2D24 (Regional Jet Series 900)
airplanes, serial numbers 15001 through 15025 inclusive;
certificated in any category.
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
CL-600-2C10/CL-600-2D24 aircraft fuel system against new 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 assessed using Transport Canada
Policy Letter No. 525-001 to determine if mandatory corrective
action is required.
The assessment and lightning tests showed that certain fuel tube
self-bonded couplings do not provide sufficient lightning current
capability. The assessment also showed that single failure of the
integral bonding wire of the self-bonded couplings could affect
electrical bonding between fuel tubes.
Insufficient electrical bonding between fuel tubes or
insufficient current capability of fuel tube couplings, if not
corrected, could result in arcing and potential ignition source[s]
inside the fuel tank during lightning strikes and consequent fuel
tank explosion. To correct the unsafe condition, this directive
mandates the replacement of certain fuel tube couplings with
redesigned couplings.
Actions and Compliance
(f) Within 4,500 flight hours after the effective date of this
AD, unless already done, do the following actions.
(1) For airplanes on which Bombardier Service Bulletin 670BA-28-
014, dated January 4, 2005, has not been incorporated as of the
effective date of this AD: Replace fuel tube couplings inside the
wing and center fuel tanks with redesigned couplings, in accordance
with Part A of the Accomplishment Instructions of Bombardier Service
Bulletin 670BA-28-014, Revision A, dated May 7, 2007.
(2) For airplanes on which Bombardier Service Bulletin 670BA-28-
014, dated January 4, 2005, has been incorporated as of the
effective date of this AD: Do a visual inspection of the aft
scavenge ejector fuel couplings inside the left- and right-hand wing
fuel tanks to determine if redesigned couplings are installed, and
replace with redesigned couplings as applicable, in accordance with
Part B of the Accomplishment Instructions of Bombardier Service
Bulletin 670BA-28-014, Revision A, dated May 7, 2007.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
