SUMMARY: We are adopting a new
airworthiness directive (AD) for the
VerDate Aug<31>2005
16:57 Feb 08, 2008
Jkt 214001
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 December 3, 2007 (72 FR
67870). 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 CL–600–2B19
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 showed that sealant has
not been applied to bolts on the collector fuel
tanks or the transfer ejector fuel pumps. Lack

of sealant on the above-noted locations, if not
corrected, could result in arcing and
potential ignition source inside the fuel tank
during lightning strikes and consequent fuel
tank explosion. To correct the unsafe
condition, this directive mandates the
application of sealant to the bolts that attach
various fittings on the collector fuel tanks,
[an inspection for a fillet seal and if
necessary application of fillet seal] to the
edges of the transfer ejector pumps and [an
inspection for sealant and if necessary
application of sealant] to the bolts that attach
the transfer ejector pump to the transfer
ejector pump casing.
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.
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 626 products of U.S. registry. We
also estimate that it will take about 31
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 a negligible
amount 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
$1,552,480, or $2,480 per product.

Federal Register / Vol. 73, No. 28 / Monday, February 11, 2008 / Rules and Regulations
Authority for This Rulemaking
List of Subjects in 14 CFR Part 39
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.
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
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
2008–03–19 Bombardier, Inc. (Formerly
Canadair): Amendment 39–15370.
Docket No. FAA–2007–0262; Directorate
Identifier 2007–NM–247–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective March 17, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model
CL–600–2B19 (Regional Jet Series 100 & 440)
airplanes, serial numbers 7003 through 7067
and 7069 through 7924; 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–600–2B19
aircraft fuel system against new fuel tank
safety standards, introduced in Chapter 525

assessed using Transport Canada Policy
Letter No. 525–001 to determine if mandatory
corrective action is required.
The assessment showed that sealant has
not been applied to bolts on the collector fuel
tanks or the transfer ejector fuel pumps. Lack
of sealant on the above-noted locations, if not
corrected, could result in arcing and
potential ignition source inside the fuel tank
during lightning strikes and consequent fuel
tank explosion. To correct the unsafe
condition, this directive mandates the
application of sealant to the bolts that attach
various fittings on the collector fuel tanks,
[an inspection for a fillet seal and if
necessary application of fillet seal] to the
edges of the transfer ejector pumps and [an
inspection for sealant and if necessary
application of sealant] to the bolts that attach

referenced by Fokker 50 Maintenance Review
Board (MRB) Tasks Number 530000–00–04
and 530000–00–08 [currently required per
AD (BLA) 2002–061], did not show the
correct inspection areas. In addition to the
existing procedure, the area at the kink in the
bottom fuselage skin, the actual chine line,
must be inspected. Investigation revealed
that a number of aircraft have already passed
the relevant inspection thresholds of 20,000
and 45,000 flight cycles by a considerable
margin. As a result, it may be possible that
cracks have developed and remained

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:
7663
Recently, it was discovered that the
inspection procedure as described by Fokker
50 Non-Destructive Testing Manual (NDTM),
Part 6, Chapter 53–30–02, which is
referenced by Fokker 50 Maintenance Review
Board (MRB) Tasks Number 530000–00–04
and 530000–00–08 [currently required per
AD (BLA) 2002–061], did not show the
correct inspection areas. In addition to the
existing procedure, the area at the kink in the
bottom fuselage skin, the actual chine line,
must be inspected. Investigation revealed
that a number of aircraft have already passed
the relevant inspection thresholds of 20,000
and 45,000 flight cycles by a considerable
margin. As a result, it may be possible that
cracks have developed and remained
undetected. To prevent future use of the
incorrect procedure in NDTM, Part 6, chapter
53–30–02, Fokker Services has removed this
procedure from the NDTM and replaced by
chapter 53–30–03 (refer to NDTM Temporary
Revisions No. 53–004 and 53–005 dated
September 15, 2006). Furthermore the Fokker
50/60 Maintenance Planning Document (refer
to MPD Temporary Revision No. 53–009
dated August 15, 2006) has been revised to
delete references to the incorrect procedure
and to include references to the correct
procedure of NDTM, Part 6, chapter 53–30–
03. This condition, if not corrected, could
result in failure of the fuselage bottom skin.
Since an unsafe condition has been identified
that is likely to exist or develop on aircraft
of this type design, CAA–NL has originally
published AD NL–2006–009, which is now
replaced by NL–2006–009 R1.
This directive requires a one-time
inspection of the fuselage bottom skin at the
chine line, of the area not covered by the
procedure of NDTM, Part 6, chapter 53–30–
02. This one-time inspection consists of two
parts:
*
*
*
*
The unsafe condition is cracking and
subsequent failure of the fuselage
bottom skin, which could result in
reduced structural integrity of the
fuselage. This AD requires actions that
are intended to address the unsafe
condition described in the MCAI.
DATES: This AD becomes effective
February 26, 2008.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of February 26, 2008.
We must receive comments on this
AD by March 12, 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 December 3, 2007 (72
FR 67870). 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
CL-600-2B19 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 showed that sealant has not been applied to bolts

of sealant on the above-noted locations, if not corrected, could
result in arcing and potential ignition source inside the fuel tank
during lightning strikes and consequent fuel tank explosion. To
correct the unsafe condition, this directive mandates the
application of sealant to the bolts that attach various fittings on
the collector fuel tanks, [an inspection for a fillet seal and if
necessary application of fillet seal] to the edges of the transfer
ejector pumps and [an inspection for sealant and if necessary
application of sealant] to the bolts that attach the transfer
ejector pump to the transfer ejector pump casing.

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.
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 626 products of U.S.
registry. We also estimate that it will take about 31 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 a negligible
amount 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 $1,552,480, or $2,480 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.
List of Subjects in 14 CFR Part 39
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 adding the following new AD:
2008-03-19 Bombardier, Inc. (Formerly Canadair): Amendment 39-15370.
Docket No. FAA-2007-0262; Directorate Identifier 2007-NM-247-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective March
17, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Bombardier Model CL-600-2B19 (Regional
Jet Series 100 & 440) airplanes, serial numbers 7003 through 7067
and 7069 through 7924; 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-600-2B19 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 showed that sealant has not been applied to bolts
on the collector fuel tanks or the transfer ejector fuel pumps. Lack
of sealant on the above-noted locations, if not corrected, could
result in arcing and potential ignition source inside the fuel tank
during lightning strikes and consequent fuel tank explosion. To
correct the unsafe condition, this directive mandates the
application of sealant to the bolts that attach various fittings on
the collector fuel tanks, [an inspection for a fillet seal and if
necessary application of fillet seal] to the edges of the transfer
ejector pumps and [an inspection for sealant and if necessary
application of sealant] to the bolts that attach the transfer
ejector pump to the transfer ejector pump casing.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 5,000 flight hours after the effective date of this
AD: For airplanes with serial numbers 7003 through 7067 and 7069
through 7797, apply sealant to bolts on the collector fuel tanks
according to the Accomplishment Instructions of Bombardier Service
Bulletin 601R-28-051, Revision A, dated March 30, 2005.
(2) Within 5,000 flight hours after the effective date of this

Accomplishment Instructions of Bombardier Service Bulletin 601R-28-
060, Revision A, dated March 30, 2005.
(3) If during the inspection required by paragraph (f)(2) of
this AD any fillet seal is found missing from the edge of the
transfer ejector pump or sealant is found missing from any of the
bolts, prior to further flight, apply fillet seal and sealant as
applicable to the affected areas according to the Accomplishment
Instructions of Bombardier Service Bulletin 601R-28-060, Revision A,
dated March 30, 2005.
(4) Application of sealant prior to the effective date of this
AD according to Bombardier Service Bulletin 601R-28-051, dated May
12, 2003, satisfies the requirements of paragraph (f)(1) of this AD.
